For the #Age-of-Avians
The Marshpecker is a species of woodpecker that evolved for life in marshes and is roughly the size of the Ivory Billed Woodpecker. Marshpeackers have formed a symbiotic relationship with beavers by feeding on any troublesome wood eating insects that would be harmful to beaver dams. This benefits both the beaver and the marshpecker: The beaver has its dam free of wood eating pests and the marshpecker gets a tasty meal. The beaver may even the marshpecker eat the parasites that might be in the beaver's fur.
Another example of this symbiotic relationship is that when a predator, the marshpecker will emit a loud squawk to alert the beavers. In return, the marshpecker may be allowed to take shelter in the dam.
Comments would be appreciated. Thank you!
