T. Cade 1959 Falcon rusticolus 21 May Pitnygea - one was seen to appear in the air on north side of the view and make a pass at a roughlegged hawk which revealed. The hawk continued forward the mouth of the view, but the falcon veered off and made a busy diagonal sweep below the brow of the spring on in the direction of the cliff where Childs found gaps building in '57 & '58. Size of the falcon relative to 4 rough-legs indicated it was a 3rd - darker grey in color. Later at a point up view, a falconous very at a distance up it swooped low over the cliff edge at a sitting short-eared owl. The owl flipped up and stuck out its feet so the falcon made its pass. 23 May Pitnygea - visited the area 2 miles up view on the right limit. It is very light bird - white on throat and upper breast, light grey on rest of ventre - very slight grey worn - somewhat darker - blue on rest of dorsal aspect - wings darker.
