At NestWatch we are often asked what materials birds use to build their nests. A recent study in Ohio focused upon the construction of Carolina Chickadee nests.

The most commonly used species typically were those that anchor tightly to tree bark and are known to cause skin rashes when touched by humans.
It is theorized that even though these particular species are difficult for chickadees to harvest, they are specifically selected because they produce an irritating chemical that repels nest parasites, although further research is required to confirm this.
