11 May
Purge: 3364. Last seen roosting on 15 March. Gone, along
with the others, by 19 April. Disappeared about 31 March ±1 week.
3322, 3414. Last seen on the knoll on 31 March.
Gone by 19 April → Disappeared about 10 April ±1 week.
I have no good explanation for what got these 3 birds,
but something must have. Their simultaneous
disappearances are a mystery indeed.
17 May
815. 3WN#415 flew by me as I checked the holes up on the
knoll.
18 May
1418. 3415 seen in the locust eating and restoring an acorn.
They do have stores - where's their nest?
20 May
1115. The minor revolution activity that was by Pump
this morning has now moved over here, with at least 1 bird
carricking up on the knoll, chasing, and 7-8 birds
flitting around: ①♀ M/or-WN#435 by the knoll with one
other bird; ②♀ YLW#434 here in sycamore roost tree - 2-3 others
there also (!) inc. ③♀ub ④♂Y-Da/or#297 (1500).
⑤♂&eDP#402 (S.Hill) in tel.pole. My goodness. Drumming
now up on the knoll. Lots of activity between the sycamore
and the barn. Leaving for now.
1350. Still 4-6 birds here - lots of action. 3434 seen, also 3297.
♀ub drumming on the old fallen granary on the knoll. Someone
carricking at the Pump.
1403. 3434, 3402, and ♀ub together in 75 nest tree. Now 5 (!)
birds here. 3WNW#415 in locusts in front of barn. But others not
chasing each other (?)
21 May
No activity here the 2 or 3 times I passed by!
