1050. Watching. ①♀ Br-Yel/Blk #519 in Gate sycamore. No undue activity here.
1052. Over by the WGate sycamore, however, is ②♀ unbanded. With a Live Oak acorn she pilfered from the WGate tree.
1100. There's at least 1 ♀ and ③♂ unbanded hanging out in the Live Oak nest tree. Some of the Live Oaks back here are still loaded with acorns, by the way.
1118. ♂ unb. in Gate tree.
1120. Leaving. Well, whatever's going on here, it's clear that my previous simplistic interpretation of events here is just not going to do the trick. Either there's been considerable additional turnover since the ambush on 1 Jan., or a 2nd possibility - at least in part - is that the birds here at Gate are in fact separate from ⑤♀8, the unbanded ♀, and possibly the same old unbanded ♂, who may still be as before only back restricted to WGate. In other words, this territory may have split once again. This interpretation doesn't explain everything, but it is consistent with the general pattern of observations back here; e.g. that ⑤♀19 is never in WGate and ⑤♀8 is never in Gate, plus the persistence of an unb ♀ at WGate, and so on. If this interpretation holds up, everything will be definitely in for more rearranging soon.
1135. I'm almost convinced - in the trees beyond WGate Syc. by Hallisey's were 3 birds: ①♂8, ②♀ub, and a 3rd bird. This could very well still be the intact WGate group.

Inasmuch as the above scenario makes much better sense at this point than any alternative I can think of I'm making the following changes in the records:
