Unexpected fruit tree

So, there's a tree in our backyard. I don't remember noticing it when we first looked at the house. Suddenly it's covered in what appear to be apricots.

The tree next to it is sporting one or two small green fruit that look rather like apples or Asian pears.

I was plenty ecstatic about just the lemon tree and the grapefruit tree that I already knew about. Surprise fruit trees are very exciting.
