Dissecting Owl Pellets; finding out “hooo” the owl ate
In schools, dissecting owl pellets is conducted like a science classroom activity typically to find out about life science. It is suggested to use sterilized owl pellets, purchased from reliable suppliers, for dissection.
Besides the owl pellets, tools and materials which will be necessary for an owl pellet lab include disposable plastic or latex gloves, magnification device ., tweezers, needles, toothpicks, probe sticks, work tray or paper plate, disposable cups, discarded old soft toothbrush, paper towels, plastic spoon, water or hydrogen peroxide (optional), tub of water-diluted bleach (optional), owl pellet bone identification chart (preferably the one which has skeletal charts of common owl prey), white glue, and clean paper.
Of course, it is important to consider many critical points related to the subject of owl pellet dissection. Unfortunately, we cannot cover all those issues in this only a little space. You can, however, recommend this article on owl pellets. That resource covers several important points that aren’t covered here.
Bearing in mind that owl pellets are regurgitated matters which were once inside an owl, make sure to wear disposable plastic or latex gloves all the time while taking care of the owl pellets as well as contents. After unwrapping the pellet, observe and put in writing the pellet’s dimensions, structure, and be aware of any protruding things like, fur, feathers, or bones. It will also be helpful to draw or trace the pellet on paper.
Because the pellets are dehydrated from your heat-sterilization process, you need to soak it in water for a few minutes or perhaps in hydrogen peroxide for five, using a disposable cup, to make it softer and simpler to dissect. With a disposable spoon, retrieve the soaked pellet and carefully stick it on paper towels on your own work tray or paper plate.
Using tweezers, toothpicks, needles, or grab sticks, gently tease the fur or feathers away from the embedded bones. Search carefully to discover any small skulls, teeth, vertebrae, and limb bones. Clean the skeletal parts you find with water along with a soft toothbrush. Discussing the bone identification chart, organize the bones into groups and subgroups according to similar characteristics and identify the skeletal structures and form of animals you discover.
Glue the bones to paper or cardstock and label the bones. An optional step is always to soak the bones in water-diluted bleach to whiten them before gluing. Alternatively, you can even reconstruct the skeleton(s) before gluing the bones in place.
This is actually the typical process when dissecting owl pellets.
