Empidonax hammondii
The Hammond's Flycatcher lives higher in the mountains than other Empidonax flycatchers, commonly nesting up to 10,000 ft. (3000 m) in the Rockies. It tends to prefer conifer stands greater than 20 acres (8 ha) in size and at least 80 years of age. Because of modern forestry practices, logging might affect the stability of this species's populations, and it might become increasingly dependent on our national parks for habitat preservation. Empidonax is a wonderful name for these confusing, but endearing, birds-it means 'lord of the mosquitoes.' William Hammond, after whom this Empid is named, was an army surgeon who sent animal specimens from western North America to the Smithsonian Institution. |
