They nests in trees, building a cup nest. The female usually lays 3-6 eggs, but the two other groups, which breed in mangroves, lay fewer eggs, as would be expected for tropical races.
These birds feed on insects and spiders, but northern races will also take some berries. As they are visitors to my bird feeders and will take suet cake offerings.
