In the 1970s along the 1-80 highway in Keith County, Nebraska, drivers started noticing large numbers of
dead swallows on the road (Brown & Brown, 2013). This led to a 45-year long study on swallow roadkill to
figure out why this was happening.
Cliff Swallows traditionally built their nests on vertical cliff faces. However, with the expansion of roads,
they have adopted many bridges, overpasses, and culverts as their colonial nesting sites. Their nests are

catch insects for food. In this new c
