1977 Walter D. Koenig Melanerpes formicivorus 25 (30 June) 2040-2105. The dusk watch was pretty full tonight- no visitors except 8RF#322 at 2058, who once again stayed the night. At least 2 of the others roosted in the nearby Valley Oak; I do want to know if 8364 is doing so. 1 July 950. Measured babies. The most developed (in fact, all but the nunt) is as follows: bill darkening still; claws dark; toes now beginning to darken as are tarsi. Egg tooth still inconspicuously present on top mandible only. All feathers now just out of sheath on body, wings, tail; crown not out of sheath yet. Babies can hang on a vertical surface but don't seem to be in to climbing yet. Remiges are just barely broken thru their sheaths - those which have are 10-1 to 4 and 20-1 to 3 only in DB-Mawr; all are barely thru sheaths in DB-LP. Extensive sections of the belly, lower back + breast are still bare. 1505. Watching nest. 1550. 816 (clearly tipped ant fed) / - 1610. 816 at lip w/ an entire ½ of a smallish (~25mm in length) shelled acorn, but won't go inside.
