or accept that I would lose some birds. They will go for the smaller birds first,

I have lost some this season. But it is acceptable considering the size of our Y.B. population. When free ranging, it is a risk to allow a livestock that is so low on the food chain to be exposed to predators that don't have the luxury of a McDonald's or Burger King as an alternative means of a food source
. If they don't find a food source, they won't survive.
I try not going to get worked up if a couple yard birds get taking away by the sky birds.
I can hatch more!
But I can't hatch them while I'm in Prison.
Most of the scores of yard birds I have that are total f-range flock under trees, scratching and pecking, out of view of the raptors. it is almost always the ones that wonder away from the flock out to the open where they become in the cross hairs.
If losing birds is an issue to anyone, Cover a run with nursery netting such as what you will find covering the garden centers at local retailers. Even a giant tarp.
It just needs to obstruct the view from the sky and the hawks circle down away from your invitation.
What ever material we choose to use will be pricey. But far less than the money spent digging our way out of a hole Uncle S. puts us in.

Hawks come and go.. soon will be gone. Hopefully a larger time span between the next arrivals.
