Organized by the Mesoamerican Ecotourism Alliance, the Yucatan Birding Festival offers birders the opportunity to view the birds of the Celestun Biosphere Reserve. Home to the American Flamingo and more than 300 bird species (resident, migratory and endemic), the reserve boasts tropical forest, sand dune vegetation and mangrove forest habitats.

The Western Grebe (Aechmophorus occidentalis) moves in large flocks and is found across the American western region and Mexico in the summer, migrating towards the Pacific Coast and Southwestern waters for winter. Both the males and females look similar, with black crowns, back, wings, nape and face. They have white plumage on their necks, throats and bellies, and have red eyes and bills that are a green-yellow color.
Being water birds, the Western Grebe can be found close to the seashore, freshwater lakes, ponds and swamp areas. They generally feed on fish, which is speared with their bills, but also eats crustaceans and insects. During the breeding season, both the male and female Grebe will assisting in building a nest that floats and is constructed from plant materials that are anchored to plants emerging above the shallow water. The female Grebe will lay three or four eggs, and both parents will take care of the eggs during the incubation period. The incubation period for the Western Grebe is 23 to 24 days. The eggs are a blue-white color and the male and female Grebes both feed the chicks after they have hatched. The Western Grebe, and the Clarke’ Grebe, population numbers were dwindling dangerously low, due to being hunted for their feathers. However, conservationists have been working to protect these species and the numbers have slowly been recovering. These birds are very sensitive during the breeding season, and if humans come too close to the nest, they will abandon the nest, leaving the eggs completely exposed to dangers.
The Western Grebe has one of the most amazing and spectacular mating dances – very elaborate and extremely entertaining. Both the male and female Grebes will lift their chests above the water and move together while gently letting the vegetation that they have in their bills, run over one another. The mating pair will then look at one another, before they suddenly leap from the water and run across the surface with wings outstretched and necks held rigid, before diving head first into the water together.
Considered by many to be the most beautiful of all waterfowl, the colorful Wood Duck (Aix sponsa) is somewhat unique in that it is one of the few North American ducks that nest in trees. Also known as the Carolina Duck, the Wood Duck can be found in eastern North America and the west coast of the US, as well as in western Mexico. They usually select wooded swamps, marshes, ponds or shallow lakes as a breeding habitat and will nest in tree cavities close to water. Despite their popularity, these birds are shy and skittish and they are quick to make an escape if disturbed or threatened.
The average Wood Duck is 47-54 cm in length with a wingspan of 66-73 cm. This makes them a medium-sized duck with long, broad wings. They also have a crest on their heads and a long tail. The male is most spectacular during breeding season. Between fall and summer he has a red bill, red eye and green head with striking white stripes around his face and chest. These stripes start as a white throat patch which then grow into ‘finger-like’ extensions which can be found at the base of the neck and the bottom of the cheek. His breast becomes a strong chestnut colour and there is a white vertical strip at the lower margin. His flanks are a golden colour which are bordered at the top with a white flank stripe. His belly is also white and his wings and back become a shiny dark green-blue. There is also an iridescent blue-green speculum on the rear of his wings with a white edge. When he is not breeding, the male looks quite similar to the female, except that he retains his distinctive white neck patch and red bill. The adult female is much less colourful and has a grey bill, a white teardrop patch around her eye and a white throat. Her head and neck are a grey-brown colour and her grey-brown breast is stippled with white which fades into a white belly. Her back and wings are a dark brown.
Generally speaking, the Wood Duck eats seeds, acorns, fruit and both aquatic and terrestrial invertebrates. They peck and dabble on the surface of the water and may dive under for food. When they nest, they may make use of nesting boxes if these are available. The nest is lined with down from the female and she lays between 6 and 15 eggs in a clutch. Soon after hatching, the down-covered ducklings jump out the nest and make their way to the water where they put their natural swimming talent to good use.
Known for their beautiful songs Wood Thrushes (Hylocichla mustelina) are more often heard than seen. These delightful birds are a medium-sized thrush and are the only member of the genus Hylocichla. They are migratory, and while their breeding grounds are in eastern North America, they generally fly south at night in mid-August. They may stop on the Gulf Coast for a few days in inclement weather before attempting to fly across the Gulf of Mexico to the tropical forests of southern Mexico and Central America. Wood Thrushes have been found in Western Europe but this is a rare occurrence and these birds are usually vagrants.
The typical Wood Thrush is 18.5 cm long and weighs about 48 grams. Their crowns, napes and upper back are a rusty-brown colour while their underparts are white with random black or dark-brown spotting. The rest of their upperparts are brown and they have a white eye ring and streaked cheeks. The bill is short and pointed with pink colouration near the corners and black colouration on the tip. The legs are also pink. All in all it is quite an attractive bird and both sexes are similar in appearance. The juvenile bird has pale spots on its upperparts but is otherwise difficult to distinguish from the adult. Wood Thrushes are famous for their beautiful flute-like voices and they are capable of combining two notes at once. Their singing is usually stronger and more elaborate just before sunrise and at dusk though they may sing throughout the day during mating season. They usually stop singing by the end of July.
Wood Thrushes generally favour well-shaded areas near water. They feed on beetles, flies, millipedes, earthworms, spiders and sow bugs which they usually find by overturning fallen leaves on the moist soil. They also feed on small fruits and berries. In the springtime, males return to their breeding grounds early to establish their territories. Before long, their beautiful songs attract a mate and a nesting sight that is well concealed and has plenty of shade is chosen. The female will usually build the nest in a fork in a tree, using mud, dead grass and dead leaves to create the structure. Once the nest is built, she will lay 3-4 greenish-blue eggs in it which she will incubate herself. She may have two broods in one season. Once the Wood Thrush chicks are hatched, both parents help to feed the nestlings.
