Cold and rainy weather during late May 1996 caused widespread mortality among Cliff Swallows (Hirundo pyrrhonota) in southwestern Nebraska. Thousands of birds died, and some local populations were reduced by at least half. I am trying to determine the geographic scope of the mortality event. I am also interested in determining how often kills like this occur. If you are aware of mortality among any hirundinids during spring 1996 in the central U.S. or ~ave recollections or records of other major Cliff Swallow die-offs ln any past years, please send details to me at the above address.
