Calliope and Anna’s Male Hummingbirds at the Feeder

10,000 Birds

The Calliope Hummingbird is the smallest North American breeding bird 1. The males arrive on breeding grounds before the females and, according to their range map, they probably breed here in Shasta County. This is around the time of year I expect to start seeing the Calliope Hummingbird ( Selasphorus calliope ) at my feeders.

How The Bird Got Its Beak

10,000 Birds

Similar comparisons can be made with other bird features such as how their hips work. So this new research is very interesting, and we applaud the scientists for their work. These researchers carried out two different major efforts that in combination advance our understanding of the evolution of the bird beak.

10,000 Birds

For example, years ago, Eiton Tchenrov postulated that the wild progenitor of the domestic dog, some subspecies or another of wolf, could benefit from overlapping its breeding territory with human hunters. Previous research has shown that wading bird nesting colonies could provide substantial food for alligators in the form of dropped chicks.

A Field Guide to the Wildlife of South Georgia: A Book Review by a Penguin Groupie

10,000 Birds

The length of each bird species account varies, depending on whether the bird is native or a “visitor” (the book’s term for migrant) or vagrant, breeding or non breeding. They breed in dense colonies, incubate their single egg on the feet, and take more than a year to fledge a chick.

Do birds avoid predators because of culture?

10,000 Birds

My research in the Congo supports this idea. I spent a lot of time with Efe Pygmy hunters in the deep forest, and I spent a certain amount of time either entirely alone or with only one other researcher, this or that American. Part of that research was to document human avoidance by ground mammals, and that was stark and apparent.
