Bye-Bye baby Birds

Well.....the baby birds have left their nest. I just knew that it would happen when I wasn't home. Tuesday , after getting together with friends, I came home to find the nest empty. I looked everywhere for those birds, thinking it wasn't time for them to fly yet, I came in and called Chad in a panic to tell him, seeing as one had gone missing, praying that he/she spread her wings and flew away, and after hanging up the phone decided to look one more time. I could not believe what I saw. Both birds were sitting on the deck underneath the tree that we put out there to shade them. I put them both back in the nest...with trash bags of course...and then watched to make sure the Mom and Dad came back. Well yesterday before I left to go out, knowing I was going to be gone for 6 hours, I checked on them and as I looked out the window one was jumping out of the nest, as I opened the door she jumped back in the nest...needless to say when I returned back home they were both gone:( I know that it was time to spread their little wings and fly but I will miss them. I know they are glad that I was gone that day because they would have been pretty frustrated me putting them back in their nest all day:) maybe we will get some more next year. I have been told that they always come back to the place they built before.
