			<content:encoded><![CDATA[<p>My name is Winston. Winston Perchhill. I am a happy member of a flock of three cockatiels, but it hasn’t always been like this. I would like to take you back to my earliest memories. </p>
<p>I was six months old and had been left in a bird shop by a man who was teaching me to whistle. He had told the owner of the shop to warn everyone to be careful when they came near me, because I was dangerous. It wasn’t clear to me what that meant, except that I probably wouldn&#8217;t get to visit with many people or other birds ever again. There I was, alone in my nice, large cage and separated from all of the other birds, some of whom looked to be close relatives of mine. They paid no attention to me at all, and I mostly contented myself by eating the food I was given and watching the controlled commotion around me, keeping an ear poised for any words I might have heard before. I spent the rest of my time whistling my little ditty, putting all of my heart and soul into every syllable and imagining that I was in a great mansion surrounded by birds of all kinds who were spellbound by my song. I determined not to forget even one note, because I felt in my bones that my song would be the key to me finding a new home, my forever home.</p>
<p>One day as I was busy whistling as usual, this strange-looking lady came in, walked past me, and went directly into the back of the shop where I had noticed most customers usually went. In a few minutes, while she was returning to the front with a package filled to the brim with seed, she stopped to listen to me. This was it; I knew it! I whistled with all my might, my nervous little body bending with the song and my swaying head reaching for the sky. I had won her! It was obvious!</p>
<p>&#8220;Does every cockatiel whistle that song, or is that unique to that bird?&#8221; she asked the owner, who was too busy with another customer to reply. <br/><br />
&#8220;Why is that bird here?&#8221; <br/><br />
&#8220;On consignment,&#8221; she was told. <br/><br />
&#8220;Male or female?&#8221; <br/><br />
&#8220;Male.&#8221; <br/><br />
&#8220;How old is he?&#8221; <br/><br />
&#8220;Six months.&#8221; <br/><br />
&#8220;Why is he here?&#8221; <br/><br />
&#8220;The family couldn’t keep him any longer.&#8221; <br/><br />
&#8220;How much would he cost?&#8221; <br/><br />
&#8220;Fifty dollars, and that includes the cage and the toys.&#8221; <br/><br />
&#8220;I&#8217;ll take him! Can I leave him here for a few hours while I do some other errands?&#8221; <br/><br />
“Sure.” </p>
<p>I was to have my own home again! A strange lady, granted, but she did know her music! When my lady came back, she was very happy to see me again. She put my cage into the back of our car and nestled me close to her in a small clear box. She talked and whistled to me all the way home, which turned out to be less than a great mansion, much less. My disappointment was tempered, however, the moment we went through the front door and I saw a tidy cage, inside of which were two beautiful yellow birds. They were smaller than I and we differed a lot in appearance; but they turned out to be pretty nice. The brighter one was quite talkative, although I could understand only a few of the things he said.</p>
<p>Those days we didn’t have much company, probably because in our house there also was a very old gentleman whom my lady was taking care of. So, although it was quiet, I had my birds, and my lady whistled to me all the while she worked and periodically reviewed my whole vocabulary. Then suddenly the old man was gone, and for two years my lady left our house before breakfast and returned after dark, until one day she came home for good, bringing with her two very tiny birds. We were together and had many visitors, and there was absolutely nothing to complain about. </p>
<p>The tiny birds seemed to enjoy being with the rest of us and my lady kept busy teaching me more things to say. We had settled on what I came to know as &#8220;The Marine Corps Hymn&#8221; to be &#8220;my&#8221; song. It fit me like a glove and I could whistle it perfectly within a couple of weeks. Every time strangers came into the house, I treated them to multiple renditions of it, to great acclaim.</p>
<p>The months drifted along uneventfully, and then a crisis came upon us. There were tears, and many people coming and going, measuring and removing furniture, and packing clothes and all the pictures and the pretty little china things that had decorated our house. My birds and I were put into the car and driven down the road for a few minutes, taken out, and carried into… a mansion. I was finally going to live in a great mansion! I stretched my neck to see what we were passing along the way inside and it was beyond my wildest dreams. There were birds in the bushes, birds in the trees, birds on the roof. They greeted us as we were carried inside, me whistling, of course, my Marine Hymn. It was bird heaven and I could have died right then and there and been satisfied!</p>
