④♂561 + ♂562 moved to Hay Blom ~7 June 1982
Molly last saw these ♂ at 1800 22 May, and they were
missing on 30 May. However, the ♂173 at ItB probably
didn't die until 4 or 5 June. Also Leslie saw ♂562
look into the Hay Blom nest on 30 May after the
nest had apparently failed, but before ♂173's death
(See Leslie's 30 May nest watch)
15 July Walking up Haystack Obs I find several birds
flycatching from the Utility poles near the 2 VO's
along the fence approaching the top of the hill. They are
all 1800 birds and I even find all 3 Juveniles! J785
m / DBLue-Yellow
J786 6cm / DGrn-8Pkt(m)
and J787
yellow-wnt/Red-white. What's more, I ever saw J785
peck hard at J786 twice while the two were perched
on a utility pole. 0645, another J785 pecks J786
+ plus a good hit that 786 is dominant over 787.
On the utility pole, 786 lunged at 787, and 787
turned away + chattered. No contact though. ♂347
+ ♂476 also seen
