1976 Walter D. Koenig Melanerpes formicivorus Plaque 8 April 1025. Watching. Several birds here. 1028. 2 88 atop Plaque with Starling. (1) 8 LBlue/yellow #157. 2nd flaw over to Sycamore by creek where she was greeted. 1033. 88W chased a bird who was in the lone tree above the labs; continued after it when it flew into main area. 1036. Unbanded 8 atop Plaque for a minute; looked furtive up until chasse being displaced by 8245 and (3) 8387. More birds around than there should be. Some Garricle calling, but not entirely clear who. 1041. All 3 group birds in sycamore at creek. An unknown bird still in upper tree toward MacRoberts. (a 8) 1045. 2 88 still in view. 1050. 8 in upper tree is 8 LGRW#162 from MacRoberts. 1630. Saw 8162 again in '75 nest area; then flew to sycamore, where one of the 8 landed above him. After balancing for a minute and reaching up and pulling off a couple of new sycamore leaves, which she dropped (displacement? or was she trying to hit him?), she finally displaced him from the tree. All 3 group birds were seen in Plaque a few minutes later; several Starlings are still making trouble here. 11 April 730. More intruders here. I saw 3 birds, including the 2 88, up in the Blue Oak next to the Hastings Cabin, while a 4th bird, a 8, was beant cutting by the Pump. A mounting was seen among the Plaque birds, apparently the juv 8 on the ad.8? (with the 8 about a foot away). A few minutes later the intruder flew toward the labs, and was vigorously chased. Later another mounting was seen, possibly with copulation, and possibly between a 8 and 8. Activity was at a high level [illegible] All 3 birds w in 1/2m of each other The mounting of the 8 provoked no perceptible reaction from the 8 whatsoever, who was facing the other direction.
