Only recorded from 8 tetrads. Much smaller than the common shrew with a proportionately longer tail. They are essentially solitary and, like the common shrew, are aggressive towards each other.
Pygmy shrews in lowland habitats are less abundant that common shrews.
The continued loss of semi-natural habitats and use of agricultural chemicals has probably led to a population decrease. Like the common shrew, the pygmy shrew is found in owl pellets, is a victim caught in discarded bottles and drink cans and is often killed by domestic cats.
