Shrews are small mammals that often occur in sympatry with other species of shrews. This suggests some form of resource partitioning is occurring. I examined eight habitats in Jackson County, Alabama, and detected evidence of habitat partitioning by shrews in pine forests, mixed forests with liana undergrowth, and deciduous riparian zones. Also, I discovered that I was 11 times more likely to capture a shrew on a night with rainfall than on a night with clear skies. Habitat segregation and increased activity on rainy nights should both be considered when researchers attempt to capture shrews in the field.
