Bananaquit

Coereba flaveola

The bananaquit is a species of passerine bird in the tanager family Thraupidae. Before the development of molecular genetics in the 21st century, its relationship to other species was uncertain, and it was placed with the buntings and New World sparrows in the family Emberizidae, with New World warblers in the family Parulidae, or its own monotypic family, Coerebidae. This small, active nectarivore is found in warmer parts of the Americas and is generally common. Source

Movement and weather

Each season it is first heard regularly where daytime highs are around 29°C (typically 27 to 30°C, from 7 areas). That holds across 50° 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 South America ranged from 22°S in November to 5°S in February, about 1,900 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.
