| Little is known about the lifestyle of Merriam's Small-eared Shrew, in spite of its extensive geographic range from southern Mexico through northern Costa Rica. It has been found in broadleaf and evergreen mountain forests and in agricultural areas near forests.
Shrews are notoriously hard to observe in the wild or to trap, and therefore they are hard to study. Pitfall traps, deep, straight-sided cans set into holes in the ground, work best, but digging holes and placing the traps where passing shrews will stumble in requires hard work, dedication, and some luck. Pitfall traps are not normally baited, but they are frequently combined with little drift fences that provide something for shrews and mice to run along and then fall into the bucket.
Head and Body: 65-76 mm; Tail 24-33 mm
