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.
