- The Thick-billed Kingbird is a boisterous, noisy summer resident in southern Arizona - Known for its massive bill, black mask, and white throat, it relies heavily on dense streamside woodlands with large cottonwood and Arizona sycamore trees for breeding - They migrate north from Mexico and arrive in southern Arizona in late May, generally staying through early September - Often called "Arizona's loudest bird," they are highly conspicuous, pugnacious, and perch high in tree canopies to hunt flying insects and defend their territory - You will only find them in specific riparian corridors rather than open desert scrub - Top Southern Arizona hot-spots to see them: Paton Center for Hummingbirds; Cave Creek Canyon; San Pedro Riparian National Conservation Area; Box Canyon
