Forbes's Blackbird

Small olive-yellow flycatcher with black ear patch, gray crown, pinkish lower mandible, and bold, contrasting yellowish wing bars. Sexes similar. Found alone or in pairs, usually at medium to high levels in forest. Occurs in mature humid forest of montane regions. Voice a fast and descending trill “trrrrrr tzee tzee tzee tzee…” Distinguished from Marble-faced Bristle-Tyrant by contrasting black wing coverts and bold yellowish wingbars, pinkish (not gray) lower mandible, and cleaner face. Endemic to the Coastal Cordillera of Venezuela.

Brown cuckoo-dove, endemic to Enggano Island, off Sumatra’s southwest coast. Gingery-brown, with distinctively blotchy, “scaled”-looking chest and upperparts. Unique in its limited range, where it is the only cuckoo-dove. Inhabits forested and wooded areas throughout the island. Like other closely related cuckoo-doves, forages predominantly in the middle and lower levels of forest. Often keeps to dense foliage, where it can be difficult to see; listen for its song, a mellow “doo-doo-dowOOH.”

Fairly small gull, common and widespread throughout most of North America. Breeding adults are white-headed with a bold black ring around the bill; nonbreeding adults have smudgy brown markings on the head. Note pale eye and yellow legs. Immatures are mottled brownish overall; note pink bill with black tip. Found along lakes, rivers, ponds, and beaches. More common inland than most other gull species, and quite fond of parking lots and urban areas. Often in flocks. Most similar to Short-billed Gull, but larger and larger-billed. Immatures of the two species are especially difficult to differentiate, but Ring-billed is usually more coarsely mottled.
