2001 2002 2003 Walter Poenry Melanerpes formicivorus Lower Long Field HATCR 10 May 1430. After sitting here for 45 min and not really seeing anything I walked around the sycamores and bingo! A bird in a hole! 11 May 1600. Opened the hole: 7 eggs, incubated. Measured one: 25.1 x 19.8. Hole tagged #1316, 16 May 1500. 4 babies, 1-2 do, + 3 unhatched (but developed) eggs. Band ~ 4 June.
