Dolphin Gull

Leucophaeus scoresbii

Handsome, distinctive dark gull of southern South America and Falklands. Favors rocky coastal areas, but also ranges to lakes near the coast. Fairly common; can be confiding at harbors and waterfronts. Feeds mainly by scavenging and often gathers at sea mammal and seabird colonies. Adult has diagnostic smoky gray body, thick red bill, and red legs. Immature and nonbreeding adult have a dark hood, but immatures also have paler pinkish legs and bill, and a black band on the tail.

Identification

The dolphin gull (Leucophaeus scoresbii), sometimes erroneously called the red-billed gull (a somewhat similar but unrelated species from New Zealand), is a gull native to southern Chile and Argentina, and the Falkland Islands. It is a coastal bird inhabiting rocky, muddy and sandy shores and is often found around seabird colonies. They have greyish feathers, and the feathers on their wings are a darker shade. Dolphin gulls have a varied diet, eating many things ranging from mussels to carrion. The modern scientific name Leucophaeus scoresbii, together with the obsolete common name Scoresby's gull, commemorates the English explorer William Scoresby (1789–1857).

Other Birds

Ethiopian White-eye

Ethiopian White-eye

Zosterops poliogastrus

A small, sharp-billed warbler-like bird. Note the yellow throat and the broad white spectacles around the eyes. Found in montane forest and lush gardens and scrub, usually in hyperactive flocks. Similar to Abyssinian White-eye, and some individuals are difficult to separate, but generally shows a broader eye-ring. Most common call is a high-pitched rising rattle. Song is a subdued, chatty sequence of “chew” notes.

Inambari Gnatcatcher

Inambari Gnatcatcher

Polioptila attenboroughi

Recently described, inconspicuous and rarely seen bird of rainforest canopy. Small and slender with a long tail; mostly dark gray with a broken white eyering, white belly, and white outer tail feathers. Inhabits canopy of tall forest, especially in regions with sandy soils. Usually seen with mixed-species flocks as it forages actively in outer foliage, sallying for insects and gleaning from leaves, moving long tail from side to side like other gnatcatchers. Thin and indistinct call notes are easily overlooked among calls of other species in flocks, but distinctive shape, active behavior, and long tail with extensive white should clinch identification. Extremely similar to other gnatcatchers of the Guianan Gnatcatcher complex, but no overlap in range. Distinguished from Tropical Gnatcatcher by uniform gray body plumage and lack of a black cap, and from Tooth-billed Wren by slimmer shape and smaller size, lacking any black barring in the plumage.

Yellow-necked Greenbul

Yellow-necked Greenbul

Chlorocichla falkensteini

A medium-sized greenbul of thickets and tangles that prefers edge and semi-disturbed habitats. Most often seen in pairs or small family groups, but it will occasionally join other species in flocks. Gray below except for a bright yellow throat, and uniformly yellow-green above with reddish eyes. Most likely to be confused with the similarly named Yellow-throated Greenbul, which usually has a paler whitish throat in areas where the two species overlap. Yellow-necked Greenbuls can be distinguished by their uniformly gray underparts, brighter olive-green upperparts, dark red eyes, and consistently bright yellow throats. Voice is a variable subdued chatter, “kur-ku-kurkwu.”
