Use a dichotomous key to identify Tern Island birds!
A dichotomous key asks you "yes or no" questions to traverse a decision tree until the answer is found. You'll be shown pictures of birds, and you can click on the one you want to identify to enter the key.
This key includes many of the birds found on Tern Island at French Frigate Shoals, which includes many birds found on the other NWHI as well.
