An associated issue is that the Belize and Costa Rica guides share many of the same descriptions of species, written by Howell. Similarly, descriptions of species repeated across volumes do not lose their accuracy with each publication. Other species are splits and lumped and have had their names changed. Why are these issues?

Such programs are somewhat inefficient anyway – in one study , the breeding success of wild male pheasants was 2-5 times higher than for hand-reared and released ones while for females, hand-reared birds were 3 times as vulnerable to predation as the wild ones. Apparently, there is a website just showing stamps depicting bird species.

If I was an ornithologist aiming for a grant, I would now definitely highlight the need for more research on this topic. The Grey-Streaked Flycatcher looks only marginally more interesting, and while the Latin species name griseisticta sounds vaguely mysterious, it only means grey-spotted.

The feature distinguishes birds from other species; All birds have them, no other species do. Beaks vary across different kinds of birds, and this great diversity in beaks is part of the great diversity of the 10,000+ species of birds that exist today; Beaks thus facilitated the diversification of birds. So how did beaks evolve?

It’s not often that we have the opportunity to glimpse the home life of albatrosses, nor of any seabird species. We didn’t know much about migration routes, foraging away from the breeding colony, and feeding during migration, in the water and in the air. Technology to the rescue!

Plasticity in humans is probably modulated primarily through experience and enculturation. 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. My research in the Congo supports this idea.

In the Old World, Horned (Slavonian) Grebe breeds in a wide belt stretching from Scandinavia to Kamchatka and it spends winters along sea coasts, from Japan to China and from Norway to France, plus the Adriatic and the Black Sea (west and east of the Balkans, respectively). As a consequence, this species is only a rare vagrant in Serbia.

This is similar to the fact that all birds, even first time breeders within a species build identical nests. Further support for inherent behavior comes from experiments. In another experiment, other species of Darwin Finches were kept next to Woodpecker Finches that used tools. The behavior was inherent.

All species are from the ABA area, and all groups must meet at least one of these criteria: (1) the group “represented a good opportunity to build core birding skills,” (2) the authors thought it was a group that needed “a refreshed treatment,” (3) the authors were intrigued by the group and wanted to present it using their unique format.
