Mating System of the Dusky Antbird, a Tropical Passerine, as Assessed by DNA Fingerprinting

Abstract

We studied the genetic mating system of the Dusky Antbird (Cercomacra tyrannina) in Panama using multilocus DNA fingerprinting. We found no evidence of extra-pair fertilization (EPF) in 15 offspring of nine families. We also found no evidence of intraspecific brood parasitism (ISBP) for 13 offspring in eight families.
