The song and call of this individual bird can be heard through the player below.
The sexes are alike. The adult Red-capped Cardinal is 16.5 cm long and weighs 22 g. It has a crimson head and black upperparts, apart from a white partial collar extending up the neck sides from the white underparts. The throat is black, extending to a point on the upper chest.
Song is a hesitating, repetitive series of warbled notes 'cheeber wee? cheeber wee? cheeber.
The call is a wheezy 'rhee?' and 'chew' and a rapid chatter in flight
