The tremendous energy which drives small buds toward their 

 breeding grounds in spring is well illustrated by the way in which 

 some of them overshoot their destination. Witness the occurrence of 

 the eastern race of the white-crowned sparrow on Fletcher's Ice Island 

 (T-3) on June 16, 1957, when it was at 82°37 / N., 99°50' W., only 150 

 miles from the North Pole and some 2,000 miles beyond the nearest 

 nesting habitat of the species, as reported by Spencer Apollonio (1958).
