One of my absolute favourite bird calls is listening to the Eastern Whip-poor-will, early evening, on a quiet spring night. Eastern Whip-poor-wills are easy to hear but hard to see. Their plumage blends perfectly with the gray-brown leaf litter of the open forests where they breed and roost.
It’s also fun to watch them sally out from perches to sweep up insects in their cavernous mouths.
Eastern and Mexican Whip-poor-wills used to be considered one species, simply called the Whip-poor-will. But in 2010 they were split into two species based on differences in mitochondrial and nuclear DNA. Eastern Whip-poor-wills give faster, higher-pitched whip-poor-will calls and have more colorful eggs than their western counterparts. Cornell All About Birds
