European Turtle Dove adult

We saw a Dove sitting on a fence ahead. Expectations were that it would be a Collared Dove which are plentiful at Riverside. However, when it flew, its tail pattern immediately showed it to be a Turtle Dove, a bird which I have not photographed well previously. Although it kept calling for the next hour, it was in a restricted area of the park and hidden. Eventually, I found a position on the track which gave me a narrow view through a small gap in the foliage to the bird beyond.
