Sri Lanka Gray Hornbill

Essentially a ground dove with a long tail. Pale sandy color with scaly pattern covering entire body, unlike Common Ground Dove. Look for obvious white outer tail feathers and rufous wings in flight. Fairly common from the southwestern U.S. to far western Panama. Found in pairs or small groups in neighborhoods, parks, and scrubby desert habitats. Listen for repeated soft whistled song, sounding like “no hope.” Whirring wingbeats sound almost like a rattlesnake when it takes off.

A large, stocky pigeon that is found on islands off the shore of Halmahera and far western Papua. Gray head, emerald-green back and wings, blue tail and rusty vent. The eye is red and there is a large knob-like projection on the front top of the bill. Found in a variety of forested habitats, and some wander between islands, sometimes straying to the mainland. Voice a deep, gravelly, 2-note “grrr-waw”, with the second note higher than the first. Similar Spectacled Imperial-Pigeon may co-occur but is separated by its white spectacle around the eye and lack of a knob on the bill.

Large, imperious stone-gray heron, very locally distributed and extremely rare. Note dark gray wings, pale throat patch, and white belly. Shows strong black-and-white contrast on the underwing when in flight. Inhabits waterside areas surrounded by mature broadleaf forests in foothill and mountainous areas; particularly favors pristine mountain rivers and streams. Declining due to habitat degradation.
