Kingbird or Flycatcher

I had two different new birds today. They came in pairs. This is the best shot I could get and the other pair I only got a shot from the back but they were a blue color similiar to some of the Tanagers.
Maybe tomorrow they will come back. Anyone that can identify let me know what it is.
Hope everyone is having a good week end what beautiful weather we are having here in Florida.
Thank you for your comments.
