 Deltarhynchus is similar to the genus Myiarchus , but is distinguished from it by a broader and shorter bill , more rounded wings , a different face pattern , pale cinnamon wing and tail edgings , voice , streaking on the chest , and the bird 's skulking habits . The flammulated flycatcher 's generic name is derived from the Ancient Greek words delta , which means " delta @-@ shaped " or , in this case , " wedge " , and rhynchos , which means " beak " . Its specific epithet is derived from the Latin word flammula , which means " little flame " . The flycatcher has no subspecies .
