1985 Weller D. Koenig Melanerpes formicivorus Blountwo HNHR 4 April Well! I came here this afternoon with Wes Weathers & Missy and set up some nets, then tried the Power Struggle tape with a mount (bad one!). They were there immediately, all 5 of them: 8966, 8967 from Blomone and 3♀♀ - 2 ub and ♀960 (incorrectly listed as a ♀) from CV#2. Neat! So it would appear we have 2 brothers (known) and 3 breeding ♀♀ here, the latter from CV#2. The tape worked well - at least to bring them in - and Wes gave me some ideas that may improve things more. We eventually caught one of the ub♀♀, who is now ♀990, so there is now only 1 ub♀ here, at least. We also saw 8832 come by briefly from Blomone to check things out. I returned as dusk. All are still there as they have been for several evenings. But I don't think they're roosting together, even though they go through ~5-10min worth of pre-roost mounting beforehand. This evening 2 birds at least appeared to fly off toward Blomone to roost while 21 also headed toward Blountwo - almost as if everyone's still heading home to roost. 7 April 1530. Nets up; speaker and mount in tree. 1535. 8966 here; also [illegible] ♀960; intruders brought right away by the tape as usual. 1600. Not as much commotion as previously. Also not as many birds. Missy saw 8967 but neither 8990 nor the ub♀ have been seen for sure. from CVVerande 1600. Intruder: ♀ W/nm 941; also ♀ub apparently here