<p>We were placed in what was described as “our bedroom.” From our cages, we could look outside through a huge picture window, and my lady would put food on the porch for the outdoor birds to eat. They would fly in as one and land on the stone railing, impatiently waiting until the food was ready and my lady was gone, and then they would descend on the food, eating ravenously. This happened twice a day like clockwork and all of us birds, inside and out, would begin to get excited about the routine at least half an hour before feeding time. We were one big flock: the five of us inside watching our members on the other side of the window &#8211; little brown birds that chirped and huge mostly gray birds that had a very pleasant way of cooing. In the warm weather, we were joined by birds with red faces and little ones who were brown on the back and white on the front, while black-and-red birds ate down on the grass and noisy blue birds ate up in the trees. Once in a while some enormous black birds would soar overhead and in the evening ugly little birds dove around the porch eating right in the air.</p>
<p> On those warm days, my lady would put my cage in a small alcove on the porch, and I would whistle and talk to my friends from morning until evening, when I would be gently carried into my bedroom to rejoin my indoor birds for sleep. It was a wonderful time. My lady visited me throughout the day and often prompted me to say a few words, but mischievously I would say them only when I wanted to. On cold days, she would sit in a nearby room and talk to the five of us indoor birds, and I in turn would treat her to several choruses of my song. My indoor brothers and sisters would glance at each other in amazement and sit very quietly, listening to us. Life went on like that, and then death came.</p>
<p>First my original birds died, then one of the smaller ones. That left just one tiny gray bird and me in our bedroom. We did our best to keep each other company when the house was quiet and the outdoor birds had gone to their nests. My lady kept constant vigil, and the three of us had our hour together every evening just before sleep. Then one day I was all by myself inside with no tiny bedtime companion at all. I comforted myself with my whistling and of course I had my outdoor flock. I became content to sit in my cage and watch them bustle about and descend as one when hungry and fly away as one when scared or when their stomachs were full. Every year there were new members of the flock and every year I would find that some of those whom I had known in the past were missing. A strange big brown bird began to come regularly and perch on the stone railing, and my lady would hustle out and carry me inside when she saw him!  I thus learned that not all birds were my friends, and I began to call a warning when he would arrive.</p>

			<content:encoded><![CDATA[<p><a href="http://www.birds.com/blog/the-tale-of-winston-perchhill-%E2%80%93-part-one/">The Tale of Winston Perchhill &#8211; Part One</a></p>
<p>After the passage of many years, this mostly tranquil, comfortable life was snatched away from me when my lady and I left our great mansion. I had done my best to get her to stay, greeting every stranger and telling them, in my own words, that we were very happy there and did not want to go, to no avail. Again I was in the car, but this time it was not just a short ride. We went through whole neighborhoods, over rough roads and roads that went through great red rocks, and into places completely covered with trees. We parked in front of a little blue house surrounded by snow, and there was not another bird in sight! I had barely had time to say goodbye to my outdoor friends at the mansion and now I had no one, except my lady. I was miserable and she knew it.</p>
<p>She kept me by her side all day and took me with her whenever she went anywhere in the car. Although I had a big window to look out, there was nothing to see except those awful green trees and that snow on the ground. Oh, the occasional group of four-legged animals would go by; but I did miss my birds. I was so unhappy, I couldn’t eat. I couldn’t even whistle. I just sat on the bottom of my cage and dreamed of my lost flock. Nothing could make me forget and I got weaker and weaker. I could hear my lady talking about me to someone I could not see and one day she left me alone in the house for several hours. When she came home, she was carrying a huge new cage that held the two most beautiful birds I ever saw! They looked somewhat like me; but I’m just a couple of shades of gray, and they were pure white! I knew I was in love with one of them the moment I saw her, and immediately I stretched and got myself off the bottom of my cage.</p>
