P.D. Bevenditss A25 Calidius fuscitollis 19 June Barrow, Alaska - Three times and flew on. now apparently out of audible range; it was seen to glide once more + then the two flew a little faster and landed. Saw one brief interactive between this species and C. pusillus, but not sure who was after who. A female prepared in the evening had fat along all the feather tracts and considerable fat along the neck and axillary region. The skull was unossified and the skull windows measured 10x11 mm. The base of the lower mandible wool light colored, and it showed no signs of wear. 20 June Only two silent birds in this above area, all feeding in north west areas. 21 June No sign of the species in the area above. 23 June a pair found behind the micronic area in a low polygonized area. They fed in rather wet areas. Heard a flight call (but didn't see the birds until they were quiet), which sounded like "wo woitup woitup woitup" high pitched and buzzy and given rapidly. Later a single bird in flight went into a wing out glide, tail slightly spread and raised then it flew on with a hopping flight and landed near a 2nd bird and went immediately into a partial nest cup display, its breast down to the ground, its wings out
