østkongetyrann Tyrannus tyrannus

Fairly large flycatcher, dark gray above and clean white below with blacker head. Look for white tail tip. Name is somewhat misleading; it does occur over most of eastern North America but also reaches as far west as British Columbia, Washington, and Oregon. Fairly common and conspicuous; perches out in the open, often on tall trees, snags, fences, and utility lines. Watches for large insects and makes quick flights to snatch them. Listen for metallic twittering calls. Winters in lowlands of South America.
