1981 Walker D. Koenig Melanerpes formicivorus Lambert (30 April) on 22 October 1980, but presumably (?) around until the time of the Revolution to replace her on 13 April. But, to be a little more realistic, I'll give her a 2 month leeway: Disappeared about 13 March ± 1 month. ♂ 581. Last seen 1 December 1980, gone by 13 April → Disappeared about 7 Feb. ± 2 months Add: ♀ unband. Presumably moved here during the Revolution on ~13 April. In fact, this group continues to present one of the biggest problems in the whole study area. Stay tuned for more speculation as time goes on... 2 May 630. Watching. Something up here: 5 birds in the '80 nest tree when I came up! 640. A fairly good revolution! Looks like it primarily involves 88 this time; there are numerous ub 88 have plus at least 2 banded ones; also ≥ 1 ub ♀ - presumably the new resident. About 10 birds altogether, I'd say. 700. Looks good for 008 BP/M #583. He seems fairly well in charge, along with at least 1 other (banded?) ♀. An unbanded ♀ seems to have that position with no problem. Things are much quieter already (as the fog rolls in). 730. I'm pretty sure that 008 CB-BLK/M #582 is here also, but he's definitely maintaining a low profile compared to 8583. There are only a couple of intruders left now. 740. Even though it's the ♀(s) who are doing the chasing, it's the ♀ who still sits around drumming and Carrickin'!
