It has a patch under its throat, but it’s not really a pronounced V shape, and the beak’s the wrong shape (shorter & stouter, more like a finch). With the help of Cornell’s “All About Birds” site, I think I can id this (and the earlier photo of a similar bird perched by a barbed-wire fence) is a dickcissel. They even helpfully say, “the breeding male is colored like a tiny meadowlark”.
