Abstract

Tolerance of conspecifics was observed in 11 pairs of short-tailed shrews (Blarina brevicauda) during a 2-year study of the behavior of these insectivores in simulated natural conditions. Shrews introduced simultaneously to these conditions tolerated each other for less than 4 months before one member of the pair was killed. Shrews introduced to cages containing a previously established shrew were swiftly killed. Blarina should be considered solitary and territorial.
