While involved in avian and fisheries investigations in the Yukon Territory for Foothills Pipe Lines (Yukon) Ltd. and Foothills Pipe Lines (South Yukon) Ltd., we had opportunities to observe and discuss Dipper (Cinclus mexicanus) feeding behaviour. On 30 March 1978 Young encountered two Environment Canada employees who were studying flow characteristics of Engineer Creek, 65°21’N, 138°19’W. The employees indicated that in mid-December 1977 they observed a Dipper emerge from the creek with a “small” (less than 7 cm) fish in its bill. When they approached the bird, it flew off, dropping the fish, which was identified as an Arctic Grayling (Thymallus arcticus).
