1979 Walter D. Koenig Melanerpes formicivorus Arnold L Hastings Reservation (9 May) One I got a look at while he was eating catkins and was ♂ yel-DG / yel-DG #100. 17 May 930. Both ♂ x ♀ yel-Bike / yel-Bike #100 and ♀ Pub up just past Big Tree foraging on catkins. I watched them for a minute before they flew over to one of the trees along the fence line (actually part of Keep Out). 24 May After Larry reported birds looking out of the hole in the granary here the last couple times he'd been up here (20, 21 May) I finally made it up here to check. And yes, they do have a nest. They have at least 3 eggs (probably only 3 eggs), but I couldn't be positive without gauging out half my wrist to make it to the bottom of the hole. 25 May GOD. This time I sawed up the lining enough to reach the bottom, but to no avail: the nest has failed and there were no eggs or remains inside. Nearby were birds, however, including an unbanded ♀ who is probably the one who belongs here. 29 May 1045. Nobody seen here in passing. 2 June 1700. Bird flushed out of nest hole! 3 June 1050. None in the hole this time. 7 June 1030. ♀ in hole. Going up, there are 4 fresh eggs in the nest! They're trying again! 10 June 1400. Flushed a bird from the nest hole as I went up to check the nest, which still contains 4 eggs. 11 June 1610. Bird in nest hole. 12 June 940. " " " " 17 June 1730. " " " " (go to p.6)
