1984 R.L. Mumme 3 Acorn Woodpecker Plague 27 April Turnoil at Plague, 0830. ♂521 ♂721 ♂723 all eve. ♂660 (who was looking solid at Pipeline a few days ago) here, but no immediate sign of ♂752. Also here are at least 2 ♀NB, being chased around by the ♂♂. Has the aggression against ♂752 finally forced her away? As of 24-25 April, my casual glances indicated a lot of chasing still going on. 1200 Pretty quiet now. All 4 ♂♂ seen again 4 May Plague continues to have its problems, 0800, an unbated ♀ here, being chased around most vigorously by ♂521, also a bit by ♂752. 23 May Finally settled here. 0700, 0830, I find ♂521, ♀752, ♂721 ♂723. ♂660 was here yesterday, but not this morning. No chasing of ♀752, so it looks much better for her. Also, Plague is excavating a new nest hole in a dead stub of one of the "firecliff" Valley Oaks along the water-table hill ravine. I climbed up ↑ found no eggs, and the hole still has always to go. It also looks like ♂521, plus perhaps ♂721, is guarding ♀752. Will have to keep tabs here 24-25 May Definitely not settled! A minor power struggle is progress here all afternoon. ♂660 (at Warp 5 in the morning) ♂521, ♂721, ♂723, all here but no sign of ♀752. ♀578 of Road 1 and at least 1 ♀NB here, garricking and being chased by the ♂♂. However, by 0900 on 25 May ♀752 is back looking cozy with ♂521, ♂721 ♂723 (♂660 presumably back at Warp 5). Huh!
