The 2016 NestWatch Digest Is Here

When the breeding season comes to a close, the real work of analyzing your data begins. Every winter we comb through nesting attempts from across North America and tease out the season’s trends for different regions. Want to know if last year was a “good” year for nesting birds? Read the Digest’s Regional Roundups to find out.

This year’s Digest also takes a closer look at an unusual nesting discovery, a Dark-eyed Junco nesting in a nest box. Juncos typically nest near the ground. We also celebrate historic Eastern Phoebe records now archived in our database and consider the impact of human structures on phoebes’ nest site preferences. Plus, get the scoop about our student-led research on supplemental feeding. The 2016 NestWatch Digest combines our latest data analysis and must-read news! Check it out.


Get a Nesting Birds Shopping Tote

Celebrate spring with this sturdy tote from the Cornell Lab of Ornithology. The tote is illustrated by two talented Bartels Science Illustration Interns: Chloe Lam and Liz Clayton Fuller. Lam’s Western Bluebird family adorns one side of the bag, nesting in a tree cavity. The other side of the tote, illustrated by Fuller, features a pair of Northern Cardinals perched in a flowering shrub looking down on their clutch of speckled eggs. 

Make this tote yours with a $50 donation to NestWatch. In addition to the tote, you will receive our Common Nesting Birds and Cavity-Nesting Birds posters. This special offer is good through April 1, 2017. NestWatch is possible because of your generous support. Thank you! 


Providing Nesting Materials Safely

Birds’ nests are works of art, woven fibers and sculpted mud. Sometimes those gorgeous nests contain human-made materials such as cotton threads or plastic tinsel. Even your dog’s fur or a horse’s mane can be incorporated into a bird’s nest.

It is tempting to provide these easy-to-gather materials for birds; however, new evidence from wildlife rehabilitators suggests that caution is warranted when putting out nesting materials. Even fur and other seemingly innocuous materials can tangle and entrap adults and nestlings. In light of this new data, the Lab has recently revised its list of Dos and Don’ts for providing nesting materials to birds. Do your part and keep birds safe this nesting season! 

Do provide any combination of the following: dead twigs and leaves, dry grass (make sure the grass is chemical-free), feathers, plant fluff or down (e.g., cattail fluff, cottonwood down), moss, bark strips, and pine needles.

Don’t provide: plastic strips, tinsel, cellophane, aluminum foil, dryer lint, animal fur or hair (including human hair), yarn, felt, or bits of cloth.
