The present brief account is intended as a progress report on the status of the bird trapping station located in the back yard at my home in Iowa City. This station, consisting of two government sparrow traps, was established in 1920 and has been in almost constant operation since that time. An "Everset" trap was added to the complement of traps in 1925.
