1983 R.C. Mumme Melanerpes formicivorus Lower Haystack 17 Jan **GROUP UPDATE** ① J772 disappeared 9 Aug 1982 ± 2 weeks; Last seen 28 July, Missing 21 Aug. 1 April Up here to check out the post-power struggle activity (see Susan + Philip's notes). As I walk up at 0825, I find 9711 (Blue/Red) briefly in the watch tree before flying off toward Hay Blom. 8832 06m / L pink of Blom also in the watch tree, along with 9b75 Grn-wht / D6m of 1500. 0900, in complete control of the 1° + 2° granary are 9524 9587 and 3 ♂️ NBS, as reported by Philip. Only occasional intrusions into the 1° or 2° granaries, and those intruders are quickly routed. They also seem to control the utility pole and the broken top tree. 8832 + 9b75 still have the watch tree, but I doubt that will last long. 0915, Getting the impression that one of the ♂️ here is not interacting with the others very much. We will, of course, have to band them soon in order to find out. 0940 also a couple of birds Over-in the 2° area, one of which is a ♀️ N.B. 5 April **GROUP UPDATE** ① ♂️ 461 removed 25 Feb 1983 ② ♂️ 770, ♂️ 771, ♂️ 774 moved to 18CO 28 March 1983 ③ 3 unbanded ♂️ moved here 30 March 1983
