Grande Comore Drongo

Restricted to Isla Robinson Crusoe in the Juan Fernandez Islands where no similar species occur. Uncommon and declining. Favors remaining patches of native scrub and low woodland, mainly at elevations above the town. Usually in pairs, hopping low in vegetation; can be curious. Identified by streaked breast and staring pale eyes; wispy crest is often held flattened.

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.

A barrel-chested snipe with a dark brown back and frosty-pale face and belly. Breeds in far northern bogs and near streams, where it may even winter if water remains open; the only snipe likely to be seen in this kind of habitat in the colder months. Also winters along rocky streams and artificial canals with flowing water. Much darker and more silvery-gray in coloration than other snipe species, which are a paler brown overall. Flies straight and powerfully; does not zigzag in flight like Common Snipe and Pin-tailed Snipe.
