The record stations in Washington for the pale, southern race are all in arid places and the dark, coastal race is a forest animal. Most of the specimens taken by me (all of the dark race) were in clearings or along roads through timber near the crests of hills. They appeared relatively late in the evening, after the big-brown and the silver-haired bats had been in the air for some time. Often they were taken in company with Myotis lucifugus and Myotis yumanensis. They were appreciably larger than those species and their flight was slower and less erratic. They usually flew in relatively straight lines or large circles at from ten to forty feet from the ground. At Lake Kapowsin, Pierce County, they were attracted by swishing a long pole in the air. At Renton, King County, one was shot as it hunted insects at a city street light several hours after dark.
