As Rubythroats migrate southward this fall, how quickly will they travel? Based on banding re-encounters, one flew 1,200 miles in 12 days (100 miles/day). Another flew 335 miles in 7 days (48 miles per day). Overall, their average rate of travel is estimated at fewer than 25 miles per day. Where will a bird visiting your feeder today be a week from now, if it travels 25, 50, or 100 miles per day?
