The feature distinguishes birds from other species; All birds have them, no other species do.

Here’s the thing.

That’s pretty amazing–Bolivia has more bird species than India! 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.

The book is divided into three parts: “Introduction,” “Avifaunal Overview,” and “Species Accounts.” Most birders will go straight to the “Species Accounts.” It’s important to note that the 301 species selected for this section are those of historical and current importance to the core study area, the northwest Bronx.

Every time a gene is replicated, or really, a chromosome (during cell division), a bit of the end of a gene may be lost, owing to the way this process happens. This is part of the process of aging.

The vast majority of the 10,000+ living species of birds are passerines, and the vast majority of those have a similar system of breeding: Mom and dad bird make a nest and share parental responsibilities roughly equally, if not identically. Our field data suggest that a two-way process underpins this relationship.

They are generally cryptic species and despite frequent extended bouts of calling, their ventriloquial skills make them tricky to locate. Benson to collect birds.
