This bill houses a semi-tubular tongue as mentioned above, which is unique in the genus. These may be useful adaptations for their rainy weather
Hower feeding, but would seem ill-adapted for the characteristic flycatching of the breeding season (Gardner 1925). It is doubtless useful in other seasons. as will be discussed later. Aside from the Cape May, all other species differ in bimeasurement by only a small fraction of a millimeter.
