Piping Crow

Small seabird of coastal areas of the North Atlantic and Alaska. Breeding plumage is entirely black with bold white patch on wings and bright red legs. Changes dramatically in winter to whitish overall with some dusky markings on body and black wingtips. Often found in shallower coastal waters including from shore. Dives to hunt for fish and invertebrates. Nests in crevice or burrow in a cliff or around large rocks.

Small glossy crow, common in northwest Mexico; endemic. Occurs in towns, villages, rubbish dumps, farmland, and semiopen areas with hedges and taller trees; often near water. Roosts locally in mangroves (at times in thousands). Social and usually in flocks, at times of hundreds. Most likely to be confused with male Great-tailed Grackle, which has pale eyes and longer and keel-shaped tail (shed in late-summer molt). Calls are high, nasal caws.

Rather stocky, all-dark ibis of wetlands and lakes in high Andes; also wanders to coastal lowlands, where can be locally numerous. Usually in small groups. Feeds by probing with its downcurved bill. Breeding adult has dark chestnut head and neck, and red face. Nonbreeding and immature have whitish streaking on head and neck, and duller face. In flight, feet project only a short distance beyond tail tip. Compare with more slender and long-legged White-faced Ibis, but no range overlap.
