1981 R.L. Murme Acorn woodpecker School Hill Hastings Reservation 29 April Nestcheck at 1130. 5 eggs still OK, plus the plaster egg introduced by Walter. Not thrown out in over 48 hours. I then introduce one of the dice Walter introduced this egg, afternoon (16 mm) (______). Also measured eggs ① 26.0 x 20.3 did not hatch (or develop) ② 25.8 x 20.4 hatched (#) has nothing to do ③ 25.4 x 20.1 hatched with laying sequence ④ 26.7 x 20.1 hatched ⑤ 25.0 x 19.6 did not hatch (or develop) 30 April A strikeout at roosting. A bird came very late (1925) and I couldn't see anything. 1 May Nest check 1230. The die was still in. Not thrown out within 48 hours. Roosting, a ♀ looking out as I arrive at 1900. → She leaves at 1920, But nobody else comes to hole(!) Strange. Could have been a second bird in, I suppose. 8 May Nestcheck 1340. 3 babies, 2 eggs (neither of which appeared to have developed. Did not bad babies, will have to do that in a couple of days. Eggs #1 + #5 did not hatch. Young seemed fine + healthy, All 3 should Fledge (I hope). 12 May Roosting, and confusion. I said hello when I arrived, nobody looked out, about 1920 either ♀260 flies to the hole, enters, Then a sure ♀ leaves, while ♂86 comes to the hole, then flies off with the ♀ to roost in the 80.2 next hole. Later, I get a shock by seeing a bird looking out, I don't think I missed anyone going in, so I'd say ♂402 roosted
