1983 R.L. Mumme Melanerpes formicivorus Chongo 6 Jan Watching from Buckeye, 1230-1300, I see the ♂NB and ♀ dark left eye in the granary, but nobody else. Juv 801, not seen since the day he fledged, must certainly be gone. The 2 birds flew across Mudro-e Canyon toward Buckeye at 1300. 17 Jan ** GROUP UPDATE ** 1982 J801 disappeared 20 July ± 1 Month.

After flushing a bird out of the 82 nest hole in the granary, at 1630 I climb up and find 7 eggs (!) including 1 raut (!!), leading me to suspect strongly that there is more than 1 dark left eye here. Eggs quite fresh ~1day @ De-ise reports SHILL 9Q753+755 here. 22 May Nest check, 1515.

This clutch hatched late, because incubation was apparently delayed for a day or two here (see Walter's notes June Walter reports failure, dead nestling in hole, absence of acorns,
