Another seed-eating bird found only in Central & South America, the Blue-black Grassquit (my gallery link) with the one above on a little bush or plant in the cow pasture across the street from me. This male was jumping straight up in the air from this bush about two feet or 60 centimeters as a courtship display, which I’m yet to catch an action shot of! 🙂 See more from there and from 6 other Costa Rica locations in my above-linked gallery. And/or read more about them and see their distribution map on eBird and a very good article on Wikipedia.
¡Pura Vida!
