Melanerpes formicivorus
Plaque
Hastings Reservation
(1 March)
trees behind the barn a Cooper's laugh call rang out
and an adult flew right through these trees coming
from up Matrone Canyon somewhere. He did not get one
of the wickers.
1732. Now all 3 birds are atop Plaque again, along with a
Magpie (1-2 have been up here all along). The ♂ hopped
up toward the one that remained, and temporarily
appeared to get successfully rebuffed as he swung down
to the underside of the branch just below the Magpie.
Not to let the formidable size of the bird stop him, however,
he quickly righted himself and jumped up to the Magpie,
raising his neck feathers, and in a brief skirmish
succeeded in having the Magpie fly off!
1537. The juv. ♂ (154) briefly walked up the limb to and mounted
the adult ♀ (245) atop Plaque.
After having driven off the Magpie, it seems odd to look at
where the 2 ♀ still are in Plaque and see 2 Robins above them
sitting unmolested — about where the Magpies had been.
1542. The Ad♂ just flew over to the Bluevale staging tree (up toward
the hill toward MacRoberts) and was immediately greeted (and
mounted?), no doubt by the ♂.
1545. The ♂, who is indeed unbanded, and the Ad♀ returned to Plaque
tree; the ♂ took some acorn meat and flew to the top, where he
eat it.

600. Finally ambushed, successfully getting 3 birds from the hole, but
then having all except the adult ♀ escape as I brought
the net down! She was weighed, etc. #156 is surely gone.
