|Male near Piraju (São Paulo, Brazil)|
The hooded siskin (Carduelis magellanica) is a small passerine bird in the finch family (Fringillidae), native to South America. It belongs to the putative clade of Neotropical siskins in the genus Carduelis sensu lato.
Hooded siskins are 10 to 14 cm in length. The male is largely green above and yellow below with a black head. It has a narrow yellow collar and a yellow rump. The tail is black with yellow sides to the base and the wings are black with a broad yellow band. Females are duller with a green-brown head, yellow-green breast and sides and a whitish belly.
The twittering song may be uttered from a perch or in flight. It is varied and fast and sometimes contains imitations of other birds.
Distribution and ecology
It inhabits woodland, savannas, scrubland, farmland, parks and gardens. It occurs from sea-level up to 5000 m. In eastern South America it is found from central Argentina north to central Brazil. In the Andean region it occurs from north-west Argentina and northern Chile north to central Colombia. There is an isolated population in south-east Venezuela, Guyana and the Brazilian state of Roraima.
It is commonly found in flocks, feeding in trees or bushes or on the ground. The diet consists mainly of seeds together with buds, leaves and some insects. Geophagy has been observed in this species.
