1981 R.L. Mumme Delanerpes formicivorus Y 15 Oct A quick stop here reveals ♂402 yellow / D Pink, along with J♂669, J♀668, and two ♀NB. Is ♂402 going to move here, too? 17 Oct A failed ambushed attempt here, in the "easy" hole in the S Hill ravine. Unfortunately, I missed the fact that the stub above the hole was directly connected to the cavity. Burner. I pulled the string at about 2000 hrs on 16 Oct, and I may have heard a bird fly out then. Oh, well. Lots of action on the knoll again, at 1600 hrs. I find lots of 1800 birds (♂S64 Red-BIX / BIX-Red, Yellow-BIX / M, and ♀695 mauve / mauve) ♂561 Yellow / Black, and ♀695 mauve / mauve Cbrn / yellow two 1500 birds (♀601 [?..?] M / wht-cbrn, ♀676 DBlue-wht/BIX-wht), 2 Buckeye birds (♂663 M / Dbrn BPix (N), ♀ (finally!) 664 Cbrn-Dbrn / M). Don't know what it was all about, but the 4 Y regulars (♀668, ♂669, a ♀NB, and a fourth bird [♀NB or ♂402?] ) were still in charge of the locusts in the lower barn. Will have to check here tomorrow. 19 Oct Once again, lots of commotion at the Y. 0800. In the lower barn locusts, secure are ♂402(! here again!), ♂669, ♀668, and 2♀NB although a 3rd ♀NB appears to be here as well, getting chased. Lots of action on the knoll, too. Lots of birds going to the yellow pass, so I try putting the "corner" pan inside one of Bill's Potter Traps (a Yellow-Pan-Trap Trap?)
