Dissecting Owl Pellets; finding out “hooo” the owl ate

July 14, 2014 sarah Uncategorized

In schools, dissecting owl pellets is conducted as being a science classroom activity typically to learn about life science. It’s advocated to use sterilized owl pellets, from reliable suppliers, for dissection.

In addition to the owl pellets, tools and materials which will be needed for an owl pellet lab include disposable plastic or latex gloves, magnification glass, tweezers, needles, toothpicks, probe sticks, work tray or paper plate, disposable cups, discarded old soft toothbrush, paper towels, plastic spoon, water or peroxide (optional), tub of water-diluted bleach (optional), owl pellet bone identification chart (preferably one which has skeletal charts of common owl prey), white glue, and clean paper.

Of course, it is very important consider many critical points related to the topic of owl pellet dissection. Unfortunately, we can’t cover all of those issues in this short space. We can, however, recommend this information on owl pellets. That resource discusses several important points that aren’t covered here.

Bearing in mind that owl pellets are regurgitated matters which were once inside an owl, remember to wear disposable plastic or latex gloves all the time while implementing the owl pellets and it is contents. After unwrapping the pellet, observe and compose the pellet’s dimensions, structure, and check for any protruding such things as, fur, feathers, or bones. It will also be of assistance to draw or trace the pellet in writing.

For the reason that pellets happen to be dehydrated from the heat-sterilization process, you need to soak it in water for five to ten minutes or perhaps in hydrogen peroxide for five, by using a disposable cup, to restore softer and simpler to dissect. Using a disposable spoon, retrieve the soaked pellet and carefully install it in some recoverable format towels on your 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 locate any small skulls, teeth, vertebrae, and limb bones. Clean the skeletal parts you discover with water and a soft toothbrush. Discussing the bone identification chart, organize the bones into groups and subgroups based on similar characteristics and identify the skeletal structures and kind of animals you see.

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 may also reconstruct the skeleton(s) before gluing the bones in position.

Here is the typical process when dissecting owl pellets.
