Curl-crested Jay

Breeding males have obvious white blaze on forehead and broad green slash behind eye. Females are plainer brown with rusty sides. Females are very difficult to distinguish from female Eurasian Wigeon; note colder grayish-brown head on American that contrasts with warmer orangey sides. Also look for brighter white, not gray, underwings in flight, but this can be difficult to judge, especially at a distance. Widespread and common in North America, occasionally wintering as far south as northern South America. Typically in flocks on lakes and wetlands, often grazing in nearby fields. Regular vagrant to Europe.

A sleek, medium-large, gregarious species of woodlands that sometimes ventures into agricultural and urban areas. Its overall green plumage, long, pointed tail, and stout bill eliminate all other species in range. In overflight, it often appears green with a red slash on each forewing. Most common call is a series of squeaks that takes on a twittering quality when given by an excited flock.

A gray starling with a contrastingly black head, a small tuft above the bill, a white wing patch, a pale eye, and yellow legs and beak. Juvenile browner than adult, with pale brown head. Groups inhabit open country in lowlands and foothills such as croplands, cultivated areas, and grasslands, frequently feeding on the ground, sometimes around livestock. Native to Sulawesi, introduced in Borneo. Differs from Crested Myna in white vent and from Javan Myna in paler belly; both of those species introduced on Borneo too. Vocalizations include rattles and whistles.
