The endangered Golden-cheeked Warbler breeds only in Texas Hill Country near Austin and San Antonio, but much of its nesting grounds have cleared in favor of subdivisions.

While we continue to decimate our short and tall grass prairies many species reach their inevitable peril. Here in Colorado many species are affected, but perhaps none more than our beautiful Mountain Plovers and Ferruginous Hawks.

” Writing about owls means writing about roughly 250 species (I counted 245 on the 2022 Clements spreadsheet, but I might have missed a few, and we all know that each classification system is different). The chapters on courtship and breeding and roosting and migration are the longest, which isn’t surprising.

As part of the Wildlife Conservation Society Birds of Brazil giveaway we asked readers of 10,000 Birds to name the bird in Brazil that they would like to see more than any other species. What follows are the responses that readers offered, a veritable aviary of sought after species. It is a really neat bird that I have not seen before.

Court of Appeals for the Ninth Circuit recently decided that the Sonoran Desert population of Bald Eagle is not a listable taxon under the Endangered Species Act.
