The Crimson-fronted cardinal (Paroaria baeri), is a species of tanager in the Thraupidae family. It was formerly placed in the Emberizidae and is not very closely related to the cardinals proper (Cardinalidae).
It is endemic to Brazil. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist shrubland. The crimson-fronted cardinal is relatively close to 16.5 cm, and is most often slim with a rounded crown. It's voice is rather harsh and vigorous and includes descending, harsh whistles. Very little is known about its diet, however it most likely eats insects and few fruits.
Breeding season is often thought to be October through January, with some nests accompanied by eggs found in mid-December.
