Bats always garner student interest and Acorn Naturalists offers many educational resources that enhance bat explorations. This section includes bat skull replicas, bat scat replicas, bat fur replicas, bat houses, bat puppets and bat study kits. Acorn Naturalists also offers sophisticated ultrasonic bat detectors for identifying bats as they fly past at night. The Echo Meter bat detector we offer plugs directly into hand held devices (iphones, Androids, ipads) and records bat ecolocation sounds and identifies individual species. These recordings can be downloaded and shared with others. Bat detectors add tremendous excitement and interest to night hikes, camp programs, or citizen scientists monitoring bat populations. The data collected also provides valuable information on which species of bats are present, as well as when they appear and in what numbers they are found.
