One of my birding stops today was Greenfield Park in Milwaukee. I came across a flock of Cedar Waxwings high in a tree. I noticed what was taking place, the Cedar Waxwings would take turns coming down to what I think were Buckthorn berries and eating just a couple of them. After a couple of berries for each bird, a short rest would take place high up in the tree, then they would repeat the feeding. Probably were getting the food down in them during the rest period. The Cedar Waxwings would pick through the berries and if they were not ripe, they would spit them out. The birds put on a nice show for the few minutes I watched then on a nice sunny day, low winds and temps around 23 degrees. Images were taken on January 21, 2020.
