Look at these Love Birds!

These birds were pecking at my window.  They were so cute.  I think they saw themselves because it is reflected glass from the outside.  They were playing there for about 5 minutes.  I was able to get pretty close to them and take a picture from the inside.  Just could not help myself!  Does anyone know what kind of bird these are?  They have that fan type thing at the top of their head.  I figure they are male and female.  I have seen them before about a week ago or so, walking around the grounds.
