ABSTRACT Median spring arrival dates for 74 avian species migrating through east-central Illinois were recorded around Urbana, Champaign County, 1903-1922, and near Charleston, Coles County, 1965-1987. Only 11% had an expected lag of 2-3 days later in their median arrivals in Urbana than 74 km farther south in Charleston; arrivals of individual species varied by 12 days earlier to 30 days later in Urbana than decades later in Charleston. Changes in climate or in population size over time may have contributed to marked differences for some of these species as well as for several others where yearly observations were rare at one site or the other. For a few nesting species availability of key bottomland forest habitat in Coles County but not in Champaign County could explain their infrequent records or late arrivals in Urbana.
