1997 Walter D. Koenig Mulanerpes formicivorus Plague (13 May) night. So I went up and sure enough, the entire bottom of the cavity was soaking wet. Not a likely nest; in fact, it's amazing if someone's actually roosting here. 15 May 1200. Checked a hole in the 2° tree pointed out by Monica where the birds had been—in fact, a ♂ was in the hole when we came to look. I opened it, and there is nothing in it yet. 1930. Watching: 1940. ♂22 alone in 2° tree. 2000. ♀157 and ♂361 arrived simultaneously next to ♂22; I gave impression of briefly trying to mount ♂22, but a quick shift of positions, possibly by ♂361, brought her off; then ♂22 flew off, ♀157 sat up a ways while ♂361 stayed in the same area. 2010. ♀157, ♂361 flew up canyon, ♂22 found next to pump- house. Going up, 2 birds were seen sitting up the canyon, then flushed back down. Returning, I then found all 3 together on a limb in the 2° tree. After several minutes, ♀157 went to the telephone pole and roosted; neither ♂ joined her, but I was unable to tell for sure where either of them did go. I think both roosted somewhere or another in the 2° tree. 19 May Monica's last day; notes are all mine from here on. I watched at dusk; at one point seeing ♂22 and ♀157 together atop Plague; the ♂ mounted the ♀ for several seconds, the ♂ however only had a very brief time on the ♀ before ♂361 flew in and all sat reserved. In the end, ♂22 roosted in the telephone pole; I have no idea where the other 2 went.
