I’ve arranged the birds by habitats. In breeding season, their habitat is where they nest; in non-breeding season or in migration, it’s where they find food. For example, downy woodpeckers nest in tree cavities and therefore require a woodland habitat; in winter, however, they may come to your backyard feeder. I’ve also grouped the birds into categories, such as shorebirds, wading birds, raptors, etc., and within each category listed them alphabetically by common name, usually the second part of the name, such as plover, sandpiper, turnstone, willet, etc. The captions give the bird’s common name, Latin name, date and place of observation, and status. I use the data from Cornell’s excellent site, All About Birds.
