(28 Jun) Flies to the back side, then flies to the high W
hole. I walk around and an adult ♀ has her
head out. Is this the victim. I searched For
the impact site (For painted rump Feathers) but
Found nothing at all. My guess is the hawk took
advantage of my distracting the birds and hit
one. I don't think they knew it was coming
because I noticed a bluebird acting rather normally
(and heard other birds) after (just) the scream.
The scream lasted about 1-2 seconds and stopped.
The hawk fled @ 10 sec later. Why did the Acw
stop screaming? If the intent was to draw a
predator to the predator, it worked - but why
did it stop screaming? (Screams are to startle the pred-
work, all screaming would accomplish is to make the hawk squeeze
harder.)
5 July 1400 Bird at mystery gran Flew to KOUT.
30 Sept D645-0830 Census: 1127, 1219, 1221, 1382, 1016,
1669 (the 1 that I saw a LB), 1670 (that sure was
stupid to give her the same bands as J1587), and
2 LB-KY R-LB (I suppose this is 706). These
birds are spending an inordinate amt of time at
the high hole in the (now completely dead) live
Oak gran. Gee, not a nest is it? No, the door
is gone From that hole - they're building a
new door @ 4 feet below
10ct 0845 Put door back in hole. There were some
Feather remains - is this the bird hit by the hawk?
→ very few though. SEE BACK OF PAGE →
