Habitat
The Luzon shrew primarily inhabits montane and lowland forests on Luzon Island in the Philippines, often found in leaf litter, under rocks, or near streams. It prefers moist environments with dense vegetation for cover and foraging. This species avoids open areas and is typically found at elevations up to 2,000 meters.
Diet
The Luzon shrew feeds mainly on insects such as beetles, ants, and earthworms, as well as other small invertebrates. It is an opportunistic hunter, actively foraging at night using its keen sense of smell. Feeding occurs primarily during dusk and dawn when prey is most active.
Behavior
The Luzon shrew is solitary and highly territorial, marking its area with scent and aggressively defending it from intruders. It is nocturnal, spending the day in burrows or under logs and emerging at night to forage. This species exhibits rapid, darting movements and vocalizations like high-pitched squeaks during interactions.
Conservation Status
The Luzon shrew is classified as Data Deficient by the IUCN due to limited data on its population size and trends. Major threats include habitat loss from deforestation and potential impacts from climate change, though its population trend is unknown.
