Skutch (1954) also commented on this use of the bill and noted that the bird feeds on small invertebrates and at times eats decaying leaves. Its voice is thin and v/eak. In Ecuador, I noted a song as zeep, which-a-whee, with the tone dropping on the a and rising on the ichee. Skutch (1954) notes that the song is given from, or close to, the ground and de- scribes the male's song as being squealy, high-pitched, tuneless, and rapid; the fe- male's song is similar but even weaker. I noted two calls in Ecuador, a high, metallic, zeep and a soft throaty chuck. Skutch (1954) described the call as similar to that given by a Cardinal { cardinalis). Slud (1964:383) described the voice as an insect-like trill or as the "tinkling of a fine silver chain"; he also noted a cherrr which must be what I described as chuck. Breeding in Costa Rica is from February to September (Skutch, 1954), in northern i Venezuela it is from May to July (Schiifer i and Phelps, 1954). There is no information from farther south. Skutch (1954) noted that the species builds a bulky nest in dense tangles from one to six meters above the ground; two white or very pale blue eggs are laid and incubated only by the female. MorpJiological variation.—As has been discussed above, morphological variation is extensive within A. The pectoral band appears in ])\ perijanus, phaeo- pletirus, phijiias. , poliophrys, tor- quatus, and fimbriatus (faint) and is absent.
