On Thursday, January 6, of this year (1938), I received by mail from Mr. Weir R. Mills, of Pierson, Iowa, the bodies of twelve birds. They were all Lapland Longspurs (Calcarius lapponicus). Later a letter reported that these bodies had been picked up from the streets in the business district of Pierson on Thursday morning. This was the first intimation I had of a rather wide-spread destruction of these birds in northwestern Iowa on the night of January 5-6. It may be well to state at this time that there was a light snow fall on this night, but it amounted to less than a half inch. The effect of the snow on the birds will be discussed later.
