These tanagers are mainly found in semi-open habitats including plantations and open woodland, but some will venture into towns. They feed from medium to high levels in trees, taking mainly fruit, with some nectar, and insects which may be taken in flight.
The pair builds a usually well concealed cup nest, but the female incubates alone. The Blue-gray and Palm Tanagers will nest in buildings.
Thraupis tanagers have squeaky call notes and songs which consist of 5-10 repetitions of a single or double note.
