During the summer of 1958, 16 Purple Martins were used in a series of homing experiments at the University of Michigan Biological Station. The birds were released at distances ranging from 1.75 miles to 234 miles. The rate of return varied greatly. The most rapid return was a nocturnal flight of 234 miles in 8.58 hours. One hundred per cent of the martins returned from the homing flights. This material has been compared with the available homing data pertaining to the Hirundinidae.
