Calioris bairdii
8 May
Unless surfbirds also have a baird-
like rattle note, heard bairdii this afternoon.
9 May
Saw and heard more bairdii today.
they are widely spaced along the ridges.
Lots of short display bouts with rattle note,
but no sustained display.
22 May
Saw a flock of 7 feeding in a wet
gravel pit beside Steese Highway ca. mile 32.
23 May
More birds and more display activity
than previously, while other shorebirds
seemed down.
26 May
Birds are now extremely numerous
along the ridges and upland terraces.
they were displaying very actively today.
Saw both pairs and small groups of up
to 5. At least here low densities in the
mountains can not be blamed for Dixon's
daim that they are silent on the breeding
grounds.
28 May
More of the same. Birds are largely
paired. there is a fair amount of display, but
pairs are spaced out so that there is little
interaction between pairs. Still some small
groups moving in the area.
