Plague
Hastings Reservation
14 January
1515. Went outside long enough to get all 4 birds here
sitting atop the Plague tree together. The babies, by the
way, have molted: 521 is a ♂ and 522 is a ♀.
3 February
1215. Both babies (♂521, ♀522) up hawking from the top of
Plague.
4 February
950. Watching now with our 2nd yr captive ♀ up in a cage
in the 2° tree. She has yet to make a sound since I took her
out of Red House and is quiet and calm now. The residents are up

it, apparently ignoring her. Is now atop 2° tree eating the acorn.
1055. ♂521 is on a line ~8 ft away, obviously interested.
Meanwhile one of the ♀♀ is hawking atop the tree.
1100. Both ♀♀ in the tree now. ♂521 still the only bird near
the captive. ♂521 preening at the moment.
1104. ♂521 finally flew off. Several birds war here now but
none in the vicinity of the cage.
1112. The other baby (♀522) here also. Both babies are busy
moving stores around in the granaries.
1150. Quitting. Still no clear interest in the captive, though
birds are in the area still. ♂521 came the closest to her.
12 February
1600. Counted stores: Plague tree: 1397? Total: 1867
Other: 470(est.- includes an est. 300 in the
roost
holes in the telephone pole, which are still full to the brim).
15 February
1705. Some calls here in the Plague tree were directed at a
crow. The bird who actually buzzed the bird and was