<p>When my lady let me out, I strolled right over to the white birds and began to whistle as I had never whistled before. I belted out &#8220;The Marine Corps Hymn&#8221; over and over, slightly spreading my wings and bowing to my new love. I did not feel the sting I should have felt from the incredulous looks I received from the white birds and I began to tell them in my own words how I felt about her: &#8220;I love you, pretty bird!&#8221; When my love turned her back on me and hurried away, I asked her &#8220;What&#8217;s the matter?&#8221; Even though my appetite was returning, I forgot to eat very much. It had been a long day, but I was still serenading. When we were put to bed, they were in their cage and I in mine. It didn’t seem fair that that other bird got to be near my love all night and I had to sleep by myself! I thought about her until I fell asleep; and when I awoke the next morning, a few hours earlier than usual, I began my serenade all over again.</p>
<p>When we were finally allowed out and she majestically ascended my hanging perch, I stood beneath her looking up, and whistled. I quickly learned that she had a hard heart, but I was determined to win her over. During the daytime, the white birds and I were always free to go out of our cages. I noticed they had a bit of a waddle that I didn’t have, but it was quite endearing. When we ate, they pecked away incessantly until they got their fill and I would choose each seed carefully and munch on it slowly, giving my lady a glance after my every bite, just to make sure that she could see I was really part of my new flock. My muscles were very weak, so I had to watch from a distance as my white birds climbed between cages and flew up to the highest bookshelves and ventured throughout the house. I was, however, able to explore their cage, which was a wonder, filled with toys of every sort. At first, the white birds would pair up against me, not willing to share; and my love would call to him in her coy little way, while I would wander around alone, sometimes letting my competition know that I was serious about turning the head of my newfound love.</p>
<p>I don’t recall exactly when I succeeded in that, but succeed I did, in a big way! I had suddenly become irresistible to her and she was coyly calling to me! My lady began referring to the other white bird as &#8220;my dear little orphan boy&#8221; and I could totally empathize with him, but this was love and I wasn’t going to miss out on a second of it! I was an old bird—sixteen and counting – and didn’t have much time left, but I was beginning to feel great.</p>
<p>I don&#8217;t miss the mansion anymore and I have begun to think about my old flock less and less. The warm weather has returned and there are dozens of birds outside, along with many more of those four-legged animals, some with their babies, and many other types of animals who weren&#8217;t here in the cold. I have my pure white love and our mutual white friend, and a comfortable, cozy cottage, and my lady. That&#8217;s a lot of things to whistle about and I whistle periodically from morning until sleep. I have taken up the chirp of the white birds that is much more musical than a simpler one I borrowed years ago. I have truly become one of them: we share our cages and we eat and sleep together, and we are happy. Would you believe it, I can fly now – mostly, however, in a downward trajectory; but my wings are getting stronger and I glide farther every day! My lady smiles a lot as she watches over us. She and I still review my words and my song every day; and I have gotten used to sitting on her shoulder while we have good, long talks. You know, I never once let my lady touch my back until I saw how much my white birds enjoy it; but now I can sit for hours letting my lady stroke my feathers and rub my face, and kiss me – right on the beak! It is, in fact, a very good life!</p>

			<content:encoded><![CDATA[<p>While <strong>zebra finch</strong> females utter single note, low-pitched <strong>calls</strong>, males have the ability to sing in a variety of frequencies, even producing a whistle that goes beyond a piano keyboard’s high end. Male birds make use of <strong>song</strong> to attract mates and to protect their territory. It is believed that the varied frequency of songs may be more attractive to females, as well as providing greater and more precise information. </p>
<p>The two variables affecting the pitch of a <a href="http://www.birds.com/activities/callings-sounds/" title="About Bird Calls and Sounds">bird&#8217;s song</a> are air pressure and muscle activity. Recent research has revealed that muscle activity plays the larger role in this respect. This study was conducted by Tobias Riede of the National Center for Voice and Speech (under the administration of the <a href="http://www.utah.edu/portal/site/uuhome/" title="University of Utah Website" target="_blank" rel="external">University of Utah</a>), as well as Franz Goller, and John H. Fisher. Funding for the research was provided by the National Institutes of Health. </p>
