Description (include only what was actually seen, not what "should" have been seen; include if possible: total length/relative size compared to other familiar species, body bulk, shape, proportions, bill, eye, leg, and plumage characteristics. Stress features that separate it from similar species): Shape/structure/posture typical of Tyrannus. Notably long tail feathers, although not as long as typical adult Fork-tailed Flycatcher, suggesting an immature bird. Black cap/auriculars contrasted with white throat and submoustacial/malar, which extended back toward nape creating a collared effect. Dark gray upperparts. |

17. Similar species (include how they were eliminated by your observation): Black cap/auriuclars and dark back and tail contrasting with unmarked white underparts superficially recalls Eastern Kingbird. Eastern Kingbird eliminated by long tail; Eastern Kingbird also lacks collared look of white on throat/submoustacial area extending back toward nape. Scissor-tailed Flycatcher eliminated by black cap/auriculars. |
