Abstract

Wilson’s Bird-of-paradise Cicinnurus respublica is endemic to two islands of the Raja Ampat island group off the western tip of the Bird’s Head peninsula of the island of New Guinea. Due to its remote home, it is little known, and its courtship behaviour in the wild was not described until the 1990s. To attract females for mating, males create and maintain a clearing, known as a court, on the forest floor, where they display on perches. These displays are normally performed by solitary males, but in this paper we describe an instance of three adult males displaying simultaneously, with highly synchronised movements, in the presence of three female-plumaged birds. This cooperative display incorporated at least five postures, one of which has not been described to date, involving the bird ‘bowing’ to accentuate its yellow hind neck patch. Whilst cooperative displays have not been observed in the closest relatives of this species, the Magnificent and King Birds-of-paradise, they appear to occur regularly in the four species of parotias Parotia spp., albeit for much shorter periods of time.

Abstract

We present morphometric and moult data for the Sulawesi-endemic Dark-eared Myza, based on 35 individuals captured at Lore Lindu National Park, Central Sulawesi, during March–April and July 2011. Four individuals banded in March were recaptured at the study site in July, suggesting that the population is probably sedentary. Like most meliphagids, although this species is not sexually dimorphic in plumage, measurements show that males are significantly heavier and have longer wings, tail and head–bill than females. Seven of the 16 adults in March–April and five of the 19 in July were moulting their primary feathers. Assuming that primary moult follows breeding, estimated laying dates for adults in the final stages of moult suggest breeding in December and early April, the latter corroborated by the presence of brood patches on two females in late March. A brood patch on a female in July further suggests that the breeding season is protracted. All birds photographed also showed distinct buff tips to most, if not all, secondary coverts and buff fringes to median coverts, a feature that appears to have gone unnoticed in the literature.
