Every time I try and say this bird's name, I tie myself up in knots. Pronothotary is a common one. Prothanorty.... Dammit. Bloody amazing bright yellow bordering on gold warbler. In these cases I find that a photo is worth a thousand words. This is of a breeding bird in Ohio, viewed from the raised boardwalk at Magee Marsh (which, btw, is superb). This is the female, the male is even brighter, and simply glows.
