"The previous 'Patterns from eBird' featured animated maps of Northern Cardinal based on predictive modeling. This time we'll take a look at how these maps predict migration in Eastern Phoebe, a widespread eastern species. Eastern Phoebe is the hardiest flycatcher in the United States and Canada, and in some areas it returns to the breeding grounds more than a month earlier than any other flycatcher. Its wintering range is largely within the United States, so these animated maps reveal its entire annual cycle."
