In most of the identified prey that I have gathered, it is quite obvious straight away which is diurnal and which is nocturnal, Moorhen, Woodcock, Little Grebe and Water Rail are showing up. These are all weak flying birds that you rarely see moving great distances low or high in the daytime. Additionally I have found at the prime nocturnal site, 3 Redwings stashed together, 2 intact and one partially eaten, these are massive nocturnal movers, I suspect these were also taken at night.
The other day I visited a site in London to bag up prey, and was dived on for my troubles by the resident female, even though it is still over 2 months till egg laying, they are still territorial this early on. Quite a sight to see her coming down at speed at you, great to see, managed to get a couple of out of focus shots of her. She pulled up above my head but the message was quite clear.
