A few of the birds of Berenty are illustrated on this page. Particularly noteworthy are the giant ground couas, Coua gigas, which are common at Berenty but largely hunted out elsewhere.
Intensive research on the Madagascar paradise flycatcher, Terpsiphone mutata, has been done by Raoul Mülder's team in Bealoka (www.zoology.unimelb.edu.au) The flycatcher has two male forms, a red one and a black-and-white one. They co-exist in stable polymorphism, which is extremely rare among birds. Tracking both DNA and behavior suggests that the black-and-white males may be sexier in terms of female mate choice, but the red forms more attentive in raising chicks, such that they maintain an evolutionary stable strategy with neither gaining a long-term advantage.
