Most predator guards that prevent climbing predators are built for nest boxes that are mounted on poles. New research supports the effectiveness of a simple DIY predator guard meant to deter snakes from tree-mounted boxes.

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.

Recent research reveals that a strategy thought to reduce ectoparasites may not have the presumed benefits some nest box landlords expect. According to the new study, replacing nest materials infested with parasites is not a recommended practice due to its lack of benefits and potential for stressing nestlings.

A new study from NestWatch investigated how many people had experience with non-native birds in their nest boxes. The study explored peoples’ knowledge of House Sparrows and European Starlings, and their attitudes towards managing them, especially if people encountered these non-native birds in their monitored nest boxes.

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.

When Pygmy Nuthatches were creating a nuisance in a Colorado community, one woman stepped in to advocate for a peaceful solution. That act of peace eventually changed the arc of her life—taking her from occasional birder to self-taught citizen scientist and community activist.

This month, we’re highlighting students as FORCES for good. A unique program in the Finger Lakes, Niagara, and Central regions of New York called “Friends of Recreation, Conservation and Environmental Stewardship” (FORCES) is engaging college students to improve state park offerings. NestWatch is among the lineup of hands-on opportunities that are available to college students to help them gain career-related experience while also benefiting their local state parks.

A unique new study combines American Kestrel nest records from varied sources in order to analyze trends in nesting phenology. What they found is that for kestrels, especially those in the Northeast, it pays off to be right on time. Delays in starting a nest resulted in fewer offspring and lowered probability of success.

This year we’re asking NestWatchers to accept our challenge to find one nest of a species you’ve never monitored before. For inspiration, we illustrated five beloved backyard birds that nest near people. Download and print the images as a reminder, and read on to learn how to find the nests of these “outside the box” nesters.
