During the fall 2000 migration, I decided to do some mist netting at Oliver State Recreation Area in Kimball County. My main emphasis was to document the occurrence of several species of Empidonax in western Nebraska. limited netting there in fall 1999 was not very successful, but I was more optimistic this year. With that in mind, I obtained the necessary federal and state permits and netted on four dates (26 August, 31 August, 7 September, and 20 September), each chosen to be immediately after the passage of a cold front.
