Hovers, garganey, gwe and an unfortunate deer

I had a pleasant day today, I was cutting the trails as the nettles have now started to overhang quite badly. This gave me a good opportunity to get out and about and see what was going on on the reserve.
Sandy wall had a fine Ferdinandea cuprea (my second ever!) also hornet hoverfly yesterday on budlia with a hummingbird hawk moth, which escaped the camera.
Tower Hide held at least 2 garganey, the great white egret, 47 shoveller, 2 wigeon and other common duck species.
 Lackford run held a rather unfortunate immature chinese water deer. there were some odd circumstances surronding its death... essentially it looks like its leg fell off! there is a very clean cut/tear around the leg socket and the leg was just 50cm away from the body, so whatever did it didnt eat any of the flesh it just pulled its leg off and went about its business! I have seen fox, train, car deer kills but this looked quite different, a bit of a mystery, any suggestions welcomed and apologies for the gory pictures!
After moving the deer off the path I had the pleasure of seeing 10-15 willow emerald damselfies, some of which posed reasonably well for their picture to be taken.
