Re-use of a Rockwarbler Origma solitaria nest over a 13-year period

Abstract

This note describes the pattern of use of a Rockwarbler Origma solitaria nest over 13 years, from 1998 to 2010. Eggs were laid in the nest in only three breeding seasons, and young successfully fledged only once. Some nest-building activity occurred in five other seasons, but no eggs were laid. Two pairs of Rockwarblers laid in the nest in different years, and at least one other showed interest in using the nest in another year. Each new nesting attempt, whether by the same pair or a different pair, involved extensive reconstruction of the nest or addition of a new nest to the bottom of the old one. There was no instance of the nest being used twice in the one breeding season, but there were indications that renesting was occurring using a different nest-site for each attempt.
