Rufous-bellied Thrush

The rufous-bellied thrush (Turdus rufiventris) is a songbird of the thrush family (Turdidae). It occurs in most of east and southeast Brazil from Maranhão south to Rio Grande do Sul states, Bolivia, Paraguay, Uruguay and central regions of Argentina. This species is named after its distinctive reddish-orange underparts. Rufous-bellied thrushes can reach a length of 25 cm and weigh up to 68 g (male) or 78 g (female), though weights of about 59 g for males and 64 g for females are more usual. Contrary to what one might expect from the rather marked weight difference, the females are not larger, only plumper; their tarsus is actually a bit shorter than that of males on average.
