Sparrowhawk food


yesterday a female sparrowhawk attempted to catch my budgies through the aviary wire, and spent about an hour in my garden again this morning. My budgies are perfectly safe, no concerns there, but I’m worried about the sparrowhawk herself. I was thinking of leaving some food out for her, as she must be starving, but what can I easily get hold of for her, and leave out? 
Thank you :-)
