American Robin and The Common or Eurasian Blackbird

Common or Eurasian Black Bird

American Robin

My amateur observation of these 2 thrushes that look nothing alike but in my observation their behavior and vocalizations are very similar.

On my first evening in Germany I took a walk through a park and bicycle path to do some birding. The second bird I saw was the Common Blackbird. Later after walking for about an hour and it was getting dark I heard in the bushes a familiar sounding call. It sounded like the call of an excited American Robin. Since I didn't see the bird I assumed it might be a European Robin, a bird I later found in my opinion to not have much in common with the American Robin. The next day I walked through the  Nuremberg Cemetery and there found that the bird I heard the night before and assumed to be a European Robin was actually the Common Blackbird.

Throughout the remainder of our visit I watched the Blackbirds birds fly over in groups, forage on lawns and gardens just like our American Robin.

Though they don't look a lot alike I found them to be very close in sound and behavior. I would love comments from any of you who is more familiar with both of these species than I am.
