For seven years, Cornell University students diligently collected nesting data on two species of gulls in Maine. Recently this large data set has come home to roost in our NestWatch database via a generous bulk-upload contribution from Dr. David Bonter.
Climate models are predicting drier conditions and more persistent droughts in North America. Thanks to contributions from NestWatchers, scientists were recently able to conduct the first range-wide analysis on the effects of drought on Eastern Bluebird breeding success.
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.
Can pairing nest boxes to reduce competition have a downside? Researchers at Davidson College say yes, and that if you’d like to help out the smaller bird species in your area, it’s all about entrance hole size.
If you monitor bird nests, you’re probably pretty familiar with mites. Join us as we explore the different kinds of mites that inhabit birds and their nests, and discover how birds have evolved to fight back.
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.
Do Northern Flickers have a “hive mind” mentality? Or is their acoustic resemblance to a swarm of bees simply coincidence? Listen in, and decide for yourself!
We love to play “Guess whose nest?” and answer your burning nest questions. Sometimes, however, this takes a detour into non-avian species. Here are our top five participant finds.
A new study based on Ohio’s bluebirds and Tree Swallows sheds light on how future climate scenarios might impact nesting birds. It also takes a look at how birds might help mitigate crop pests in Ohio.
A study spanning a century of House Finch data suggests that as California’s springs get warmer, the birds are laying eggs earlier in the season. Read on to learn how researchers used our nest records to uncover the historic lives of House Finches.
