Song variation in the brown creeper

[This is a resume of a paper read at the Ecological Society Conference, 1982.]

First paragraph:
A study of song variation in male Brown Creepers (Finschia novaeseelandiae) and its relationship to population structure and social behaviour was undertaken from 1979 to 1982. The study was conducted near Kaikoura in four remnants of lowland forest in which Leptospermum ericoides was the dominant tree species.
