How did the bizarre folklore of the “changeling” child first enter European literature? Could an avian reproductive strategy called “brood parasitism” have served as inspiration? This week, we explore the origins of this fanciful myth by examining real-life changelings (i.e., cowbirds and cuckoos).

The North American Bluebird Society recently convened a virtual conference to assess the status of the least-studied bluebird species—the Mountain Bluebird. Four panelists looked at trends and interacted with nest box stewards to try and understand what next steps would help address declines.

Nest box monitors in Florida and Texas have reported some extremely early Eastern Bluebird nests this month. Learn more about this exceptionally rare timing, and what may have triggered these unusual nesting attempts.

Whether for camouflage or parasite reduction, or due to cold weather or nest site competition, not building a nest can certainly have its perks. Meet five species that skip nest building.

She may not be old enough to drive yet, but 14-year-old Katelyn Shelton didn’t let that stop her from creating a nest box trail in her neighborhood. A contributor to NestWatch, Katelyn shares her enthusiasm for birds and conservation as a guest blogger.

House Finches are known to nest around human habitations, but are only rarely documented using nest boxes. We spoke to two NestWatchers who have House Finches using nest boxes they monitor, and we share tips on what to look for if you think you might have them, too!

A NestWatcher discovers an albino Tree Swallow in a Massachusetts nest box. Fewer than one-half of a percent of all birds have this genetic condition.

The latest research paper to include NestWatch data is not your average avian study. Your data contributions were recently put to use in an examination of gray ratsnake climbing behavior. The study authors were interested in which factors correlate with ratsnake climbing forays, and they wondered if the timing of nests (and thus a seasonal abundance of eggs and nestlings) was an influence.

In New York City, citizen scientists help urban hawks by contributing nest observations to the raptor nest monitoring project administered by NYC Parks’ Wildlife Unit. By contributing to NestWatch, these volunteers are helping to reduce secondary poisoning of birds of prey.
