Among a dozen or so Violet-green Swallows, perched on a wire, were three I couldn't identify. Lower left might be a Barn Swallow (?), but I can't figure out the top 2. One of the Violet-greens is at the lower right for comparison. Sorry about the poor quality-- they were 60ft up or so.

Lower left is a Northern Rough-Winged Swallow. Top two- juvenile Violet-greens? or juvenile Tree Swallows? or maybe Bank swallows or more Rough-wingeds? I can't tell.

Life list 158 and counting!  ;)

 

The "five-second rule" is totally fake. Seriously, people? :rolleyes:

With the amount of white showing below the eye on the three juveniles I'd say they were also Violet-greens.

All Yellow Warblers are yellow warblers, but not all yellow warblers are Yellow Warblers

OK. What's with the white 'collar' and the coloring on the upper breast? I haven't seen markings like that on swallows before.

Looks like it's probably caused by out of place feathers.

All Yellow Warblers are yellow warblers, but not all yellow warblers are Yellow Warblers

Agree, all look like Violet-Greens based on the pale auriculars.

I'll take your word(s) for it. :) But how can I make these distinctions myself in the future? When I do a search for juvenile Violet-green Swallow, not a single image looks anything like the 2 birds at the top. And the ears don't look that pale to me. I'm useless! :P
