Llworf 1964 3 Aimophila hemeralis July 15 Canor de Lobos, Pni. E. Guanacaste, Morlos, Mexico 0630 - found 2 birds foraging in shrubs on mesquite-dominated hillside. No trees in area + tallest shrubs are 10+ feet. More like habitat of A. ruficauda of which there are at least two pairs nearby - one to N + one to S, along hillside. Pair foraging in various species of shrub - do not seem to skip any a pass them over. Mostly foraging in interior of shrubs about 2/3 way up. One dropped to ground, picked up dead leg + flew to rock 3 feet away. Pat leg down + pecked something off. Then flew to next mesquite. 0648 - one flew to 'O' tree at edge of cornfield. Let other birds just inside canopy. Picked up larva + short bird with larva in beak. Not sure if letting larva against branch or no. Swallowed + bill-wiped. Hopped to next higher branch - (1/2" dia, big) + bill-wiped. Then sat chipping softly + preening. Not sure when other find it. Tree leaves are nearly all full of holes from larvae. 0656 - bird drops down toward ground + then works back up into tree. While goes out to where branch < 1/4" dia - usually is on the bare portion, branches utilized are horizontal or nearly so. Worked from outside W of tree to inside + to outside W. Then to center (all w 6-7' up) then dropped down 2-3 feet and worked toward outside S - chipping softly. 0700 - by this time reunion chatter is reduced in frequency from 0600. Only infrequently does isolated pair chatter. Earlier it sounded as if chatter by one pair stimulated other pairs.
