Guess who won? I know hornets are pretty efficient predators of all sorts of insects (last week I saw one killing a honey bee), but never thought that they were able to take on such large things as migrant hawkers! I saw this yesterday morning - the hornet was in the process of bringing down the dragonfly in a hedge next to the trail at about 08.00. Perhaps it was able to catch the dragonfly before it had properly warmed up. Once on the floor the hornet methodically chewed off its head and part of the thorax and flew off back to its colony.
Also yesterday - female peregrine back on its usual perch at the hanger and a few pintail amongst lots of teal, mallard and wigeon on the north brooks. Marsh harrier seen hunting the south brooks during the morning. Raven(s) seen regularly over the site in the last week.
