American Robins: Overwintering in MN

American Robins are known to overwinter in Minnesota in modest numbers. I have occasionally seen a Robin or two over the years. However, this year I have seen quite a few. Last week, during the sub-zero temperatures, I saw three separate flocks (on the same day!) feeding on the berries of Hackberry trees (Celtis occidentalis). Each flock numbered about 24 to 36 birds.



My dad reported several American Robins eating the small, red fruits on his Eastern Wahoo tree (Euonymus atropurpurea) last week. He adds, "This is the third winter that the female Cardinal has eaten berries from this tree." This is exciting to know because I have not heard many reports regarding what birds feed on the fruit of Eastern Wahoo.



I am glad these birds are finding food at this time of year. If American Robins are shifting their winter ranges farther north, it is not clear. I have heard reports that birds are more sensitive to climate change. Birds are more sensitive to climate change whether the shifting is due to short term weather patterns or long terms changes. Northern Cardinals shifted north years ago and we enjoy seeing them during our winter seasons.



All sightings were in Saint Paul, MN

Hi Eric, I have also I had great luck seeing Robins in my yard by keeping a unfrozen water bowl for them.
