These flycatchers built a nest just outside Alex’s remote research cabin. Luckily for him, they were the very species he wanted to study. So as not to disturb the birds or attract predators, the biologist hid his camera behind a large piece of bark on a nearby tree. He directed a flash towards the trunk, operating the set-up from inside.
The Cordilleran flycatcher chicks pictured were about 12 days old. Although this species is widespread across North America, numbers are declining. In arid western areas, rising temperatures are drying up rivers and other freshwater corridors along the bird’s migratory routes and in its wintering grounds in Mexico.
