This one has me stumped. It was feeding on the grass beside a river at a park just south of Winnipeg, Manitoba, Canada yesterday evening. There were a couple of Yellow-rumped Warblers feeding there too so at first I thought it was a female or immature but on closer inspection it doesn't seem to fit the bill. This colour scheme is quite new to me. The closest I can get from my guide books is Palm Warbler, based on the rusty cap and yellow under the tail but it still looks quite different from the diagrams and photos in the guides.
