I haven't checked this thread for a while but there have been some great posts of late.
Siva - love your image of that, from a N American perspective, exotic bird. About the monopod I use mine all the time with my 400mm. Seems to work for me.
garyk - Great shots. What species was image #3?
Marc - I've seen that Kildeer before but it always blows me away.
Jan - Your wolf shot is amongst the best I ever seen of its kind. That 600mm is an awesome lens in your hands.
Managed an image of a female Red Wing Blackbird today with the old M 400/5.6.
