Have you considered making a birdbath type thing close to the ground for them to drink out of?

I've thought about this, but didn't want to make my home more attractive than it is. I have a small dog and my neighbors have several pets who would probably be at the losing end of encounters with coyotes.

Your outlook on the human prerogative for mastery of his environment is absolutely fascinating to me.

"Don’t believe the world owes you a living. The world owes you nothing. It was here first." loosely related

Consequently, "You don't owe world anything. Tame it to your whim."

I think it's rather: "The world and you both owe each other things."

The Dust Bowl was among the many times nature called humanity on its hubris.

And suffer the consequences, good or bad. Tame it wisely.

Yeah. It wouldn't keep me from defending (a pet, me, my wife, a kid in the neighborhood) from a coyote attack, but I don't have a reason to make their lives more difficult. Fellow mammals, just getting through life, etc.

And it's my (illusory) hope that they'll eat the occasional gopher while they're in my yard. The gophers compete with me for food. The coyotes don't. Yet.

In a symbiotic relationship who is the host and who is the parasite, your post reminded me of an old story themed "host or parasite" from here https://www.youtube.com/watch?v=F5lLxJWew7E&t=13:30

Do you know how they discovered that it was water that was inside the pipes?

I don't know.

It's possible, as another poster mentioned, that they can hear water flowing through the lines. The surroundings are utterly quiet, and I run the irrigation at night. I can hear turbulence noise in the lines before the water emerges from the local applicators.

On the other hand, coyotes are canids. Their sensory skills are optimized for olfaction. Maybe they can smell the minuscule amount of water vapor that leaks through the push-to-connect couplings. Plus they seem to be pretty smart. It might take only one coyote Einstein to discover "plastic lines here = water" and pass it on to the pack.

They may be able to hear it. Coyotes have crazy good hearing. That is based on 0 scientific evidence though, just a guess.

As a wise person once said, "You might love nature, but nature doesn't give a fuck about you."

They'd gladly "snack on your dog" or your child, given the opportunity.

I’m not sure how much land you’re talking about, but an ah professional friend of mine suggested metal fencing since that’s what has been effective for a lot of growers he knows.

If you’re talking about a casual garden, I’ve got nothing for you other than (maybe) metal lines.

Small property with topography that makes it difficult to fence out critters. Metal lines are the answer.

One night during the drought, I came upon two coyotes killing a cat right in the middle of old Mountain View.

Cats belong inside. For every cat preyed on by a coyote there's 100 birds preyed on by a cat.

Build a water trough.
