Grande Comore Bulbul

This warm brown forest dweller is similar to many other foliage-gleaners and treehunters. Look for the relatively bright orangey throat with streaking on the breast. The bill is all dark. Also note the plain head without an eyebrow. Found in montane forests from 900 to 2500m, where it moves at low to middle heights. Seen singly or in pairs, often with a mixed-species flock. Song is a harsh series of paired notes.

Medium-sized flycatcher with a plumage pattern—brownish above, yellow below—that recalls Tropical Kingbird, but Sulphury Flycatcher is much darker gray on the face and head and has a contrasting white throat. Inhabits a variety of forest types but is most common in flooded and edge habitats with many palms—especially common in Moriche palm stands in savanna regions. Generally sluggish; usually in pairs, which take inconspicuous perches and sally to surrounding vegetation for insects (unlike kingbirds, which sit on exposed perches and tend to catch insects from the air). Highly vocal; distinctive, loud calls have electric quality and are usually heard before birds are seen.

Large scoter, with distinctive white patch on wing. Dark chocolate-brown overall; males are darker than females and have small white mark under eye. Note bill pattern: mostly yellow with a dark knob on top and a subtle pinkish tip. Females have two rounded white patches on face. Breeds on ponds, lakes, or rivers in woodland or tundra across much of northern Europe. Winters mainly in coastal waters, sometimes in large flocks. Occasionally found on large inland lakes during migration. Dives frequently, feeding on mollusks and crustaceans.
