1980 Walter D. Koenig 3 Melanerpes fomiticivorus Buckeye (15 April) ended up roosting after a lot of rigamarole; noone roosted in the granary as far as I could tell, while apparently everyone else roosted in the '79 nest hole. 16 April 930. Today I was going to set up an ambush at the '79 nest hole only to discover that they already have 4 eggs - fresh and not being incubated yet! Thus, my immediate plans are changed here, although I may still ambush at the other hole(s) tomorrow in order to see who's not roosting in the nest. Also, I now know some interesting things about roosting (particularly by the 1st yr 8) while the eggs were (are?) being laid. 1900. Watched roosting at the nest hole tonight. I was unable to be sure about who was who, however 2 birds definitely roosted in the nest. The first had rather light bands on his left leg and thus I guessed he was 8234. The 2nd appeared to give a brief glint of aluminum as he zipped in, and thus I think was 8252. Since this is not what was going on here last spring, however, the most prudent route may be to leave this indefinite until a better watch can be made. 17 April 1700. Noone in the hole when I came to check it: 5 eggs. 19 April 1600. Noone in the hole when I went up to check it, but this time it had 6 eggs! Sandy stayed on to see if they are incubating yet or not. 25 April 1530. Despite the continued roosting of a bird in the nest hole at night (I saw someone here on the evening of the 23rd and Ron saw 8234 roost here last night) several nestwatchers, by Sandy
