I am hopeing that this does not indicate a shortage of food for hawks this year. I have read that mice and other rodents can retard or reabsorb young when the food is scarce. We had a wet period early followed by very dry very hot weather. Many of the weeds have not produced their regular amount of seeds. I can not feed the hawks directly but perhaps I can feed their prey.

I don't think you have a problem. Smaller hawks often chase larger hawks, regardless of the prey base and regardless of whether or not the larger hawks scored a hit. They just don't like them around.

Hawks will also try to pirate food from other hawks. That makes for easy meals.

The shortage of food runs in cycles every few years, that's true! I hope this is not a bad winter for the hawks.
