The Occurrence of Common Myna Acridotheres tristis and White-vented Myna A. javanicus in Kalimantan
Full text linkStrong sexual size dimorphism in the Dark-eared Myza Myza celebensis, a Sulawesi-endemic honeyeater, with notes on its wing markings and moult
Full text linkWe 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

Full text linkNotes on breeding behaviour, ecology, taxonomy and vocalisations of Satanic Nightjar Eurostopodus diabolicus in Central Sulawesi
Full text linkThe Satanic Nightjar Eurostopodus diabolicus, rediscovered in 1996, is a hitherto poorly known nocturnal bird endemic to Sulawesi’s hill and montane forests with only two documented nest records to date. Here, we describe two further nest records from the Anaso track in Lore Lindu National Park (LLNP), Central Sulawesi, as well as threat behaviour and vocalisations of the species. We also briefly comment on its taxonomy based on our evaluation of the holotype. Both nests were found well-concealed on the ground in forest clearings with dense ferns and moss growth and both contained single chicks. The clutch size for the species is one. The incubation period is unknown, but probably similar to other Australasian Eurostopodus nightjars. We estimate the time to fledge to be about 30–45 days. Our record of an actively vocalizing individual at 2,300m asl extends the known upper elevation limit of the species. Our documentation of diagnosable plumage and vocal differences between birds in North and Central Sulawesi suggests that the species is not monotypic. Although our observations show that Satanic Nightjar is able to utilise forest clearings and has a fairly wide elevational range, it appears to be locally common only around Anaso track and we failed to find it despite intensive surveys in other parts of LLNP. Further surveys would be needed to clarify its distribution and status in other parts of Sulawesi.
