Relationship between the Number of Captured Crows and Changes in Rainfall

Abstract

Climate conditions may influence the behavior and ecology of crows. The relationship between the number of crows culled per year and rainfall and temperature during the snowmelt season and apple production was examined for a seven-tear period from 2012 to 2018. The amount of precipitation during the snowmelt season was correlated positively with the number of crows culled by city crow officers, while temperatures during snowmelt season and apple production were not. Potential reasons as to why the number of crows culled was higher in the years with heavy rainfall during the snowmelt season are discussed.
