One-colored Becard at Rio Mono
Jan Axel Cubilla found a male One-colored Becard scolding from a fruiting tree at the first bridge after the Bayano, on the road to Darién. It was similar to the White-winged Becard, but clearly lacked the white wingbars. The One-colored Becard is usually thought of as a Darién specialty, but actually it is commoner on the Bayano River Valley.
