If a squirrel bites off a hawk's toe, what is the likely outcome?

The most likely outcome if a squirrel bites off a hawk's toe is that the toe will probably not grow back. In most bird species, including raptors like hawks, if a toe is lost due to injury, it typically does not regenerate. Birds do not have the ability to regenerate limbs or toes like some reptiles can; thus, once the toe is lost, it is permanently gone.

While there may be instances where certain birds can develop some degree of healing at the site of the injury, complete regeneration of the lost structure is not part of their biological capabilities. The hawk will adapt to function without that toe; however, the loss will impact its hunting and perching abilities. The healing process may lead to some adjustments, but the original toe will not reappear. Therefore, while adaptation is possible, the biological fact remains that the toe itself is unlikely to grow back.
