Gloucester, Ontario

I was at one of our favourite birding locations (near the Ottawa International Airport) looking for Bobolinks; Bluebirds; and Swallows for which the site is very well known. Between bird shots I was photographing aircraft; switching between A-Priority for jets; and S-Priority for prop jobs. I heard a different sound and got ready; and was surprised (not to mention pleased) when I saw the two Snowbirds clear the trees that had been blocking my line-of-sight.
