Many species that are currently common may stay that way, and some species will likely increase…and hopefully species besides House Sparrows , European Starlings , Rock Pigeons and Eurasian Collared-Doves , which those in North America know as the four avian horsemen of the apocalypse. Whats in it for birds?

All New World Quail are highly gregarious, typically found in coveys or flocks except during breeding season. These could be the beginning of the formation of coveys, post breeding season flocks that form when the chicks become independent at about three months old. The birds scatter, sometimes in different directions.

A lovely looking and distinctive sounding bird (so they say, I sadly have not seen one…yet), the Kirtland’s Warbler can only be found during its breeding season in Jack Pine forests 5 to 20 years old in the northern Lower Peninsula of Michigan. Previously, even researchers had problems getting access to nesting Kirtland’s Warblers.

The newest bird on the brink to capture her fertile imagination is the California Condor, on which she graciously shares her research and ruminations: Sometimes as a writer you recognize there’s been something overlooked in your midst—something quietly abiding. Their size doesn’t escape you. You think of turkey dressed in black.

If this was America, we might not be concerned because starlings are an invasive species, at least in North America. Researchers are wondering if the die-off might spread to other birds or even fish.

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.

The history of the Wild Turkey, the reduction to its original range, and its re-expansion and re-introduction, remains today unclear and in need of further research.
