New World Vultures.

This lake, with a surface area of up to 150 square miles in good years, is my go-to site for dozens of waterfowl and shorebird species, so I take its health personally. It is also a vital wintering and migratory site for most of these species, so I imagine they take its health very personally, as well.

Reintroduction efforts expanded to Arizona in 1996, and later, to the Baja California peninsula in Mexico.

The warm, sunny climate beckons a wide variety of passerines, raptors, and shorebirds to spend the winter, inflating the species diversity to the extent that Miami-Dade can go toe-to-toe with counties in Texas and Arizona during this season. Can we hit 200 ABA-countable species in four days next year?
