"Someone suggested that city coyotes do not howl but that doesn't make sense. What do you think?"

I think you probably go to bed early!

I remember south Texas coyotes howling just as it got dark. I'd hear them if they howled then.
People who are up very early like 4:30am say they see them and Security Guards who are patrolling all night do too. There are signs all over this area, offering rewards for cats and small dogs. We are close to Buffalo Bayou and if they were howling in the night my Jack Russel Terriers would let me know about it. If it ever gets cool here we will be sleeping with the windows open and we should hear them.
