Letter from C.A. Stewart to E.L. Kozicky, Margaret Jones, George E. Crossley, J.F. Moore, and Fred Hall regarding a revised check list for the birds of Iowa, February 3, 1950. Stewart suggests the best way to revise the check list to include the most up-to-date bird ranges is a survey of bird populations completed by members of the IOU. Included with the letter are instructions to be used in making out the frequency report and an example of a 'Report of occurrence frequency and breeding status of birds of Iowa' form completed by Stewart.
