This study compares the habitat use by three species of couas, the Crested Coua Coua cristata, Coquerel's Coua C. coquereli and the Red-capped Coua C. rujiceps, in a dry forest at Ampijoroa, western Madagascar. The Crested Coua used higher layers (> 5 m) exclusively. Both Coquerel's and the Red-capped Coua stayed mainly on the ground, but the former used middle layers (1–5 m) for inactive behaviour (including resting, preening and basking) and whistling more frequently than did the Red-capped Coua. Both Coquerel's and the Red-capped Coua foraged almost exclusively on the ground but differed slightly in feeding technique. The Red-capped Coua took food on trails, relatively open areas in the forest, more frequently and more efficiently than Coquerel's Coua.
