Figure 20.—Yellow-winged Vireo, Vireo Aliamarillo, Vireo carmioli. Vireo carmioli is a bird of the high tree crowns, where I have some- times watched one move slowly in typical vireo fashion and then be- come more active, almost like a warbler; the large broad head and small bill give this bird a curious appearance. Eisenmann (Condor, 1962, p. 505) reported only once seeing it as low as 13 m from the ground, but whether it normally nests that far from the ground is not yet known. On October 1, 1965, he saw 1 not 7 m up in a small roadside tree above Cerro Punta. The only nests that have been discovered are 2 found by Skutch (Publ. Nutt. Orn. Club, no. 7, 1967, p. 131) in Costa Rica; both were in trees in pastures, 3 and 8 m from the ground. The diet seems to be insects and spiders gleaned from leaves and bark and, oc- casionally, picked from a leaf while the bird hovers before it. Some- times it joins mixed species flocks of other insectivores. These vireos seem to sing during much of the year; Skutch {op. cit.) has heard it in Costa Rica from early March to November. Ridgely {in litt.) has heard it in Panama in January. In Panama, Eisenmann {op. cit.) characterizes the song as a husky "cheeyah . . cheeyou . . chipcheewee, repeated a few times, with a long pause between repeti- ; Another song phrase or call is Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original work.
