Please remember that you can call the city and the animal warden before the cops. Theoretically the cops should not be called for civil disputes which this is. They're there for criminal disputes, and calling the cops for a non criminal issue... Let's just say it's not a good idea. The city will probably inspect, fine, etc. That's what they're trained to do and legally are able to do. They can submit a notice of inspection and just deal with it. The cops? Who knows. In theory they need a warrant from a judge to enter the property. They're not trained to handle it. They can also simply be denied entry to the property.
Catching the birds on your property and sending them to a local shelter might also be an option. That way they would have to pay a fee to get them back, just like a loose dog.
My chickens have gotten out every once in a while but we have a 6' fence. One time a neighbor opened my fence and let them all out (we have padlocks now) and another neighbor called the cops. The cops came in and spent the whole day chasing four leghorns I'd had for 2 days all around the neighborhood, terrorizing them and spooking them permanently. It took 3 hours to find them all again, when the day before they were walking right up to me... They never were quite 'right' ever again and hated humans ever after. So call the city and the animal warden before you call the cops.
Otherwise... I do think this is a situation where contacting an authority might be appropriate. It's not the responsibility of a landowner to fence other peoples animals out, it's the animal keeper responsibility to keep them in unless there's an attractive nuisance.
Motion sprinklers, lights, etc might also work. But they might also be temporary.
