1984 R.L. Mumme 2 Acorn Woodpecker Finch 10 April After the turmoil here yesterday, things are quiet when I arrive at 1400. Just had an interesting thought: 9601 and 9789, who were squabbling so violently yesterday, are sisters! Both were offspring of Gate's 626, 8627, 8519, 9601 in 1980, 9789 in 1982. 9601 ever helped feed 9789, before 9601 moved to 1500. I suspect they have never been "introduced", and they were not reared together. 1410, 8542, 9789 both here, very calm, no sign of 9601 or other intruders. 2 Acorns left! 13 April Well, changes again at Finch. I find out the following ① 9601 is back, alive and she is in control. No sign of 9789. 9601 was attacking vigorously with 8542, and chasing out intruders, one of which was 9685 (blue/red/blue) her sister, and 9789's sister from Gate. Man, what a coincidence. Also a 9NB around. Lots of vigorous chasing, a "mini power struggle" ② One of the old ones" is back, none other than 863 green-BLK/orn-BLK! He is definitely here, but seems to be keeping a lower profile than either 8542 or 9601. Did see him exchange wakus with the other two birds 19 April Here at 1300 after Philip reports a power struggle in progress 17 April, Very calm, @ but cool + windy. 20 April Here with Philip & Both, 1030, a 9NB is in control here. 8542 and a second 8 (assume 863) also seen. This is Finches 3rd 99. A fair amount of chasing earlier, but now quite calm.
