A breeding bird atlas is a special kind of book. For birders, it’s the extremely large book, shelved in a place where it can’t crush the field guides, used to research the history of a bird in their area. So, what exactly does a breeding bird atlas contain? The resulting book, 616 pages in length, 6.4

Even though the female lays only two eggs per nest attempt, they enjoy a protracted breeding season in which multiple nesting attempts can occur every 30 days, and in Southern locations, nearly year round. With all the research that has been done on lead vs non-lead bullets, there is no reason for ANYONE to use lead when hunting.

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.

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.
