Green-backed Tit

Small black-and-white eagle. Has a compact, powerful shape, and the hint of a crest. The upperparts are black, and there are heavy black markings on the underparts and evenly across the underwing. Found in thick woodland and forest. Soars frequently. Call is a loud, repeated “kwee-ya.” Similar to other hawk-eagles, but has more heavily marked underparts. Easily separated in flight, when Ayres’s Hawk-Eagle shows black barring across the entire underwing.

Widespread and abundant in cities, neighborhoods and farms. Avoids dense woods. Flocks cluster in dense bushes, bustling around and chattering to one another. Males have smart black bibs, bright rufous napes, and stunningly patterned wings with brilliant buffs and browns. Underparts are pale pearly-gray. Females are plain brown with cute face and lighter eyebrow. Native to Eurasia; introduced to much of the rest of the world.

Distinctive warbler with bold black-and-white stripes over entire body. Adult males have black throat and cheek; females and immatures have white throat and paler cheek. Creeps along branches like a nuthatch, searching for insects. Breeds in mature deciduous or mixed forests; winters in a wider variety of wooded habitats as far south as northern South America. Listen for high pitched “squeaky-wheel” song. Breeding male Blackpoll Warbler is potentially confusing, but note different behavior and face pattern.
