The birds that survive must be very prolific, because the article says that house cats devour between one and four billion birds per annum. That's greater than the population of birds that come here, according to my math, but that's what it says.
I had a dozen scissor-tailed flycatchers lighting on the electric wires here for 10 years, then this year, not a single one have I seen. I just can't figure it out, except we had the rainiest year on record in the past 12 months. It rained starting in the summer last year, and we had a month reprieve in August. Now, we have had several days of rain and clouds, but not as much precipitation as they said we'd have. Still, no scissor-tailed flycatchers. They are so absolutely beautiful, It was disappointing not to see them this year. I hope they recuperate and show up next year. I wonder if there was a virus or something that took them away. They stay well away from cats, from what I've observed, and I only have one cat. Recently I've let her stay in the house, even if she is a royal pain in the butt by her zeroing in on my crochet thread. Grrrr! What a pill Miss Piccolo is. Meow.
I think Ms. Piccolo may have had a run-in with a hawk when she was out and about around 6 months ago. For some reason, she was putting up such a meowl-fest, I started leaving her in the house, in a large bathroom space so she will leave my yarns, threads, and fabrics alone. She leaves her toys alone when she has yarn to pounce on and turn a ball into a tattered mass of fly-away money.

Well, really, if I banned the cat, the mice would play. And this house has been scorpion-free since I brought home this cute li'l innocent kitten a couple of years ago. If you've ever stepped on an adolescent-stage scorpion, you will know what undying pain is for a few days. Texas cats seem to understand how to play "I win" with scorpions.
Three billion birds, doggone it. I'll have to start leaving more food around. My husband used to help me with stuff like that when he was living. He loved the birds, too, and helped with the birdbath occasionally.
