bird feeding and watching

I'm in Brandon Florida and have 3 feeders.We of course have dozens of cardinals,titmouse,wrens,bluejays, turtle doves and several different woodpeckers. We have a bird we cannot identify. It's light grey with a light yellow breast. Does anyone know what it is?

I bought a National Geographic bird guide and havent found it in there yet, havent researched thoroughly yet though. It is about the same size as a cardinal, it is very light grey and the breast is very light yellow. It has a short pointed beak like a small woodpecker. We had large dead limb on one of our old oak trees and they would go in and out of a "hollow" in it. The limb fell off 2 weeks ago, the birds are still around. We have several pairs of cardinals, always fun to watch. Last week I noticed a male feedeing a female.

Check out Great Crested Flycatcher, and see if that matches.
