Capt. Lewis, August 1, 1805--I also saw at the top of the mountain among some scattering pine a blue bird about the size of a common robin. its action and form is somewhat that of the jay bird and never rests long in any one position but constantly flying or hoping from sprey to sprey. I shot at one of them but missed it. their note is loud and frequently repeated both flying and when at rest and is a char-ah, char-ah, char-ah, as nearly as letters can express it.
