Tracks of the vessels during times that the vessels accompanied groups of killer whales 

 (Orcinus orca) 2002-2004. (A) tracks of vessels following resident killer whales in the 

 Eastern Aleutians during summer; (B) tracks of vessels following transient killer whales 

 in the Eastern Aleutians during summer; (C) tracks of transient killer whales near 

 False Pass- Unimak Island during spring. 



2003 and 2004 (Fig. 2B). The remaining 51 individuals 

 were photographed during the summer field season when 

 encounters with transient killer whales were relatively 



infrequent in the eastern Aleutians from Unimak Pass 

 west to Umnak Island (Fig. 2C). There were only six 

 transient whales (less than 4% of the total identified)
