Answer: Birds, especially quail, like the seeds from spent flowers, insects, and any new sprouts poking out of the ground. The only sure way of keeping birds out is to remove the things that attract them - cut off spent flowers before they form seed heads, and keep weeds pulled. You can put a thick layer of mulch over the soil to keep seeds from sprouting, and to hide the insect activity from hungry birds. Or, you can place a barrier between the critters and the flower bed by draping bird netting over the tops of the flowers. Once the quail figure out there's nothing in the bed that they can access, they're not so likely to visit as often.
