Rufous Whistler

Pachycephala rufiventris

The rufous whistler is a species of whistler found in New Caledonia and Australia. Predominantly a reddish-brown and grey bird, it makes up for its subdued plumage with its song-making ability. Like many other members of the Pachycephalidae, it has a variety of musical calls. Source

Movement and weather

Each season it is first heard regularly where daytime highs are around 19°C (typically 17 to 22°C, from 9 areas). That holds across 20° of latitude, which suggests its timing follows temperature more than the calendar.

Over the weeks it was present in the past year, its centre in Oceania ranged from 35°S in November to 26°S in August, about 1,000 km apart.

Arrival dates

The week it was first heard regularly in each region, after at least six weeks away. Dates differ from south to north, so a region has a range.
