Slaty-backed Flycatcher

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.

An attractive, fierce-eyed babbler of tropical montane rainforest. Black head with thin, white eyebrow, white from the throat to mid-belly, contrasting strongly with remaining dark maroon body. Note the slightly decurved, yellow bill. Forages in noisy, small groups through the midstorey. Unmistakable if seen well. Calls variable, but commonly gives a soft “wu-tu” followed by a rising “whit!”, quickly repeated. Groups also give an excited chatter.

Medium-sized raptor of montane forests. Adult is dark brownish-black above and has heavily black-streaked white underparts. Flying adult shows broad, rounded wings and a single broad white band on the tail. Lacks the overall buffy brown tones of the much smaller adult Wallace’s Hawk-Eagle. Immature is very similar to Wallace’s but has thinner tail barring; immatures are best distinguished by altitude (Blyth’s favors higher elevations than Wallace’s) and size. Small crest is not visible in flight but may be held erect when perched.
