Ok all you birding by ear experts. I'm at the Lake of the Ozarks this week and ever since I've been here I've been hearing a trill that sounds just like the IBird Pro app call of a Palm Warbler. Since it's a migrant I kinda thought they'd have moved through by now. It's described as a dry trill. Any thoughts?
