C. rufinucha 12 mi. SSW Boca del Rio, 100ft., Veracruz May 18-19 Calls: ① 'unt do it - throater than humilis and also a bit slower. ② 'wa-'heet 'wa-'het ③ chu-a-queet - given by a bird carrying nesting material at some time posturing in same manner as humilis. ④ chu-do-it - variation of #1. ⑤ arr-ow pip, arr-ow pip - given by arrow with throat puffing out. che-arr che-arr chet-chet } notes - nasal in quality. In general the calls of this species are very similar to those of humilis and are immediately recognizable. They are a bit lower in pitch or throater - also a bit slower than I remember those of humilis. There is more difference between humilis and nigricaudatus than between humilis and rufinucha. General behavior seems identical with humilis - I share the impression that this form is warier than humilis or nigricaudatus, especially the former, but it may be only that the vegetation is thicker here - harder to hunt.
