Holmes,R 1964 C. fuscicollis 17 12 June Barrow, Alaska + was of the same state / condition - ie just a scraped cavity with mucus - or a few bits of debris The first two sequences took place about 10 min. apart - about 5 min. after #3. At the same bird was flown to the display again. 30' south #2 - it just settled momentarily into the cup, tossed for a few seconds (with the terminal backing out of the cup). Scrape was as other - 2 cup with bottom scraped clear - for prey? when - grass at edge Cups were matched - xi probably by the bird rotating - the cup. - After bird left cup - we flipped up shores at 45' for 20 sec - then flipped down - set wings. - Boundary conflict recorded per round drums - One bird went up to 36' - scaled form - set wings back, folded wings - flushed wing. Almost simultaneous - second bird was doing the same thing - loaded sun bark about 4' apart (only bird did the wing flip - as in our self). - both went into - lumbered, back feather-ruffled, tail depressed & spread pattern as they faced each other - for about 20 sec - then both flushed toward our area - east four - haven display -
