Many bird species across the world have been placed under protection, as the importance of conserving them has become necessary. Due to their declining numbers, ornithologist have been submitting requests for at least seventy species to be noted in the Endangered Species Act since the 1980s. These species were submitted from all over the world, and the United States Fish and Wildlife Service confirmed that most of these bird species submitted would come under the Endangered Species Act. Now six foreign bird species have been entered onto this database.
Sometimes the daily habits of a certain bird species may be so obscure that ornithologists are not even sure how many of them exist. That certainly seems to be the case with the Slender-billed Curlew as it seems there is some doubt as to whether or not this bird is still surviving or has become completely extinct.
Sandpipers are familiar to most birdwatchers. Yet their identification can be very frustrating. Most sandpipers are feathered in browns or soft grays, and gather in flocks that contain many species. Some are distinctively patterned, but others are so similar even experienced birders have trouble identifying them.
