Melanerpes formicivorus
Plague
(20 July)
1410. The above 2 seem to be the only major banded birds around;
most others are unringed. The 2 banded birds also seem to be
hanging around together more than randomly. Right now
only 5-6 birds are active outside the sap area; chasing is
not great nor is activity extraordinarily high.
1415. Some chasing again.
1418. $157 remains notable in that she seems to rush off and
wakes greet any bird (who is almost always a ♀) that lands in
the 20 tree, where she almost exclusively is staying.
1420. I caught a bird: ♂ DB-LP/DB
812-35735/LP#193 from School Hill
1445. $193 let loose. Generally high level of activity present still.
1455. Just caught another bird. An unringed ♀, now #313.
1530. Put a 2nd net up. Caught an unringed ♀, #314.
1630. Caught a 2nd unringed ♂, #315.
1715. All birds released. Things are quite quiet
outside now.
1830. Watching irregularly, very few birds had been around
during the last hour. Suddenly 4 appeared and after some
brief commotion and fighting flew to the sap tree.
1848. $157 in Locusts by the bunkhouse; others still in Live Oak sap tree
1850. 2 birds in 20 tree; others by bunkhouse.
1900. Birds are engaged in heavy sapsucking over there; there
is not a whole lot of activity and they are virtually invisible.
I'm off (nets will remain for now).
No more birds had been caught by the time I took the nets down
at 2030. At dusk, I only saw/heard 2 birds; the others had all
apparently gone home.
