neortizgia June 6 Found 3 or 4 O.gularis together at edge of stand of this 'dead' oak & thorn trees. As I watched two birds moved off & seemed to be paired as they foraged along branches of a sparsely-leaved oak, pecking at lichens & exploring in the few 'penchable' epiphytes. Most of foraging done on bark, howeveres, but this never failed to investigate and epiphyte when they encountered one. I saw one bird approach the other preening groom the neck of it while I stood watch- less. These birds were silent but before seeing them I heard several short, 'raty' chir-notes. Collected one of these. Later in day I collected another adult in thorn-scrub near camp. These species are not common. I saw only one nest - an old dry one - when I touched it with my shotgun a small mouse jumped out, fell to ground (7 feet) & ran off. The nest was placed ± 7 feet up in a small dead tree (not thorny) [illegible]. I also collected Melozone (common in dense thorn vegetation lining bottom of gullies) and Thryomane, kiwieki's other bird (see catalog). The Thryomanes are scarce but seem to be in same habitat as gularis. Once I saw a Thryomane dive at a gularis which had just flown into the same bush with the male won. The attack was more or less ignored by the gularis. Foraging is at mid-levels in vegetation - usually in trees & fair size bush but they also seek small, low- thorn vegetation. These birds seemed frequented quite
