The newest bird on the brink to capture her fertile imagination is the California Condor, on which she graciously shares her research and ruminations: Sometimes as a writer you recognize there’s been something overlooked in your midst—something quietly abiding. Condors, like all New World vultures, can disturb the human psyche.

I even managed to shoot a video with hands trembling of excitement, probably a first of the species. Tommy Thompson Park Bird Research Station in Toronto had an extremely rare and beautiful Townsend’s Warbler x Black-throated Gray Warbler which was banded in April. Then we watched an adult and a chick feeding along the poolside.

Having that in mind, it is no small miracle that Colombia still has 1965 bird species left to be covered by this guide – more than any other country in the world. Among them are 94 endemics and 101 near-endemics, 4 introduced species and only 42 vagrants. Neither have I.)

At the recent Swarovski Social Media Summit in Arizona, Nate proselytized passionately for the program that both manages your sightings and contributes them to science. His exhortations fell on deaf ears, but once he shared all of our Arizona lists with me, I was hooked! But Nate is an eBird fanatic.

Write the authors: Near the border of Utah and Arizona there is a transition to a second, deeply divergent mitochondrial DNA clade (Brelsford et al. So what does all this mean — if anything — for how the birds are split or lumped at the species level? I think it’s unlikely that the Toews et al.

Note the long yellow gape, a characteristic field mark of this species. Ferruginous Hawks were petitioned for listing under the federal Endangered Species Act in 1991 but rejected; currently they are listed as a Category 2 Species by the U.S. Obviously more research needs to be done on this magnificent raptor.

Once considered a separate species, the Mexican Duck was lumped with Mallard in 1983 after studies indicated a high degree of hybridization, and that is where it’s remained ever since. And while we’re at it, what’s your experience with Mexican Ducks and Mallards in Mexico, Arizona, New Mexico, and Texas?

For birders, it’s the extremely large book, shelved in a place where it can’t crush the field guides, used to research the history of a bird in their area. You can see the Species Account for Henslow’s Sparrow above, in the banner photo. A breeding bird atlas is a special kind of book. The second page is the map page.

One might assume that construction of a border wall through a sensitive national wildlife refuge would be prevented, or at least slowed, by a thicket of lawsuits under statutes such as the National Environmental Policy Act (NEPA) and the Endangered Species Act (ESA).

I like observing them, reading about them, grappling with species and subspecies identification, and even—on a good day—talking about sparrow taxonomy. Peterson Reference Guide to Sparrows of North America covers 61 species of the New World sparrow family Passerellidae that breed in Canada, the United States, and northern Mexico.
