Owl About Birdhouses

Did you know that most owls do not build a nest or gather any nest-lining materials? (The notable exceptions are the Short-eared Owl and the Snowy Owl, which build ground nests.) Most North American owls depend upon a cavity in a dead tree or broken-off trunk if they are cavity-nesters, or they repurpose the old nests of other raptors if they are platform nesters. Sometimes, an old barn or duck blind will fill the need. Building a nest box or nest platform for your local owls is a fun fall project that will outlast any jack-o'-lantern. Right now, pairs are searching for suitable nest cavities in advance of the breeding season and calling to establish territories.

Eastern and Western screech-owls are commonly found in suburban neighborhoods with some tall trees, and in large cities with urban parks. Barred, Northern Saw-whet, and Boreal owls choose mature woodlands for their nesting sites, preferably near water. Barn Owls nest in open habitats, similar to bluebirds, and often choose agricultural areas. Great Horned and Great Gray owls will accept basket-style nesting platforms placed in the forest interior. Use our Right Bird, Right House tool to find out which owls nest in your region and habitat, plus tips for attracting them to your box or platform.

Shh—Day Sleepers!
Scientists still know very little about the breeding habits of owls, and their nocturnal ways make them difficult to study. You can help by installing a nest cam in your owl box and reporting your data to NestWatch. A nest cam helps you keep tabs on the owls without disturbing them during the day when they're resting.

More California Nesting Data

Last month we told you about a massive data upload from the California Bluebird Recovery Program (CBRP), and mentioned that another 2,000+ nests were on the way. Well, they've arrived...2,129 nest records to be exact. These nest records come to us from Lee Pauser, an active member of the CBRP, and a volunteer for the Santa Clara Valley Audubon Society's Cavity Nesters Recovery Program. 

This recent addition to our bulk-imported data features 18 species and spans 14 years (that's 6,796 fledglings!), resulting in very good coverage of the San Francisco Bay area. Lee also works with the Wildlife Center of Silicon Valley to retrieve injured or abandoned Barn Owl nestlings for rehabilitation, and eventual release. (Severe droughts in the area can lead to starvation and nest abandonment.)

If you or someone you know has old nest records that have not been permanently archived elsewhere, inquire about whether our Bulk Import Tool can work for you.

New Project Builds NestWatch Curriculum

This month, NestWatch begins an exciting new project engaging youth in citizen science. With support from Smith-Lever Act funds, we'll be working in two Upstate New York communities to build, install, and monitor nest boxes with youth and their parents.

These youth workshops will be used as a model to create a national curriculum on nest-box stewardship and citizen science. The curriculum,  which we will be developing with help from our 4-H partners, will eventually be hosted online and available to any educator for free. Our goal is to introduce concepts of science and ecology focused on cavity-nesting birds to young people.

Give and You Shall Receive—a Free Webinar!

For a limited time, anyone who donates to support NestWatch will receive a free webinar on "Understanding Bird Behavior" from the Cornell Lab of Ornithology's distance learning program. This live, hour-long webinar will explore the world of bird behavior, looking at the subtle and not-so-subtle ways that birds communicate. You’ll learn to read a bit of bird body language and come away from the webinar with a new framework for understanding what birds might be “saying” and why.

The online training session is being offered on October 14 at 7:00 p.m. and 9:30 p.m. EST, and donors can pick which session they want to attend. A donation to NestWatch of any amount gets you a free seat in the class, a $12.99 value, plus other incentives at higher gift levels.

Don't wait! To take advantage of this offer, you must make a donation to NestWatch by October 13 using our online form, and indicate which time slot you'd like in the comments. We'll send you email instructions on how to join the class.

The Cornell Lab of Ornithology is a membership institution dedicated to interpreting and conserving the earth’s biological diversity through research, education, and citizen science focused on birds. Visit the Cornell Lab’s website at http://www.birds.cornell.edu

NestWatch is a citizen science program that tracks status and trends in the reproductive biology of birds, including when nesting occurs, number of eggs laid, how many eggs hatch, and how many hatchlings survive. To learn how you can help, visit NestWatch.org.
