Southern Crested Guineafowl
Guttera edouardi
A large-bodied, small-headed, black gamebird perfectly lined with rows of hundreds of bluish-white spots. It has a ridiculous-looking plumed “toupee” above the naked face, which features an ivory-colored bill and a blood-red eye. The facial skin color varies geographically, and can be mostly blue-gray with small patches of red and white, or predominantly blue-gray with a large white patch on the back of the neck. A broad band around the base of the neck is unspotted black. It prefers forest and thickets, where it forages on the ground for berries, seeds, and other plant matter. The similar Helmeted Guineafowl differs by its lack of feathered crest and its having a bone-like casque on top of the head instead. The alarm call is a series of rattling, agitated notes that speed up and slow down; similar to the call of Helmeted Guineafowl, but with a tinnier quality.

Roraiman Antwren
Herpsilochmus roraimae
A common but inconspicuous bird of tepui forest canopy. Usually seen from below; note long shape accentuated by heavy bill and long tail. Male is gray above and white below, with a black crown, bold white eyebrow, wing spotting, and extensively white undertail. Females are similar to males but have more brown tones in plumage. Forages sluggishly in canopy of tepui foothill forest, searching for insects along branches and in leaf clusters. More common at lower elevations than many other tepui endemics (sometimes below 500 m). Usually in pairs and best detected by voice; often follows mixed-species flocks but also found away from them. Contact call is a rubbery smacking, often doubled and repeated in long series by members of a pair. Song is a hoarse, emphatic series of laughing notes, decelerating and dropping slightly in pitch. Similar to Spot-tailed and Todd’s antwrens (and may overlap with latter at lower elevations) but substantially larger, with bolder markings and more white in tail; song is similar to that of Todd’s but longer and hoarser.
Streak-chested Antpitta
Hylopezus perspicillatus
A plump ball on sticks. Fairly common and easily heard, but shy and rarely seen in the open. Striking plumage: bold buffy eyering, gray crown, black mustache stripe, thick black and white streaking on underparts, and buffy spots on wings. Singles or pairs are found on or near the ground in mature lowland forest from Honduras to Ecuador. Occasionally perches higher when singing. Listen for its song, a short series of plaintive whistled notes.
American Herring Gull
Larus smithsonianus
Common and widespread large gull found throughout North America. Adults have a fairly pale gray back, pale eye, and dull pinkish legs. Takes four years for immatures to progress from mostly brown to fully white and gray adult plumage; intermediate plumages are often mottled and messy. Usually shows a dull pinkish base to the bill by the first winter, and develops a pale eye by the second winter. Some immature birds can fade to almost white, especially in their first or second summer, but they always show darker wingtips. Occurs inland and along the coast, frequenting fishing boats, beaches, lakes, and landfills. Often forms large flocks with other gulls.
