Today while birding along the Maclay Irrigation Canal, just south of the Maclay Recreation Area near Missoula, Montana. Within the canal and keeping company with a pair of Wood Ducks was a pale-headed teal. Upon glassing the presumed teal, it seemed to be a Baikal Teal. I managed to fired off a volley of photos (see below). The Baikal Teal soon flushed with the Wood Ducks. It circled around and settled in an old, small gravel pit some 300 meters away. I pursued the bird to that location. The teal had settled in with several Mallards. More detail will be added to this posting as I complete the various write-ups of the sighting. Please use the comments on this post for information.
UPDATE: The Baikal Teal sighting was accepted by the Montana Bird Records Committee
