ll Wolf 1964 Aimophila mystacalis August 16 16.5 W - 3W Matatlan, Oaxaca, Mexico Foraging done mostly on ground with some in foliage of trees. After members of pair 3 finished snatching with pair 2 to the sexes dropped from wegey tip to grass which is 12+ inches tall & completely covering areas in field not planted in wegey. grazing | Foraging - mostly done between 1ft & 8 feet above ground. Most in shrubs + low branches of trees. Do drop to ground + work to 10+ | feet in trees. Only items seen were insects - tree crickets, grasshoppers | Forage by working along one branch - usually horizontal, but did see one cling to vertical trunk before dropping to ground. | Slow & methodical except rapid movements when changing perches. | Move to new perch + tree about 6 feet away moving to next. More like a vireo than warbler. Most items taken were from or in foliage. | Several times bird put at item if it dropped to ground. Usually bird then followed & occasionally a chase ensued along ground. Forum movement was probably an Orthopteran being chased. snut-solo | 0900-10/10 - pair 6 - first noted as only two to dead twig at top of 15 foot pretty thorn-trunk tree. Gave chip notes + then short single part of direct chatter - accompanied for 1-2 sec. by slight wing flick. Then quiet until 2nd bird flew into tree & both began clipping + preening. One dropped toward ground apparently to lower layer while other remained in tree preening - prob. ? | 30-75 sec. later it too dropped toward ground. As I approached both flew up onto one horizontal branch 8+ feet up & bil - wiped. | Then began preening - One dropped (after 1+ min) toward ground & 2nd followed 10+ sec. later. Rest of time spent foraging.
