2002 2003 2004 Walden Koenig Melanerpes formicarius Buckeye HNHR 8 May 1510. Bird in a hole in the (gulp) granary. We're talking the 40' ladder, I fear. 13 May 1035. Bird in same hole. Assuming eggs were fairly new on the 8th, this puts hatching on or about 18 May and banding ~9 June. 23 May 900. Opened the new hole in the granary: 4 babies, ~10 do. Band ~2 June! lots of stores here. 29 May 930. Banded the 4 kids (#3699-3702). All in good shape 23 August Still stores - a fair number, in fact. 2003 25 April 1200. Birds & stores here. None in a hole, but birds hanging out by the granary. 26 May 1345. Lots of stores, but still no sign of a nest. 28 Sept 820. Still stores here, presumably from last year. 2004 5 March 1440.
