Abstract

Green (Chloroceryle americana), Ringed (Ceryle torquata) and Belted Kingfishers (Ceryle alcyon) were studied in the Rio Grande Valley, TX to determine interspecific features of perch sites. Microhabitat characteristics of perch sites appeared similar among the three species, but multivariate analysis indicated little overlap of physical characteristics for Green and Ringed Kingfisher perches. There was extensive overlap of Belted Kingfisher perch site features with those of the other two species during seasonal coexistence. Interspecific encounters between Belted and Ringed Kingfishers are described. Conditions facilitating competitive use of perch sites by kingfishers were associated with a water development project.
