Congratulations on capturing a close photo of a Belted Kingfisher. It is a species that I have found to be very wary of people and often departing the scene when I approach from even 200 meters away, a distance that would render me no threat at all. I don’t know whether you have a 500mm or a 600mm lens, but either way, that’s the kind of power you need to capture these birds. You are still losing detail because of the overwhelming contrast in your photos. The Humber trail must be Hawk haven considering the number of times you seem to spot them. I saw a couple of Cooper’s flying directly down the street as if it were a designated raceway. Just blowing off some steam, I guess.
I tried to capture additional detail on one of your pictures but the noise was too great to retrieve much buried within the contrast.
