I believe this is a Migrant Hawker Dragonfly and I can tell you that Dragonflies are very challenging subjects to photograph on the wing as they flit around, the light was not great and light quality is such a important factor contributing to good photography.
I was at the reserve today in the hope of connecting with the Hobby's but sadly they were not very active so to while away the time I decided to focus on their prey.
I plan to take these on as a bit of a project to improve on this image although it is getting late in the season., but certainly next year, as Dragonflies nicely fill the gap between summer and winter bird migrants.
I guess no matter how quiet things seem to be there is always a new opportunity to pursue, you learn every time you go out, that's the lovely thing about wildlife photography ....... a regular and very friendly dog walker and his good lady wife on the reserve shouted across in a very jocular manner ..... '' haven 't you got a home to go to '' ......... I understand the sentiment and it made me smile ..... but observation is key to success otherwise you just go for a walk and see nothing.
