1983 R.C.Mumme M.fornicivorus Finch 22June Watching here, 1230-1300: I'm convinced Finch is not interested in nesting. No evidence of guarding of 9541, or food carrying. 66, 9541, 613, 816 the tinky birds seen- 29June ** GROUP UPDATE ** ① 501 disappeared 15 Feb 1983 ± 1 month. Last see- 10 Jan, gone for sure 21 March ② 282 + 540 moved + founded Mac Flat 24 Dec 1982 ± 2 weeks Last seen by Alan at Finch 9 Dec 82. Definitely gone from Finch by 10 Jan 9July 1500 Strange happenings here. On the way up to Road 1 am, distracted by calling juveniles, I find that, like Plaque, Finch seems to be in the process of adopting juveniles. One banded juvenile grandchild of Finch from MacFlat, so that is similar to the stay at Plague. However there are at least two (perhaps 3 or more) unbanded juveniles as well. At first I was afraid that I had missed a nest, and that JuvUB's were Finch offspring. However, they were being chased + pecked fairly vigorously by Finch adults (similar to the way the Plague adults treated the Pipeline juvenile) and never saw any adults feed the juveniles. I also got the impression that the MacFlat baby was being treated more equitably than the unbandeds, further suggesting that the unbanded were not Finch offspring. Anyway, this situation bears further watching. 63, 66b, 541, 542, 543, 613, 616 all seen well,
