Olive Flyrobin

Fairly large flowerpiercer, almost all blue with black mask and red eye. Bill is upturned with a hook at the tip, typical of a flowerpiercer. Sexes alike. Fairly active like a warbler or small tanager, often following a mixed-species flock but sometimes foraging separately. Could be confused with Blue-and-black Tanager but note bill shape and blue (not black) wings. Separated from other flowerpiercers by bright blue color combined with black mask. Quite common and widespread in the Andes from Venezuela to Bolivia, usually above 2,000 m. Feeds on fruit, nectar, and insects.

A bulbul-sized olive-brown bird that sports a diagnostic all-red bill and a red eye surrounded by a fleshy yellow wattle. The juvenile lacks the bright bill and eye coloration. Small groups occur in savanna and farmland, where they require large wild ungulates and domestic stock to forage on; they clamber agilely over host mammals, gleaning ticks, mites, and other ectoparasites, and occasionally drinking host blood. As they fly between large mammals, they give a distinctive “tsik-tsik” call. The similar Yellow-billed Oxpecker differs from Red-billed Oxpecker by having a yellow bill base and pale rump and lacking an eye-wattle.

Rather large, wholly dark petrel. Breeds in New Zealand and ranges across the temperate South Pacific to Chile, where it is uncommon to locally fairly common in the Humboldt Current and fjords. Often found with much commoner, but very similar White-chinned Petrel and is not easily identified unless distinct black bill tip of Westland can be seen (White-chinned has pale bill tip). Slightly smaller Parkinson’s Petrel looks very similar to Westland, but favors warmer tropical and subtropical waters and has a smaller, more rounded head and slightly slimmer bill.