<p>The zebra finch&#8217;s vocal organ is called the syrinx, and measures a mere one-eighth of an inch on either side. It was already known, through past studies, that male zebra finches had larger vocal muscles controlling the syrinx than did the females. In this study the cartilage scaffold, which supports the bird’s syrinx, as well as the “labia” (the part that oscillates when air moves through it) in the syrinx, were investigated. This revealed that the male finch’s cartilage scaffold is larger, while the labia are a different shape to that of the female. Riede concluded that this must be so that the labia can be tensioned tightly by the muscles that pull the scaffold, so as to reach the high-frequency notes. </p>
<p>The <a href="http://www.birds.com/education/research-studies/" title="Bird Research and Studies">researchers</a> sought to study whether lung pressure or vocal muscle strength was the more important factor in the control of the male zebra finch’s pitch. They began by recording the sounds of six male finches and six female finches for a period of two weeks. Tubes containing air pressure sensors were implanted into an air sac. Specially designed equipment ensured that the birds could continue to fly and sing freely whilst measurements were taken and their sounds recorded again. The results showed that higher air pressure lead to higher pitch, indicating that lung pressure does affect song frequency. </p>
<p>Following this experiment, the researchers cut the nerves that control the birds&#8217; vocal muscles. They then recorded the birds&#8217; sounds as they sang and flew about. It was noted that the pitch of all birds dropped to approximately the same level and males were unable to produce high frequencies. The fact that they could no longer put sufficient tension on the labia showed that the vocal muscles play a key role in bird song pitch. </p>

<p>Scientists have noted that under certain conditions there is significant shrinkage in the size of the regions of the brain that control the <strong>singing</strong> <a href="http://www.birds.com/bird-care/behavior/" title="Bird Behavior">behavior</a> of the <strong>Gambel&#8217;s white-crowned sparrow</strong>. This drastic change is triggered by the withdrawal of the naturally occurring steroid hormone testosterone and the change is apparent within 12 hours. This scientific study is the first to report such a rapid regression of brain nuclei as a response to the withdrawal of a hormone and change in daylight conditions.</p>
<p>Once testosterone is removed from circulation, it takes just 12 hours for the volume of the song-control region, known as the HVC, to collapse. By the fourth day, thousands of HVC neurons have been destroyed. It is believed that this destruction is carried out by a cell suicide program known as apoptosis.</p>
<p>Natural seasonal changes were simulated and the effect on the brain of the sparrows monitored. It was noted that the song-control regions of the brain expands in the spring and summer. The purpose of this is to establish territories and attract mates for the Alaskan <a href="http://www.birds.com/activities/breeding/" title="Bird Breeding">breeding</a> season. Later in the summer, the same brain regions shrink as they prepare to migrate back to California. Similar research connected to seasonal changes has been carried out on the brains of reptiles, fish, amphibians and mammals such as mice, gerbils and even humans. But the degree of change in birds is far more significant than observed in other animals.</p>
<p>With the objective of gaining a better understanding of what happens the in song bird&#8217;s brain, the researchers were granted federal and state permits to capture 25 male birds. These were kept in captivity for 12 weeks and then exposed to 20 days of simulated long-day conditions which are comparable to what the sparrows would naturally experience during the breeding season in Alaska. In addition, the birds received testosterone implants.</p>
<p>With the approval of the UW&#8217;s Institutional Animal Care and Use Committee and the National Institute of Mental Health, at the end of the 20 days 6 of the birds were euthanized. The remaining 19 birds were castrated as well as having the implants removed to ensure that no testosterone would be circulating in their systems. The remainder of the birds were euthanized at pre-determined intervals.</p>
<p>The results of the research strongly indicate that regions of the brain that are sensitive to hormonal changes regress without testosterone. Conversely, an increase in hormones such as testosterone, could serve to protect neurons. These findings have led researchers to the conclusion that some form of hormone replacement therapy may provide protection against neurodegeneration, providing hope for people who suffer from age related degenerative brain diseases.</p>
