The plumage is soft and lax, much as in the owls; the birds have the same noiseless lliglit, as well as, in many eases, nocturnal or erepuseular habits ; and they sometimes bear an odd resemblance to owls in their general appearance. An evident design of the capacious mouth, is the caiiture of insects ; the active birds ijuarter the air with wide open mouth, anil their minute prey is reailily taken in. But they also secure larger insects in other ways; and to this end the rictus is fri'Oiientlv stroniilv bristled, as in the I'l/rainiidir. Our two genera are readily discriminated by the enormous rictal bristles, roumled tail and comparatively short wings of Antronlovnis, ihc slight bristles, {^ /^ [} foiked tail and long pointed wings of ('/lordcilrs; they each repre- ^ (j ^ sent one of the two sections of the subfamily.
