Witness the rufous hummingbird, which visits wildflower meadows and hummingbird feeders across the Colorado Plateau in late summer.</p><p>For a bird less than four inches in length, the rufous hummingbird pulls off an impressive migration each year. From their wintering grounds in southern Mexico, they fly north each spring to breeding territories in the Pacific Northwest, western Canada, and even as far north as Alaska.</p> Wed, 08 Aug 2012 11:00:00 +0000 Peter Frederici 18226 at http://knau.org Earth Notes: Summer’s Pugnacious Hummingbird
