Yellow-knobbed Curassow

The Yellow-knobbed Curassow is a large species of bird found in forest and woodland in Colombia and Venezuela. It feeds mainly on the ground, but flies up into trees if threatened. Its most striking features are its crest, made of feathers that curl forward, and the fleshy yellow knob at the base of its bill. Females lack this fleshy yellow knob, but otherwise resemble the male in the plumage, being overall black with a white crissum. The adult is 84-92.5 cm It eats fruits, leaves, seeds, and small animals. Unlike most other gamebirds, curassows nest off the ground, with both sexes helping in the construction. The female lays just 2 eggs - a tiny clutch compared to those of many ground-nesting gamebirds.

The Yellow-knobbed Curassow is classified as Near Threatened (NT), is close to qualifying for or is likely to qualify for a threatened category in the near future.

In addition the male Yellow-knobbed Curassow has two pendant wattles on the man- dible. Although the adaptive significance of this ornamentation is not known, sexually selected functions have been proposed for "fleshy" or- naments in this species (Delacour and Amadon 1973, Buchholz 1989) and have been described in related species (Brodsky 1988, Zuk et al. 1990). My goal was to determine which sexual selec- tion model might account for the evolution of curassow knobs and wattles. More

daubentoni)! Yellow-knobbed Curassow Day was decreed by Brad Walker, one of the current techs working on the Forpus project that I participated in last fall. Reasons for this decree are unimportant - the magnificence and wonder of these birds overwhelms all. During my time in Venezuela, I repeatedly tried to capture that magnificence on camera but was left crying in abject failure. More

of the Great, Blue-billed, and Yellow-knobbed Curassows, which were isolated from each other by the uplift of the northern Cordillera Occidental, and the Serrania del Perija, respectively; it is fairly certain that these lineages were well distinct by the end of the Miocene. (Pereira & Baker 2004) The evolution of the 4 southern species was somewhat more complex. In the Messinian, about 6-5.5 mya, the ancestors of the Wattled Curassow became isolated in the western Amazonas basin. More
