Red-tailed Hawk

Buteo jamaicensis

The red-tailed hawk is a bird of prey and one of the most common hawks in North America. In the United States, it is one of three species colloquially known as the "chickenhawk". The red-tailed hawk breeds throughout most of the continent, from western Alaska and northern Canada to as far south as Panama and the West Indies. The red-tailed hawk occupies a wide range of habitats and altitudes, including deserts, grasslands, coniferous and deciduous forests, agricultural fields, and urban areas. It is absent in areas of unbroken forest and in the high arctic. It is legally protected in Canada, Mexico, and the United States by the Migratory Bird Treaty. Source

Movement and weather

Each season it is first heard regularly where daytime highs are around 17°C (typically 9 to 26°C, from 18 areas). That range is wide, so temperature alone does not explain when it turns up.

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.
