1991 1992 Walter D Koenig Melanerpes formicivorus Upper PHF HNEUR (30 May) The bird who was in the hole when I got there had stayed in, even though I'd climbed up to the hole to scare him out. I don't think I scared anybody away otherwise, and no one else even came to the hole (even though I could hear them elsewhere in the tree and eventually roosting nearby). 2 June 1515. Hole completely empty! Note my roost watch above; if indeed I keep a bird from roosting that may have been enough to kill the nest. Predation can't be ruled out, however. There are stores remaining here, by the way. 14 June 900. No sign of anyone up here. So what's going on? Why aren't they renesting? 15 July 1525. Still stores here. No sign of birds, though (except for MPHF birds hanging out here). 1992 4 April 1340. There are just a few intact acorns remaining here in the main gravany. 10 April 1600. Set out a feeder in the nest tree; this is a supplemented group this year. 18 April 515. At long last, an ambush in a new hole in the nest tree netted all 4 birds, including the ♀ NOBA. End of an era. We bled everyone and then Mark took 2 of the 38 in to be lapped. 9 May 1000. Bird flushed from the blue oak with holes over in The little canyon N of main PHF area; a nest?
