    Does Supplemental Feeding Help Nesting Birds?

    NestWatchers have helped shed light on one of the most-asked questions of our participants: what are the biological consequences of providing extra food to birds? As is usually the case, results vary based on species.

  • Does One Person Really Make a Difference?

    Once in a while, NestWatchers document something that is seldom seen. That’s what happened when Jo Roberts of western Texas recorded the first known instance of a Scott’s Oriole reusing the same nest for years. Jo reminds us that even one person can make a difference in what is known about a species.

    Do Birds Use Scarecrows? On the Evolution of Snake Skin as Nest Material

    Humans use scarecrows to scare away birds, but do birds also use scare tactics to repel predators from their nests? Our latest research suggests that they do, and NestWatchers may have even witnessed it in action. Read on to find out how birds try to frighten away ghouls from the nest.

  • Two people install a nest box on a pole in a field. The pole has a stovepipe baffle.
    Coming Together for Birds: Scaling up conservation to the community level

    Building safe and healthy communities for both birds and people has never been more necessary, but it doesn’t happen by chance. It happens when we join forces to identify a need, pool resources to accomplish a goal, and communicate the successes—and challenges—with the broader community. Read our thoughts on how to scale up your NestWatching to the community level.

    Cold Snaps and Heat Waves Create Challenges for Nesting Birds

    Many songbirds are nesting earlier in spring because of warmer temperatures brought about by climate change. But the shift brings another danger that is especially deadly for nestlings: greater exposure to temperature variability in the form of cold snaps and heat waves. A new study from Cornell documents that such extremes result in more nest failures.

  • A female Tree Swallow perches at a tree hole nest entrance, in which 3 young can be seen begging for food.
    Chasing a Moving Target: When insects accelerate, birds must try to keep pace

    You’ve heard of getting your “omega-3s”, but did you know that birds need them too? According to new research utilizing NestWatch data, insect-eating birds may struggle to get their omega-3s under climate change. Read about how nutritional peaks (i.e., insect emergences) are changing in this new research summary.

    Buckeye Birds Track Temperature And Precipitation

    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.

  • Bluebirds And Fall Foliage Have Something In Common

    What do bluebirds and fall foliage have in common? It turns out, quite a lot! Our guest student blogger uses her artist’s eye to spot surprising similarities in nature that might otherwise go unnoticed.

    Avian Apothecaries

    Not only do humans self-medicate with aromatic herbs such as lavender, mint, and sage—it turns out that birds also utilize pungent plants in their nests.
