Interesting. Today I observed a Red-Tailed Hawk hovering in a stiff breeze. The Rough-Legged Hawk is well known for this, but, to my mind, nothing matches Falco spaverius, the American Kestrel ( should be called the Sparrow Falcon IMHO ) for hovering dead still in turbulent and extremely gusty wind conditions. Hummingbird, Schmumingbird. DV
