BREEDING OF THE BRUBRU SHRIKE

Summary Tarboton, Warwick, 1984. Breeding of the Brubru Shrike. Ostrich 55:97-101. Brubru Shrikes occurred in pairs which occupied permanent territories 33–42 ha in size in the broadleaved woodlands at Nylsvley, Transvaal. They nested in early summer; both sexes shared equally in nest-building, incubation and brooding and feeding the young; incubation lasted 19 days (1) and the nestling period was 21–22 days (1). Vocalizations, including duet-tine, are described, and the species' phylogeny and its behaviour of deserting early nests and calling while incubating are discussed.
