Melanerpes formicivorus

HNHR
6 June
*Group Update*
3977. Last seen 28 March (MKH), gone by 3 May, when Mark saw lots of "extra" birds here (who nested by 10 May).
→DA. 15 Apr ± 2 weeks, probably forced out by the new
86 here.
Add. Lots of new ♂♂, 6 of them, it would appear. (no doubt
not all of them will stay!). All are now banded save
1 (who incubated at night).
8 June
445. Ambushed all 3 holes in the nest tree this morning:
old nest hole: nobody
New hole above prior hole: ♂1387 ♂1386 and ♂1385, now ♂1426
Note that This ♂ is (presumably) the nocturnal incubator
who I missed earlier)
New nest hole: ♂1387.
I thought more birds roosted here (there were ≥5 last
ago for sure), but this was all I ended up with. In any
case, all should now be banded here.
24 June
1600. None in any holes.
3 August
Katy saw an ♂8 (the 7th!) here on 31 July;
perhaps there's yet another up there!
I'm adding him along with the others for now.
