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

Well-researched and footnoted, these sections never feel disconnected from the more personal sections.

With populations plunging dramatically over the last decade, researchers from the Wildfowl and Wetlands Trust, Birds Russia, and a number of other conservation organizations made the always-controversial call to pluck eggs from the imperiled wild population and establish a captive breeding program as a final hedge against extinction.

The nickel was placed in the nest for the photo to show me the size of the egg for identification purposes, then removed. 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.

According to the HBW, when breeding, male birds do most of the incubation and parenting while females often leave the nest up to one week before the eggs hatch. According to Couzens, after laying the eggs, females sometimes immediately abandon their first mate and pair up with another male. How efficient. How surprising.

A study on the breeding biology of Whitehead’s Broadbill was just published in May 2023 but leaves a bit of a puzzle as the breeding success is described as relatively high, meaning there should be other reasons for the population decline of the species. That might help these species deal with climate change.
