Nice pic ,yea I have a 400 5.6 and 70 -200 f4 L IS and have a Carolina Wren close to house and think I might can get close enough with the 70 -200 .
I will try both and see . She is just making a nest in a flower bed on window sill . The nest will be hiden but I figure I can wait to see the bird land among the red flowers.
