Bird ID

I posted a photo on Man and Nature and ID the bird silhouettes as robins. One comment was made they had never seen that many robins together. Although I've seen large groups of robins I have never seen that many at once.
Can an ID be made by silhouette.
An opinion if you have time.

Photo on Man and Nature, Prairie Sunrise, is the title.

I'd be more inclined to believe these are starlings or members of the blackbird family. Blackbirds, cowbirds, starlings, and grackles are famous for forming large flocks while robins are not. This is more appropriate habitat for blackbirds than robins. The shape of some of the birds in the flock show pointed wings and short tails - better fro starlings than robins. they could even be meadowlarks (members of the blackbird family) based on that shape and the habitat.

Nice photo, Larry. I agree with Richard. The photo is ambiguous, but the locale implies a member of the blackbird family or perhaps starlings. Robins in migration do move in flocks, but they do not cluster in tight groups like this. A mixed flock of blackbirds would also explain the variation in shapes.

My original thought was blackbirds, too.
But I thought I could see robin silhouettes in the enlarged original. But that was just a perception.
Not a big deal and thanks for the time.
