1994 Walter D Koering Melanerpes formicivorus CVGrande HNHR (20 May) Hole is deep but I don't think there's anything in it. 25 May 1655. Bird in the new hole! 27 May 1030. Bird in hole! Checked it: 5 eggs, fresh! ① 23.9×19.5 ② 23.7×19.5 ③ 25.0×20.6 ④ 23.4×19.0 ⑤ 23.8×19.5 29 May 1310. Noone in the hole (?), but still the 5 eggs. 30 May 1310. Finally let 82172 go (marked with green paint). The plan is to tape the hole continuously, but the batteries are screwed up and # in conjunction with today's thunderstorms (!), we only got intermittent watches on the nest. It did, however, have 5 eggs when I released him, and Katy confirmed this morning that they were incubating. 31 May Katy watched & did see a bird roost in the nest last night. Today, though, things have been unclear. As of noon or so, based on Jeremy's watch from 0600~0900 and tapes subsequently, there has been but 1 visit to the nest so far - by 82172! He stayed inside for ~10 minutes but did nothing else! But why is noone else coming to the nest? It would really be a bummer to have them abandon it. I checked at the 1445 tape turnover and all 5 eggs were still there. 82172 tossed all the eggs this afternoon! Katy had the 1st; the others were between 1754-1806. See back for details. 28 June 1615. 3 kits in the new hole across the road & up the hill found by Katy this morning: ① Y (42.1, 20) ② DB (38.8, 19) ③ LG (35.1, 17) ~9-10 do. ELED > 7 June
