Hastings Reservation
(13 October) only the Ad 886!
It's probably reasonable to Purge the 2 babies not seen
since bar being banded (452, 453).
14 October
Watched roosting here tonight and didn't see anyone!
18 October
1515. Jim Griffin reported some activity up here; so here I
am, and he was right--there are 4 or so birds here actively
greeting each other ant flying around. 08 Mau/Mau #86 here;
lots of of chasing (among the 3-4 birds)
1533. Everything stopped...(!?)
The story here is that there are a total of 3 birds, 886,
♀247 (Hay-Blon) and ♂171 (Hay-Blon). The activity is
about 90% chases of 171 who is being pursued relentlessly
by 886. 247 was never chased. She was seen eating ½
an acorn, and greeted the other birds (171 at least, but
possibly both) whenever they came near her. 171 hung in
there, giving a wheezy alarm call followed by a forceful
karit (Unk?) every once in a while when left alone for
more than a second or so. No sign of any other School Hill
birds, however.
1538. 171 apparently left at 1533; now 886 sitting quietly.
1545. That's it. All dead quiet, just like that. 886 sitting
quietly in tree 2. Intruders gone. I'm leaving.
1546. Flash! Now both 247 and 176 (Hay-Blon) are here,
886 is not chasing them. Boy I'd like one or the other of those 2♀
to move in here! Go to it, kids! (What a coup!)
1550. Someone was getting chased again.
1602. That looks like about it. At least 1♀ still here.