<p>So next time you hear one of these little song <a href="http://www.birds.com/activities/calling-sounds/" title="Bird Calling Sounds">birds calling</a>, remember that the Gambel&#8217;s white-crowned sparrow could provide answers for scientists who are searching for ways to bring relief to thousands of people.</p>

			<content:encoded><![CDATA[<p><!--gardening.jpg|Bird Friendly Gardening-->
<p>Do you enjoy <strong>observing the antics of wild birds</strong> as they chatter away to each other? Is a bird song in the morning like music to your ears?  If the answer is yes, maybe you should consider creating or improving your garden to will attract ore varieties of <a href="http://www.birds.com/species/" title="Bird Species">bird species</a> to your home.</p>
<p><span id="more-661"></span></p>
<p>Naturally, <strong>wild birds</strong> are attracted to areas that provide food, water and cover (protection from weather and invading predators) and an area nesting. So to create that perfect garden and to attract birds, bird experts recommend careful planning and landscaping to maximize to attract and most diverse numbers of birds to your property. Experts recommend that a perfect habitat will offer birds a variety of native trees, shrubs, ground cover, vines, and wildflowers- each of which will provide both food and shelter.</p>
<p>By nature, <strong>birds are drawn to the functional benefits served by plants</strong>, which are more important than appearance. Bird enthusiasts are encouraged to choose plants not only based upon attractiveness but also on the purpose that each plant will serve. For example, trees and shrubs are ideal for meeting the needs of local birds.  A less spacious garden can still be graced with a variety of useful plants so the size of the garden is not important to attract wild birds. The trick is to know which plants to use and how to properly position them. Another good idea is to grow plants in groups particularly in a smaller garden space.</p>
<p><strong>Garden plants</strong> also have different qualities for <strong>attracting birds</strong>, and plants can be grouped into categories according to these characteristics. One category is the thorny, twiggy, or evergreen flora which provides shelter and protection from predators. Another second is the nut-, fruit-, seed- and nectar-bearing plants are known to provide nourishment.</p>
<p>These are just a few of ideas that <a href="http://www.birds.com/activities/bird-watching/" title="Bird Watching">bird watchers</a> and bird enthusiasts can consider when trying attracting birds into garden spots and hideaways. With the popularity of birding and with high season upon us, try creating your own bird sanctuary and experience what Mother Nature has to offer by attracting wild birds to your garden. Your planning and effort will be handsomely rewarded.</p>

			<content:encoded><![CDATA[<p>The male <strong>canary</strong>&#8216;s beautiful song has made it a wildly popular pet, around the world.  Today&#8217;s domesticated canaries all descended from a wild <a href="http://www.birds.com/species/" title="Bird Species">species</a> found in the <strong>Canary Islands</strong>. This species was first brought to Europe during the 1500&#8242;s. </p>
<p><span id="more-634"></span></p>
<p> During the next 500 years, many European breeders made their living breeding and <a href="http://www.birds.com/classifieds/" title="Sell your Birds online">selling canaries</a>. For example, canaries became the chief industry of the Harz region of Germany. Breeders soon developed different kinds of canary. By the 18th century, there were twenty-nine varieties. </p>
<p> Many of these varieties are available today, for pets. Some are bred for their colors. Others were developed for their shape, such as crested canaries. A third group of canaries were bred specifically to enhance their voices. For instance, the Roller Canary is known for its rolling songs. </p>
<p> <strong>Canary breeders</strong> often take their birds to shows, where judges rate the birds by their song or appearance. These shows take place in October and November, when the breeders&#8217; new male canaries are most likely to sing. </p>
<p> Today, canaries make ideal, easy pets for busy households. They don&#8217;t require constant attention, like some parrots and cockatiels. They live happily in cages, provided the cage is large enough. Toys in their cage can prevent boredom. A happy male canary can live and sing for up to 20 years. </p>

			<content:encoded><![CDATA[<p>Birds are very <strong>talented vocalists</strong>. They recognize each other over long distances and through thick shrubbery, using their voices. With a little practice, humans can also learn to <strong>recognize birds by their songs or calls</strong>.</p>
<p><span id="more-631"></span></p>
<p> <a href="http://www.birds.com/acitivities/bird-watching/" title="Bird Watching">Bird-watchers</a> often identify birds just by their voice. This is usually because birds are more often heard than seen. But in some bird species, even a good look won&#8217;t help you identify them. For instance, North America&#8217;s Alder and Willow flycatchers look identical, but have very different voices. Most observers can&#8217;t identify them until the bird begins to sing. </p>
