After a period of time, the degreasing solution may become saturated with oils and fats. It is essential to change the solution regularly, replacing it with fresh, clean solution to maximize degreasing effectiveness. The frequency at which the solution should be changed will depend on the condition of the bird and the amount of grease present.

Soaking Duration

The duration of time required for the degreasing process will depend on the size and condition of the bird skeleton. Smaller, less greasy skeletons may require only a few days of soaking, while larger and more greasy skeletons may require several weeks. Regularly inspect the skeleton and change the solution until the bones appear clean and grease-free.

Cleaning the Skeleton

Once the skeleton has been effectively degreased, it is crucial to clean it thoroughly before moving on to the drying process. Gently rinse the bones under running water, using a soft brush or toothbrush to remove any remaining debris or residual degreasing solution. Ensure that all bones are properly cleaned and free from any greasy residue.

Drying the Skeleton

Air Drying

One of the common methods for drying a bird skeleton is air drying. Select a well-ventilated area, free from dust and humidity, and carefully lay out the cleaned skeleton. Allow the skeleton to naturally air dry, ensuring that it is not exposed to direct sunlight, which can cause discoloration or bone damage. This process may take several weeks or even months, depending on the moisture content and size of the skeleton.

Using a Dehydrator

For a quicker and more controlled drying process, a dehydrator can be used. Place the cleaned skeleton on a tray within the dehydrator, ensuring that the bones are properly spaced for optimal airflow. Set the dehydrator to a low temperature, around 90-100°F (32-38°C), and let it run for several hours or days, periodically checking the bones for dryness. This method can significantly reduce the overall drying time compared to air drying alone.

Monitoring the Drying Process

Regardless of the drying method chosen, it is essential to monitor the process regularly. Check the bones periodically for any signs of mold, moisture, or discoloration. If any concerns arise, adjust the drying conditions or consult with an expert to ensure the preservation of the skeleton is successful.

Repairing and Reinforcing the Skeleton

Mending Broken Bones

During the skeleton preparation process, it is not uncommon to encounter bones that are broken or damaged.

Apply a small amount of glue to the fractured area and gently hold the pieces together until the glue sets. Exercise caution not to apply excessive pressure that could cause further damage to the delicate bones.

Strengthening Fragile Bones

In some cases, bird skeletons may have naturally fragile or delicate bones that require reinforcement. One method is to carefully apply a thin layer of clear nail polish or a bone adhesive to strengthen and protect these bones. Allow the adhesive to dry completely before proceeding with further preservation steps.

Bleaching the Skeleton

Choosing a Bleaching Agent

To achieve a clean and uniform appearance, bleaching the bird skeleton may be necessary. It is crucial to select a suitable bleaching agent that is safe for both the bones and the environment. Hydrogen peroxide, at a concentration of 3-6%, is commonly used for bleaching bones. Avoid using chlorine-based bleaches, as they can weaken the bones and cause discoloration.

Preparing the Bleaching Solution

Dilute the chosen bleaching agent, following the manufacturer’s instructions and safety precautions. Prepare a solution in a container large enough to fully submerge the skeleton. Take care to mix the solution in a well-ventilated area and wear protective gloves and goggles to prevent any potential skin or eye irritation.
