Huge numbers of American Robins have been flocking all around Southern California in one of the largest congregations in many decades. Southern California always gets an influx of robins during the winter months, but it’s not clearly understood why they are here now in such great numbers. They started showing up in November, feeding mostly on Toyon berries. Their migration patterns are erratic, moving to and from places based on food availability. Flocks move around nomadically, eating berries from bushes and trees just like Cedar Waxwings, so it’s hard to predict where they will be at any given time. When the bounty is gone, they move on. So, enjoy the robins while they are still here. In the next few weeks they will start traveling back to their breeding grounds – possibly as far north as Canada.
