Falco columbarius
Like the sorcerer of King Arthur's court, the male Merlin wears a dapper blue cape on his back. The main weapons of this small falcon-like all its falcon relatives-are speed, topography and surprise. Their sleek body design, long, narrow tail and pointed wings maximize speed. Merlins tend to hunt small songbirds, and individual Merlins are known to concentrate their activities on one or two species. Through the fall migration, Merlins may follow larks and pipits south through high alpine meadows. The scientific name columbarius is from the Latin for 'dove' or 'pigeon,' which the Merlin resembles in flight-it was formerly known as the Pigeon Hawk. |
