Why is straw not used for raptor bedding?

• A. It harbors fungus leading to aspergillosis
• B. It is cheaper
• C. It dries quickly
• D. Raptors dislike it

Answer: (A)

When choosing bedding for raptors, the health risk from mold and dust is a major concern because these birds are especially vulnerable to respiratory infections. Straw can stay damp and break down, creating an environment that promotes mold growth. Inhaled mold spores, particularly Aspergillus, can lead to aspergillosis, a serious and often life-threatening fungal infection of the lungs and air sacs. Because of this, straw is avoided as bedding. Instead, drier, absorbent, low-dust substrates like paper-based bedding or clean wood shavings are preferred to minimize mold exposure and protect respiratory health. Raptors don’t inherently dislike straw; the issue is the higher risk of mold and resulting disease.
