Abstract

On 1 August 2000, a house wren (Troglodytes aedon) was observed exhibiting intra-specific helping behavior. An unbanded individual was observed carrying a spider into and separately carrying a fecal sac from a nest box occupied by 2 color-banded adults. The feeding individual appeared to be a hatch-year bird using the aging criteria of tail-length, breast coloration, and rictus characteristics. There were no additional observations of feeding by any unbanded individuals during the 1-h sample or in 3 hourly samples over the next 3 days. It is not known if there was any genetic relationship between the house wrens occupying the nest box and the unbanded juvenile helper.
