Behavior Station
Nov 17 (cont'd) another flock flew in, composed
of about 7 birds -- mostly bright
red males. Again, Type 3 calls by
the entire flock -- now from
this flock were captured. The last
crossbills seen today were some
Type 4 (the V-shaped calls)... 3 birds,
I think 1 ♂ and 2♀ came around,
and I recorded the ♂ on tape 45
but none of the 3 were captured
or shot. They looked small. Also,
today a sharp-shinned hawk attacked
caged birds -- but none gave
alarm calls. Also seen was a varied
thrush. Birds 280, 281, 283, and 284
were killed after tape recording today.
Nov 18 Up at ABS again today, with "57"
and 282 and 285. 57 gave some
good calls, toops, alarms, and song --
all her usual Type 1 (except the flight
calls). 282 and 285 were tape
recorded and killed. No wild crossbills
were heard or seen today. Pine siskins
were abundant again. Saw a flock
of waxwings with robins.
