Polynesian Storm-Petrel

Striking small seabird of cold subantarctic waters; some birds range farther north in winter (mainly May–August). Despite the name, its bold white belly is the most obvious feature that separates Black-bellied from slightly smaller Wilson’s Storm-Petrel. Most birds have a black stripe bisecting the white belly patch, but the stripe is often hard to see. Flight style often eye-catching; splashes belly down in the water and kicks its feet to change direction. Compare with the very similar White-bellied Storm-Petrel of subtropical waters, which occurs mainly to the north of Black-bellied’s range.

Deep blue ground-dweller with shining forehead and shoulder patches; belly can appear mottled blue-and-black in the right lighting. Inhabits foothills and montane forests, where it sticks closely to water, especially rocky streams and smaller rivers with overhanging vegetation and rocky ledges. Song is an eerie and human-like series of variable, deliberate-sounding whistles. Call is a high thin “tseeeeee.”

A small, largely green pigeon with bold, scattered pale markings on its wings. Adults show largely pale bills while immatures have dark bills. Small groups found in varied habitats with trees, from forests to open woodlands. In most of its range it is the only Treron green-pigeon, but where it overlaps with Pink-necked Green-Pigeon, note the extensive pale markings on the wing of Flores Green-Pigeon and the absence of a pink-orange breast patch. Song is a series of soft whistles, “woo-wo-OW,” rising at end. Also gives harsher guttural notes.
