Abstract
The study monitored the Black Phoebe along the Cali River to determine suitability as a bioindicator of water quality in urban areas. Recorded type of perch, forage substrates, and forage frequency, estimated size of territory defended by each mated pair, and characterized preferred habitat. Arthropod samples were collected to assess food availability. The results suggest that the Black Phoebe should not be used as an indicator of the biotic integrity of rivers in urban settings. Its activities are not restricted by the quality of its environment, as it has a flexible diet and responds well to a variety of offerings.
