1981 R.L. Mumme Melanerpes formicivorus Road 1 (21 April) 0812 9393 enters. Leaves 0821 0828 9393 enters. Leaves 0832, 98'294 & 578 enter. Both ♂♂ leave by 0840. 0845, confusion. ♂496. ♀269, ♂486 in hole. ♂3 ♂486 no longer following ♀269. 0854, ♀383 enters; 0905, ♀269 replaces ♀383, 0919 ♀269 leaves. 0920, Going to check nest. [illegible] 0945, well, too bad. Only one egg laid, marked #2 and measured 25.0 x 21.0 mm. Don't know who, but seems too wide for ♀269. On the other hand, it seems like ♀269 was more likely to lay, since ♀383 has already crated out 5 eggs before today. Will have to check walters records of ♀383 egg dimensions. 22 April Watched roosting, without seeing much. ♀269 was escorted tonight in the grassy by a ♂ (presumed 486) with no others around. No outings seen. ♀269 roosted in the upper of the 2 holes in the grassy. 25 April Roosting at the nest. A ♂ was in the hole (I thought ♂3 ♂486) when a 2nd bird with M band lower left (♂486 ♀269?) came to the hole, entered. Chattering then one bird flew out. In short, I don't know who roosted in the nest. 26 April Roosting, this time ♂486 roosted for sure. I picked up his lower left Metal Band when he flew into the grassy, then followed him all the way to the nest hole, replacing a ♀. 28 April Roosting, ♀269 (I think) was in the hole, but she was relieved by a bird with a lower left metal band. Thus ♂486 roosted in the nest 4 May Struck out at roosting. A very late exchange. Couldn't see anything. 5 May Checked the nest at 1530 Hatching! 3 Babies, 5 eggs
