Not a bird... But, it was supposed to be a bird blip today. The little singer was calling for spring in one of the trees outside my windows. I heard him sing for a while, when to find him and finally decided to change the lens and catch him with my camera. So when I got to the right window, were I spotted him minutes before, he was silent and had moved on. I swear that bird knows when I'm coming with my tele lens!! This has happened before... 
What do you do then, tele lens mounted on camera... well, the roses were there and I tried a different angle.
