Shades of Blue

One of the things we enjoy about watching our bird feeder is seeing birds we’ve never seen before.  We’ve had several unknown flying visitors this spring.

There are several of these bright blue birds coming to the feeder now. 

They are small… not much bigger than a wren.  And they aren’t in my book of “eastern” birds. 

Then the other day a bird smacked into the large window on the deck.  Himself went out and brought her/him to recover.

She/he was a beautiful shade of teal.  After admiring her for a while, we let her go.

Does anyone know what kind of bird these are?  Is this a male and female or two different birds?
