As a proviso please remember this data was compiled by multiple and not necessarily experienced observers and many unidentified items were simply unlogged. But it does serve as an interesting introduction none the less.
So what did we find? Pheasants and partridges have been reported as prey in some locations, and indeed a pheasant was reported brought in here. But it is important to keep perspective in that this represents just over 1% of their observed diet. Extrapolated to an average of 11 prey items per day as quoted by other studies this suggests up to 5 pheasants may have been taken during the entire nesting period. So are the harriers bad for game birds here? We would suggest not - and that they are actually beneficial believe it or not. In the same period 9 rats were observed brought in (extrapolated to 44 during nesting) and as substantial predators of eggs and nestlings the removal of 44 rats would we imagine reduce predation of ground nesting birds like pheasants and partridges.
The real losers were coots and moorhens with a likely 153 chicks taken from the surrounding wetlands, closely followed by 49 rabbits and 34 water voles during the season. The completed chart shows the proportions here:
