Territory switching behavior in a sedentary tropical passerine, the dusky antbirds Cercomacra tyrannina
Dusky Antbird (Cercomacra tyrannina) Science Article 1 abstract Demographic data from an 8-year study of a marked population showed that switching territories and mates is common in both genders of dusky antbirds (Cercomacra tyrannina), a sedentary neotropical passerine with year-round territories and pairbonds. We conducted 22 experimental removals and followed six natural disappearances to examine […]
FORAGING BEHAVIOR, ECO-MORPHOLOGY, AND SYSTEMATICS OF SOME ANTSHRIKES (FORMICARIIDae: THAMNOMANES)
Dusky-throated Antshrike (Thamnomanes ardesiacus) Science Article 1 abstract The external morphology of a bird is a reflection of two factors: phylogeny and adaptations to the environment. Traditionally birds have been classified by systematists on the basis of similarities in morphology, especially at lower taxonomic ranks. Ecologists frequently study the same morphological characters used by systematists […]
COOPERATIVE ROLES IN MIXED FLOCKS OF ANTWRENS (FORMICARIIDae)
Dot-winged Antwren (Microrhopias quixensis) Science Article 2 abstract Under certain conditions, flocking might enhance the foraging efficiencies of some or all the participating in- dividuals. For instance, individuals might capture insects flushed by other members of the flock (Swynnerton, 1915; Brosset, 1969), or flocks might exploit patches of abundant food more efficiently than solitary individuals […]
SEXUAL ROLES IN THE DOT-WINGED ANTWREN (MICRORHOPIAS QUIXENSIS), A TROPICAL FOREST PASSERINE
Dot-winged Antwren (Microrhopias quixensis) Science Article 1 abstract Dot-winged Antwrens maintain long-term pair bonds on year-long territories in tropical forests and woodland of Central and South America. Pairs partition breeding-related activities nearly equally. Like other antbirds (Formicariidae), both sexes incubate and brood. Both sexes participate equally in territorial maintenance behavior, which primarily involves active border […]
