Bush-shrikes (Malaconotidae)

Swamp Boubou (Laniarius bicolor) - HBW 14, p. 107

French: Gonolek à ventre blanc German: Sumpfwürger Spanish: Bubú Bicolor
Other common names: Gabon/Gaboon Boubou, Ngami Bush-shrike/Boubou

Taxonomy: Dryoscopus bicolor Hartlaub, 1857, Gabon.
Recent molecular-genetic analyses indicate that this species is closest to L. ferrugineus and L. sublacteus, the three composing a sister lineage to L. aethiopicus and L. turatii. Has in the past been treated as a race of L. ferrugineus, and sometimes considered to form a superspecies with latter and L. aethiopicus; but overlaps in range with L. aethiopicus around Chobe-Zambezi confuence, where the two occupy different habitats, and differs from L. ferrugineus in morphology (larger size but lighter weight, less robust bill) and in voice ..
