Melanerpes formicivorus
Bianca
(28 April) 1100. Birds are eating oak flowers now.
1105. Still noone in holes.
1115. Leaving.
1 May
1815. ♂140, several others over in the knoll area above the Valley
Oak storage tree. Nobody in a hole, however, that I can find!
2 May
1710. Ms. Bianca sat for me near the nest area for a spell, but
noone else was conspicuous and nobody was in a hole.
1715. ♀251 (RRR) showed up in same place; then (both flew)
off, Ms. Bianca going over to the area low in the territory
with the large live oaks. Maybe there?
4 May
1710. ♀Ms.B. seen again. All holes checked.
Birds are pretty well spread throughout the area. At this
time mostly just sitting, except for my disturbance.
1730. Several birds responded to the kent-get heralding
an intruder near the nest area (an unring ♀), including
♀141 (seen well) and ♂142 (♂Red/Wn - still conceivably confused
with ♂214 (Or/Wn) but I don't think so in this case).
1750. ♂Or/Wn up in upper end of territory. This bird
clearly had a wing streamer on the left wing at one
time - I assume that he is ♂214.
6 May
1720. Several (~4+) birds near nest/storage tree, including
Ms. Bianca #140 and ♀RRR#251. They flew up to the knoll.
1745. Ms. Bianca and ♂ub#365 back in storage area; they
seem to be flying off across the canyon or at least on
the other side of the knoll.
7 May
930. Watching. One bird flushed from old storage tree and ♀Ms. Bianca
over in a main storage area.
