Cuban Martin
Progne cryptoleuca
A graceful aerial feeder found over a wide variety of open habitats, especially near water, including marshes and towns. Often chooses exposed perches including power and telephone lines in villages. Commonly found in flocks of up to twenty birds, sometimes mixing with other swallows and martins. The adult male is entirely glossy purple-blue and is inseparable in the field from male Purple Martins. The male Caribbean Martin can be distinguished by its bright white belly. Female and immature Cuban Martins resemble females and immatures of both Purple and Caribbean Martin. Purple Martin in such plumages can be identified by a scaly breast pattern and often fine streaks on the belly, which is lacking on female and immature Cuban Martins. Female Cuban Martins are probably not safely separable from Caribbean Martin, though on average the Cuban Martin has more restricted brown on chest. Note that Caribbean and Purple Martins are not present in this species’ range from March to September, which can help eliminate confusing species. Calls include a harsh “churr,” a buzzy “zwick-zwick,” and a musical buzzy burbling.
Identification
Adult Cuban martins are 18.5 cm in length, with a forked tail and relatively broad wings, and weigh 40 g. Adult males are a glossy blue-black with contrasting white lower underparts. Females and juveniles are duller than the male, with grey-brown breast and flanks and white lower underparts.<p>Adult male Cuban martins can be distinguished from adult male Caribbean martins by their dark bellies: Caribbean martins have a prominent white patch on theirs. Adult females and immatures aren't as easily distinguished.<p>On the other hand, adult male Cuban martins and Purple martins cannot be reliably distinguished in the field. Adult female and immature Purple martins have a scaly breast pattern which can be used to distinguish the two species.<p>Unlike these two similar species, the Cuban martin is endemic to Cuba and Isla de la Juventud. Purple martins and Caribbean martins are migratory species that are only present in the Cuban martin's range during winter.

Behavior
The Cuban martin nests in cavities in banks and buildings, or old woodpecker holes. 3-6 eggs are laid in the lined nest, and incubated for 15 days, with another 26–27 to fledging. Just as the purple martin, this species may compete with other passerines for nesting cavities. In particular, the main foe is the house sparrow in urban areas, where they mostly use man-made structures, whereas in more rural locations Picidae holes in coconut trees are favored, and there is less competition with the sparrows.<p>Cuban martins are gregarious birds which hunt for insects in flight. They are often found in large, sometimes mixed flocks of up to 20 birds. Their call is a gurgly chew-chew.<p>Despite being considered endemic to Cuba and Isla de la Juventud, occasional vagrant individuals have been reported in Florida.

Cinereous Bulbul
Hemixos cinereus
Large dull bulbul with a bright white throat and a low, bushy crest. Gray-brown above and smudgy white below, with a grayish wash on the breast. Note distinctive squared-off dark patch between eye, throat, and bill base. Mainland birds have fairly dark upperparts, while Bornean birds are paler above, with yellowish-green wings and tails. Primarily inhabits montane and submontane broadleaf evergreen forests, though occasionally also in lowland areas. Sociable, often occurring in both single- and mixed-species flocks, particularly around fruiting trees. Not very musical, but vocally varied, giving nasal, plaintive “wheers”, high-pitched “deees”, and repetitive, colorless “djeer, djeer, djeer.”
Humblot's Sunbird
Cinnyris humbloti
A small sunbird with a relatively short, slightly downcurved bill. Males are colorful, with blue and purple iridescence on the head and breast and orange and yellow on the belly. Females are fairly drab, with a dark-spotted white breast and a yellow belly. Found in all habitats on the islands of Grand Comoro and Moheli. Found alongside Madagascar Sunbird, but much smaller, with a shorter, weaker bill. Males further separated by their paler yellow belly, and females by having less streaking on the underparts and no conspicuous pale eyebrow. The song is a typical sunbird jumble of squeaky notes, and the call is a rising whine.
Henderson Petrel
Pterodroma atrata
A typical uniformly grayish-brown petrel with pale mottling at the base of the bill that gives it a somewhat “frosted” facial appearance. Pale bar along the leading edge of the underwing between the body and elbow is evident in flight. Highly pelagic, visiting land only to nest. Similar to Kermadec Petrel, but lacks the white primary shafts in the upperwing of that species and is overall more uniformly colored. Providence Petrel is similar but appears much heavier-chested and paler-faced, with more extensively mottled gray-brown tones across the body. Herald Petrel is very similar, but has much more contrasting dark-and-light underwing pattern. Henderson Petrel is silent at sea.
