10,000 Birds

The last time I visited Portola was in the summer of 2011 when the Swainson’s Hawks ( Buteo swainsoni ) were nesting there. They are listed as a Species of Special Concern in Utah, Nevada, Oregon, and Washington, and as Threatened in California. This is the painting of the species by John James Audubon in the early 1800′s.

Pough “with illustrations in color of every species” by Don Eckelberry, Doubleday, 1946. The National Audubon Society Birds of North America covers all species seen in mainland United States, Canada and Baja California. The press material says it covers over 800 species, so you know I had to do a count.

This thrush is extremely common in urban and suburban Germany and one of the most conspicuous bird species here, comparable to the American Robin in North America. Because this was such a common species, we lacked quantitative data to be certain that this lack was an actual “situation” and not just the ordinary seasonal variation.

Greater Rheas, a species the Germans call Nandu, are very popular in Germany and frequently kept in zoos as well as private enclosures. On the contrary, the birds were quite satisfied with their new-found freedom and realms, and started breeding immediately after their escape in the spring of 2001, much to everyone’s surprise.

The clifftop habitats along rocky shores of the North Atlantic (on both sides of the pond) abound in bird biomass during breeding bouts, for instance. Those mammals consist of the previously mentioned fossorial members of Insectivora, Rodents, and bats. Accessed July 12, 2011 at [link] a. Sources Laden, Greg. Myers, P.,
