A new species of Melanocharis berrypecker (Melanocharitidae) was discovered during a recent ornithological expedition to the Kumawa Mountains in West Papua, in the cloud forest at an elevation of 1200 m. It has been named Satin Berrypecker (Melanocharis citreola)

Eurasian Blackcap used to be a scarce wintering bird in the UK and Ireland, but the occurrence of overwintering Blackcaps has increased along with the popularity of bird feeding. These birds migrate from central Europe, in which has become a new migration route to spend the winter near the artificial feeding stations.

Most of us feel soothed and relaxed when walking through nature. One of the reasons is because listening to birdsong produces stress relief, and a feeling of pleasure or well-being, which directly affects our health.

Stories about rediscoveries of ‘lost’ species make for exciting ornithological news, and Asia has captured much attention for several recent discoveries. All the previous cases, however, are obscured by the magnitude of the present case: the rediscovery of the Black-browed Babbler.

New research is challenging the assumption that previous migratory experience is necessary for birds to correct themselves when blown off course during migration. A study of Eurasian Reed Warblers shows birds can use a combination of cues derived from the Earth’s magnetic field to detect a displacement, even if all of these cues are of unfamiliar magnitude.

A deeper look at how ongoing biological expeditions in the remote montane forests in southeast Asia, coupled with acute hearing (good ears!) and professional sound recording analysis, led to the discovery of 10 new taxa and as-yet-undescribed leaf warbler on the remote islands of Indonesia.
