Unusual visitor

Had a visit from this guy this morning. He/she came with a mate that was that was smaller and had a lot less colour on the chest area. I was absolutely shocked when he popped by for a quick nibble as I have never seen such a beautiful bird in our garden before. I honestly have no clue on what this bird is but I am delighted that he hung around a bit for me to get a few snaps. Does anyone have an idea on what type of bird this is?
