alaskan bowl horned moose and bowl nester

My entry for this months contest

The Alaskan bowl horned moose and the bowl nester have evolved to live with each other.
The antlers of the moose are specifically evolved to house the nests of bowl nesters.
The bowl nesters keep look out from their perch and warn the moose (which has awful eyesight) about predators,when the moose feels the birds fly of all at the same time it means there's danger.
In return the moose provides insects(which swarm around its beard) and protection.
Male bowl horned moose only fight for females when bowl nesters are not nesting
