Collectively, they’re referred to as the Herring Gull complex. It is also familiar at inland sites in winter, especially reservoirs and refuse tips, and breeds in the relatively-Northerly regions of Europe, Asia, and North America. This wiki looks good too.] The Lesser Black-backed gull has a dark grey to black back and wings.

If you have always wondered what the minimum anesthetic concentration for isoflurane and sevoflurane for the Crested Serpent-eagle is, science has an answer. The breeding ecology of the Yellow-bellied Warbler was actually studied exactly here at Nonggang in 2019 by 3 Chinese researchers. So you just have to look at the photos for once.

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. They portray the nesting cycles of Mallard, Red-tailed Hawk, and American Robin, illustrating the various ways in which birds create families.

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. Wait–that adds up to 290 species, but the book only covers 283. First page (p.

I am also writing it on the tails of an excellent review by Corey who, although he termed his post a collection of “impressions,” really did nail down the great content of The Sibley Guide to Birds, Second Edition , by David Allen Sibley, as well as the minor items that need to be improved. Goodbye “front-heavy appearance.”

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.

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.
