1993 1994 Walden D Koenig Melanerpes formicivorus CV2 HNHE 17 July 1300. Stores remaining. No sign of a 2nd nest, though 1994 12 April 1000. Plenty of stores left here. Also, we flushed a bird from a low, new hole in the traditional garrano nest tree just above the road - a good ladder hole. 1630. Peeped the hole: 2 eggs (bird in hole again also). 13 April 1130. Opened the hole: 3 eggs. Marked 1-3 and measured: ① 24.1 x 18.7 ② 23.9 x 18.9 ③ 23.7 x 19.2 14 April 830. Checked the hole prior to Jeremy's watch: still 3 eggs (checked - still marked 1-3). Pres. laid 14 April or 15 April 18 April 1640. Checked hole: 4 eggs. ④ 23.3 x 18.5 18 May 1200. Banded the babies (all 4 + 1 transplant). 8 June Bird in a hole up at CV2a - checked it at 1400 when at least one fledgling flushed. It was empty, not ready for a renest. The question is - was this a CV2A nest or just the CV2 birds hanging out in holes, as fledglings are wont to do? We'll assume the latter... 25 July 930. Came to band the kids (they eventually did have a 2nd nest in the hole I checked on 8 June) but found only 1 fairly-recently dead baby. Measurements: Culmen: 20.5 WL: 64 6th 38? Sheath: 25 Tail: 24 Sheath: 12 Tail spots: Yes Not at all clear why he died - he doesn't even look particularly emaciated. There are plenty of stores left.
