Unexpected guest

I've been waiting for weeks to see a baby House Sparrow fledge out of the nest which is outside my back door. (I think I posted a pic of the birdhouse awhile back) well, I opened the door to check on them, and just as I turned around this little one flew right into my kitchen!! Guess I spooked him. After a bit of shooing it to go back outside I realized I was stressing the poor thing more, so I gently picked it up and tried putting it back in it's home, but as I let go he flew away. Strong flier for one so fragile! So I finally got to see a baby bird leave the nest!
