Flycatcher Competition

Jordan Lake: the lake hosts several species of flycatchers. In these photos you see two of them: a Tree Swallow on the left and a Great Crested Flycatcher on the right. Both of these species are cavity-nest breeders and will compete for the same abandoned woodpecker nest cavities. Both species also compete for the same flying insects. In the first photo the great crested flycatcher has nesting materials in its beak. There was a lot of competition for who got the best cavity for their nest … ultimately they both used the same tree with their nest cavities about 90degrees and 8 feet apart.
