Желтошапочная корольковка Basileuterus culicivorus

Small, rather active warbler of tropical evergreen and semi-deciduous forest in foothills and lowlands. Often in pairs at low to middle levels in shady forests with fairly open understory. Regularly seen with mixed-species feeding flocks. Like other tropical warblers, sexes look alike: overall grayish above and yellowish below with weak blackish head stripes that border a dull and easily overlooked golden or dull orangish central crown stripe.
