The snow geese in our back yard in the sky can't see them but can hear them!

We were in the house Sunday night 3/14 and we could here this noise and Michael goes what is that? I go I don't know? He goes It's the white snow geese! They are flying to Canada. It was so cool to hear them! He wouldn't talk so that's why I am asking him! He didn't want to be on the video camera lol This is what we get to hear in our backyard at night! It's so peaceful hearing all the birds!!! we are going to be seeing a lot of them soon with all the bird houses we got :-) I can't wait!!! I love watching birds :-)
