29 March Start watch 0950. Nobody in granary, but one bird seen at far Tortuga. Accipiter cooperi cruises over at 1000. 1008, ♂307 (orange R), flycatches from Valley Oak in the Far Tortuga area. ♀ 1040, everybody here ♂511 white/yellow/metal,
♂461 m/blue-white, ♀515 Dbrn/yel, all flycatching like crazy. End 1050. As I leave, ♀515 goes into a huge frenzy of hawking, storing all the insects she gets in a dead stub on the S side of the granary. The holes she stores in are smaller than typical granary holes
Going to check nest holes.
6 April Start watch 1530. Nobody here. 1550, ♀515 Dbrn-yellow eating stored acorn in suppl. granary (F). 1555, ♂307 arrives, wakas with ♀515. He also eats stored acorn. No sign of ♂461,
so no "packing" yet. End 1630.
10 April Start watch 1100. Nobody in granary as I arrive. Hole check produced nothing. 1125, ♀515 in tape hole tree, flycatches (F)
1210. Pretty dull here, ♂307 here too, but birds are very blasé. No sign of nesting (although ♀515 did peer in the granary hole once). No sign of ♂461, ♂511. End 1215.
15 April Start 0845 ♂307 + ♀515 in granary as I arrive, plus a 3rd bird at the top of the hill. 0855 ♂NB in granary, chased hard by ♀515, less by ♂307. ♀515 gleans from leaves (F). All these new leaves, I've seen a lot of that.
0915. I'm wondering if ♂461 + ♂511 aren't trying to disperse somewhere. I haven't seen them around, although Nancy has seen 3+4 birds at roosting. 0925, I take that back, ♂461 cruises across territory, ♂461 Dblue-white/Lblue-white.
