Woodchuck?

Do Woodchucks have an alarm at the sign of danger.
I don't know if it was a bird that made a loud whistle sound
when I was scouting the entrance of the area, I have seen a path that have made.

A quick sharp whistle and they're gone and their friends in the neighborhood are on the alert or gone too.
