Melanerpes formicivorus
Gate
Hastings Reservation
(17 May)
1540.♂? or-wym.#258 flew to top of WG tree.
1605.♀#6 on top of WG, then flew toward ARF. Bird (♂) still in hole.
1610.♂#6 and the ♀ atop WG.
1615. The poor ⚫ is still looking out of the hole, as he has been since I got here. I still don't know whether they're incubating or feeding young, but one might guess the former.
1900. Back again. Bird in hole. Another just chased off a Starling (go Woodpeckers!) from the WG tree.
1905. 3 on top of WG: ⚫58, ♀#6, ⚫258.
1910. ⚫58 flew to hole, without food (best I could tell), went in (the other bird had left, I guess), looked out, stayed inside. Incubation it is, almost for sure I should think.
1920. ⚫58 still looking out; 2nd ⚫ below him on branch. Leaving.
1923. Hold it: several birds converged on the area: the ♀ went inside the lower hole for a short time while 2 ⚫ went inside the upper one (⚫258 +?). Perhaps things aren't as far along here as I'd been thinking.

Some birds here roosting in the willows-

1230-1250. Watched, seeing ⚫RRC#238. I think they're feeding young now, but I only had a very brief look at what seemed to be a bird bringing food, so I'm not sure. They certainly do have a nest there, in any case.
20 May
1025. Bird in hole. Watching. Birds all hawking like crazy. ⚫♀#6,
⚫♂#6.
1036. Watched changeover: ⚫, after peering out for quite sometime, finally flew out, met 1-2 others in tree. A short time later another bird flew to the hole. Surely this is still in incubation.
