Blue-winged Warbler (Vermivora pinus)

Taken at Saratoga Battlefield on group outing but I had to shoot my 50-500 handheld which I don't do very often because it is tough to steady that way. I usually use a Bushhawk gunstock mount but had let another of our group try it out to see if he liked it. Anyway it was my first time getting photos of the Blue-winged so will post one or two anyway.