<p> Hunters and scientists also learn bird calls- to lure in ducks or to tally what <a href="http://www.birds.com/species/" title="Bird Species">bird species</a> live in the area. </p>
<p> Interested in learning bird voices yourself?  While your written field guide may describe the sounds, it&#8217;s best to learn by ear.  Obtain a tape, CD, or online resource that has recordings of the birds in your area. Start by listening carefully to recordings of the most common birds. Then head outside to see if this helps you recognize these birds. </p>
<p> Once you have the common birds down, you can begin to work on more unusual songs. It takes practice. But you may soon be able to recognize your local birds as easily as you recognize a friend&#8217;s voice on the phone. </p>

			<content:encoded><![CDATA[<p>Does whistling like a bird really <a href="http://www.birds.com/activities/attracting-birds/" title="Attracting Birds">attract birds</a>? Or does it just make you look foolish? Does the bird understand when a facsimile is taking place? Does it think to itself how silly you look standing behind a bush quaking like a duck?</p>
<p><span id="more-615"></span></p>
<p>There are actually very few <a href="http://www.birds.com/education/" title="Educaction of Birds">resources</a> available for learning to whistle like a bird. Far easier to just learn how to whistle &#8212; period!  Easier still, to find material &#8212; CD&#8217;s of pre-recorded birdsongs more often than not &#8212; that teach your bird how to whistle. But apparently for the birder &#8211; the passionate individual trekking through the woods with a pair of binoculars and a guidebook, learning to whistle and imitating your favorite bird is a skill you either have or you don&#8217;t.</p>
<p>In some higher circles of <a href="http://www.birds.com/activities/bird-watching/" title="Bird Watching">bird watching</a>, the art of whistling is referred to mimicry. As if that changes anything. Mimicry is known to only a few. Rich Little is a darn good mimic, but his impersonation of Kirk Douglas will not attract a cardinal. (And his whistling ability sucks by the way). </p>
<p>For those who care, whistling can be traced to the 12th century just by Webster&#8217;s definition, but early man probably tried to mimic bird sounds as well. Their interest was in attracting dinner, not in attracting a bird to look and appreciate. </p>
<p>Back in the 1920&#8242;s, whistling achieved a certain amount of respectability. The late Agnes Woodward started a school for whistlers, which gained so much popularity that at one time her method was taught nationwide, mostly by voice teachers.</p>
<p>Getting back to birds however, in order to imitate a bird you need to be able to listen to the bird and fortunately there are many resources available that offer recorded bird <a href="http://www.musicians.com" title="Your Guide to Music and Musicians">songs</a>. Listen and repeat. The same strategy used so successfully in learning to ride a bike just may work when learning how to whistle like a spotted wren.</p>
<p>Only you don&#8217;t fall down as much.</p>

			<content:encoded><![CDATA[<p>Birds <strong>sing</strong> for a variety of reasons, and not all of these motivations are linked to <strong>displays of pleasure</strong>. As their primary form of communication, birds sing to <strong>greet</strong> one <strong>another</strong>, attract a potential mate, issue a warning and even mark and defend their territory.</p>
<p><span id="more-605"></span></p>
<p>Certainly birds do a lot more <strong>singing and chirping</strong> in the spring and summer than any other time of the year because it&#8217;s breeding time. But as the weather cools in the fall, many birds continue chirping away. Still looking for a mate? Hardly. Researchers have discovered  a physiological foundation specifically linked to testosterone, that keeps our feathered friends out on limb chirping away the hours.</p>
<p>In the spring and summer months, a high testosterone concentration is typical in many species and is known to increase singing and may also result in displays of territorial aggression (passerine). These same high levels of testosterone result in full-fledged &#8220;songs&#8221; rather than bits and pieces of melody. </p>
<p>As the seasons change and begin to cool off, not all species of birds migrate. Those species that stay behind tend to defend the same territory they used earlier for breeding. For example, Song Sparrows establish and defend winter territories which are maintained and defended by small groups of two or three individual birds made up of males and females.</p>
<p>So that singing you&#8217;re hearing on a cool crisp autumn day? Just the bird letting everyone know it&#8217;s going to be around for a while.</p>
