Black-capped Chickadees do not breed on our property. The Chestnut-back Chickadees take control of all the nest boxes.

They are particularly fond of peanut butter cakes but also enjoy suet cakes and black-oil sunflower seeds.

Researchers have documented 1,500 Black-capped Chickadees with bill deformities in south-central Alaska along with 19 other species of bill deformities. Although environmental contaminants are on the list of possibilities, they have not yet established any causal links. For more information and what you can do to help, read their article on Beak Deformities.
