Bird ID needed
 

Sorry, didn't get a photo, but had his'n'hers birds that we haven't seen before, he sitting on our bluebird box and she having a good look inside

Each had a quite bright yellow breast and a crest, a bit smaller than an American Robin (so doubt they would get into the box anyway) and rather like a woodpecker's head

They don't feature in Florida's twenty most common birds

For future reference, down load i-naturalist to your phone. Youi can take a picture or two of a bird, animal or plant and request an ID. The software comes back with a few suggestions. There is also a community of people who will help with an ID. It uses your location as well as your picture to ID.
