Very simply put, the bird population in the Mohave is in the process of collapse, and the reason for it appears to be climate change. Sites lost on average 43% of their species, and occupancy probability declined significantly for 39 of 135 breeding birds. More recently, Kelly J. Iknayan and Steven R.

After writing this last sentence, I looked up the species in the HBW and found the sentence “Song poorly documented” in the appropriate section, while with regard to calls, the description is that “call is a two-note raspy nasal ‘ryeeh-reh’”. It is even better to see adult Striated Herons in the wild, at Nanhui.

The source of this ranking, BirdLife International, lists Bolivia as currently having 1,439 bird species, including 18 breeding endemics. The guide covers 1,433 species, the number of birds documented at the end of 2014, the cutoff point for the book. That’s pretty amazing–Bolivia has more bird species than India!

Most likely, all individuals of a given species have very similar genes guiding very similar developmental processes, but produce different results because the plasticity itself is selected for. Part of that research was to document human avoidance by ground mammals, and that was stark and apparent. Clearly, more research is needed!

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. Wright emphasizes the use of “shape and pattern of wing and tail” and size in the identification process. Range and Geographic Variation.

It’s the process of using knowledge of natural history, habitat, distribution, behavior, and, yes, taxonomy, combined with specifics of adult and juvenile plumage and vocalization to identify a bird, often to the subspecies. The process is called “Wide-angle birding: Be the bird, see the bird.”.

Unlike most field guides, the maps are large and specific, indicating permanent, winter, and summer ranges by color swatch; summer, winter, and all seasons dispersal routes by colored lines, and irregular breeding sites by shape and color. A simple listing of species and page numbers would have facilitated this process.

What the Owl Knows is organized into nine chapters: introduction, adaptation (including vision and flight), research and researchers, vocalization, courtship and breeding, roosting and migration, cognition, and two chapters on owls and humans–captive owls (not zoos, educational owls) and owls in our cultural history.

The basic premise is that observation of traits such as size, shape, structure, and behavior, the same traits Dunne writes about in his hawk books, could and should be used as the basic blocks of a ‘holistic’ identification process. The process doesn’t totally ignore plumage. These vary according to species.

The authors make clear that the discovery, identification, and description of damselflies and dragonflies in Costa Rica is ongoing and in process and there are several species that have yet to be scientifically described and added to the official checklist. .* Wait–that adds up to 290 species, but the book only covers 283.

and it breeds in the scrublands of Texas, Oklahoma, and northern Mexico. Fortunately, the process by which a species is delisted is actually quite transparent: anyone with internet access can review exactly what FWS proposes and precisely the scientific evidence FWS says supports the proposal. All of the comments are here.

The auk identification process is pretty straightforward. The following section encapsulates a chapter of biological facts into one dense paragraph–breeding location, breeding time of year, nesting notes, timing of fledging, migratory routes to and from breeding areas, staging locations, foraging locations, and more.
