Behavior

Behavior

Golden-eared Tanagers forage by "[hopping] along bare branches, peering down from side to side and pausing to probe clumps of epiphytic mosses" (Parker and Parker 1982). When foraging for arthropods, they are considered "thick branch, moss foragers," using moss and partially-moss covered branches 95% of the time, when compared to other Tangara species in the same study (Naoki 2003). When foraging for arthropods, the Golden-eared Tanager use perches of much greater diameter than when foraging on fruit. For example, 57% of arthropod foraging observations were on perches 20-69 mm (Naoki 2003). A variety of foraging methods are used such as pull/bite (42%), reach-down (25%), hang-down (14%), and probe (14%) (Naoki 2003). It typically forages for arthropods on the uppersides of branches, but will also occasionally use a diagonal-lean method to obtain prey (Isler and Isler 1999, Schulenberg et al. 2007). Attack maneuvers used in fruit foraging include: glean (61%), reach-down (14%), and hang-down (9%). When foraaing for arthropods, they are considered "thick branch, moss foragers," using moss and partially-moss covered branches 95% of the time, when compared to other Tangara species in the same study (Naoki 2003).

Territoriality

No information has been documented, but the behavior described above for captive individuals indicate this species may be territorial in nature.

Sexual Behavior

Little information. In captivity, they have been seen raising the ear coverts while singing a hissing, piping song (Ingels 1974).

Social and interspecific behavior

Usually observed alone, in pairs, or in a group of three-four individuals (Isler and Isler 1999). Also one-two are observed in large mixed flocks of tanagers and honeycreepers (Parker and Parker 1981). In Bolivia, flock associates include Golden Tanager (Tangara arthus), Saffron-crowned Tanager (T. xanthocephala), Blue-browed Tanager (T. chrysotis), Blue-necked Tanager (T. cyanicollis), Spotted Tanager (T. punctata), Beryl-spangled Tanager (Tangara nigroviridis), Orange-eared Tanager (Chlorochrysa calliparaea), Deep-blue Flowerpiercer (Diglossa glauca), and Orange-bellied Euphonia (Euphonia xanthogaster) (Remsen 1984). Joins feeding aggregations at fruiting trees (Isler and Isler 1999).
