Basileuterus

Basileuterus is a genus of birds in the family Parulidae, commonly known as New World warblers. The genus was introduced by the French ornithologist Charles Lucien Bonaparte in 1850. The name Basileuterus is derived from the Greek words "basileus," meaning king, and "leuteros," meaning thin, referring to the thin bill of these birds.

The genus Basileuterus includes several species, all of which are native to the Americas. These species are typically small to medium-sized birds with vibrant plumage and distinctive songs. They are known for their agile flight and their ability to perch on thin branches, which is reflected in their genus name.

Basileuterus species are often found in a variety of habitats, including forests, woodlands, and scrublands. They are insectivorous, feeding on a diet of insects and spiders. Many species are migratory, traveling long distances between their breeding and wintering grounds.

The genus Basileuterus is an important component of the avian fauna in the Americas, contributing to the biodiversity of these regions. However, like many bird species, they face threats from habitat loss and climate change. Conservation efforts are ongoing to protect these birds and their habitats.
