Suimanga de Macklot Leptocoma calcostetha

Large sunbird of mangroves. Male is completely covered with iridescence and can appear dark all over; look out for glistening wine-red throat and overall blue-green tones in good lighting. Female is far plainer, with a yellow belly, a pale throat, and a thin dark line through the eye. Nominate female Plain-throated Sunbird can be similar, but Plain-throated has a yellow throat, a faint eyering, a less curved bill, and more extensive yellow underparts. Gives a squeaky, ringing trill and a inflected “tslee.”
