1982 N.L. Mumme 4B Melanerpes formicivorus Finch 7 June Counted stores, 0830: Valley Oaks 120 Odd branches 0 Sycamore 160 TOTAL 280 Nest is still active here. 10 June Checked the nest, 1130: Two healthy nestlings ~6 days old, an unhatched runt, and no sign of the third egg-or-baby. No obvious in breeding depression here, I'm afraid. Anyway 26 June would be a good day to band these birds. 25 June Banded the two young here, now Juvs 816 + 817. Both quite healthy. See nest record. 20 July Brief watch here, 0800-0845. Both juvies are here: J816 wht/DBlue-Green + J817 white-or/m or-wht/Orange, looking hale thrifty. ♂66, ♂282, ♂501, ♀541, ♂542 also seen. No juv dominance, but I did see ♂501 peck the daylight out of both babies. 26 July Watching for juv dominant, 0830. Wow, almost instant success! 0845 in the sycamore along the S side of the road, 50m upstream from the bridge, J816 wht/DBlue-Green gave two firm, separate pats (2 different instances). to J817 or-wht/or. Adults were present at first, but not during the second. 0950, again J816 pats J817, in sycamore, being fed by ♂66, 1000 end. Good watch! ♂63, ♂66, ♂282, ♂501, ♂540, ♀541, ♂542, ♀543, ♂613, ♀616, J816, J817 all seen well.
