The Black-billed Cuckoo is an uncommon breeder in northern IL and IN, northward. They are usually found in shrublands, grassland hedgerows, or woodlands with moderate understory. This species can be very difficult to detect and BCN eBird records are insufficient to produce accurate trends. BBS data indicates a a significant annual decrease of -2.9% in the upper Midwest. Trends for this species may change in response to the recent arrival of gypsy moths in the region. Photo: © Eric Secker
