1983 R.C. Mumme Melanerpes formicivorus Plaque 14 April Checked the hole [illegible], 1415 (Walter found 5 eggs 13 April). 6 eggs. Is the clutch now complete? 15 April Checked the nest, 1630: Still 6 eggs. Probably all over here. 18 April Walter removes the 6 eggs from the nest here. 26 April Return from Berkeley today + Denise reports that while watching the Plaque nest hole today, She saw a Q fly out at 0628 (early!) carrying an egg. Unfortunately, we don't know who laid it or who threw it out. Unfortunate, but maybe we'll be lucky tomorrow. See Phillip + Denise's notes. Phillip checked the hole found it empty sometime yesterday morning. See Philip + Denise's notes for details. 27 April Good watch at Plague! Basically, both Q laid simultaneously between 0650 and 0720, 1 normal egg, one runt. I measured the eggs + I'm confident that the normal egg (27.2 x 20.3) was laid by Q494 (see past-years egg dimensions) and the long narrow runt laid by Q496 (21.2 x 14.8) Q496 always lays long, skinny eggs, and never has laid an egg wider than 20 mm. Anyway, Phillip I watched more, Q496 removed both eggs, the runt first at ~ 0850 [illegible] followed by the normal egg ~ 1020. See Phillips notes for exact details. I saw a bird fly out with the runt egg ~ 0950, whereupon it was carried to
