The source of this ranking, BirdLife International, lists Bolivia as currently having 1,439 bird species, including 18 breeding endemics. This is more than eBird reports–a checklist generated from the citizen science database lists only 1,413 species. Clearly, this is an under-birded country. . Van Remsen, Jr.

The Telomere does not contain useful genetic information, but rater, acts as a buffer. They used Great T**s from non-urban and urban areas, and mixed them up through breeding, to rule out any possible family history of telomere length. Telomeres are repetitive sequences of genetic material sitting at the ends of genes.

In a world of owl books (over 150 titles not including children’s books), Scott Weidensaul has written an authoritative, beautifully illustrated reference guide, that will be essential to any birder or naturalist who wants to go beyond the basic information in your field guide or handbook. It is not that kind of reference guide.

Scientists were largely limited to studies birds in breeding colonies, at least those we knew about and that were accessible (and, if you think that’s a complete list, you haven’t read the news that came out this week about a new colony of Adélie penguins found in the Danger Islands, Antarctica). Technology to the rescue!

Most likely, the researchers have indicated, the hatched birds would be viable and not too different from regular chickens, possibly less different than some of the odd breeds generated by more traditional methods. See: Four Wings Good Two Wings Better? So how did beaks evolve? Well, maybe a little better than that but not much.

As you can easily judge from the dullness of this information, it is not something I made up but rather an appalling example of nepotism in the naming of birds. If you have always wondered what the minimum anesthetic concentration for isoflurane and sevoflurane for the Crested Serpent-eagle is, science has an answer.

This is a delightful book, large (8-1/2 by 11 inches), filled with Sibley’s distinctive artwork and an organized potpourri of research-based stories about the science behind bird’s lives. The text is divided into three parts, informational stories or ‘essays’ as Sibley calls them.

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. …because cooperative breeding facilitates defense against brood parasites.

Their taxonomic affinities have caused great confusion and debate amongst ornithologists; they were originally assigned to the thrush family, then Old World warblers before being shifted to babblers (the last mentioned a common dumping-ground for any aberrant passerines).

The material on habitat tells us that sometimes looking for odonates in the tropics means thinking outside the North American box: Bromeliads and water-holding tree holes are breeding locations for certain species, including Blue-winged Helicopter.

Of the Central Flyway states, Nebraska alone holds out in protecting the cranes, having proven by its longstanding Festival of the Cranes in Kearney that a crane is worth infinitely more alive and purring in the sky with its family than thudding, broken and bleeding, into a cornfield. Additionally, sandhill cranes reproduce very slowly.

Another 170 are in captivity, many of them breeding stock for reintroduction efforts. My friend Vickie Henderson , who has some serious long-range vision, looked at the science behind Tennessee’s crane hunting proposal and found it badly wanting. There are 400 whooping cranes left in the wild, 100 of them in the eastern population.

Penguins are also bellweathers of climate change; dwellers of remote areas you’ve (probably) never heard of; creatures who have developed unique, innovative ways of adapting to the harsh environments where they breed and rear chicks and the water environments in which they feed and swim. And that’s just the top section!

And I found this one because he was singing his heart out quite persistently, which certainly suggests a bird that wants to settle down and raise a family. So yes, this appears to be a breeding population.]. And since I don’t go to the lake very often in late spring, I rarely get to see these Avocets in their breeding plumage.

Describing gull plumage is a combination of science, graphic art, and visual metaphor. I suppose this works with such a small family, but it made my librarian brain ache just a little bit. Distribution maps, ranging in size from one-eight to one-half of a page, indicate breeding and non-breeding habitats and trace migration routes.
