A canary ? Its either on its perch or dead. Binary signal output. Use a microswitch
You will need a timing delay to detect if this is a dead bird resting on the switch or a live one perching on it.


No, no, I was going to ut the switch in the arc that its head swings in as it falls off the perch.

That's assuming it really is dead, and not just resting...
