Physical charateristics
Pearly-breasted cuckoos are medium birds (26 to 30 cm long; 55 to 65 g) with long tails. This species is sympatric with C. americanus. They have uniform Earth-brown plumage on their head and back, and silky white underparts. Their tails are long with two rows of four to six large white circles on the underside. The bill of is short to medium in length and curved downward and orange witha black tip. Pearly-breasted cuckoos have zygodactylous feet, meaning that of the four toes, the middle two point forward and the outer two point backward.

Range
South America : North, Northeast, East
Habitat
Humid forest, edge, thickets, riparian, woodland.
Reproduction
No data, clutch probably 2 eggs
Feeding habits
Pearly-breasted cuckoos primarily eat large insects including caterpillars, katydids, cicadas, grasshoppers and crickets. They also occasionally eat bird eggs, snails, small vertebrates such as frogs and lizards and some fruits and seeds. Parents feed their chicks regurgitated insects.
Conservation
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Migration
An austral migrant. Known to be present on breeding grounds during the austral summer, and in the Guianas and Venezuela during the austral winter. However, limits of breeding and non-breeding distributions have not been ascertained, patterns of movement are unclear, and paucity of records in North of range means that firm conclusions can not yet be made.
