20 tree: 167
Misc: 97
Total 3014
This group is doing fine, but even here the granary isn't especially full. Also, they lost a limb last month of unknown size (to me),
but apparently large enough to be of note (300 holes?)
3 March *Group Update*

900. Several birds fighting here; not a real power struggle
but something is definitely going on.
90s. ? or /R-w(m) #1729 drumming (8 helper) over in the locust by Jim's
Garage.

1400. Lots of chasing here (and there has been for the past
hour at least). Also, I mended the "traditional"
rest hole. 2? → 8973
①♀ M/Red ? ②♂ M (only band) → ③♀ Reb/Wk-LB #973
④ LG/DB (good look) is ♀ DB /M #973.
1430. There may be only 2 birds (8973 & 8♂LG/DB ) in the
central area, always following each other. There are at
least 2 other birds gamracking off in the periphery somewhere.
1450. Too hard to ID the peripheral birds. Leaving. The
2 birds, at least, look pretty tight.
The♂ would appear to be 81757, a Chongo baby from 1989
not seen after banding!!!
