I estimate 83k coyotes in north american urban areas. (Extrapolating from 2014 estimate that 2,000 coyotes lived in the greater Chicago metropolitan area.)
Cats are 20-40% of urban coyote diets. Wild ass guess that a 40lb coyote needs to eat about 5lbs per week (based on recommended food allowance for captive coyote). For yearly total of 260lbs. Average cat weighs 10lbs? So each coyote eats 5.2 - 10.4 cats per year.
So let's say coyotes eat 83k * 5.2 = 431,600 cats per year.
A comment above says a domestic cat eats ~38 birds per year.
So urban coyotes save 16,400,800 birds per year.
(Too little is known about wild coyotes and cats for me to even guesstimate.)

So, to answer your question, I'm sure.
