It was in the grass at the side of a field - as far as I know, it was a cock pheasant. I don't think Jarvis can tell the difference
My dogs are kept away from places that have nesting birds at this time of the year or are kept on a lead, hen pheasants have a hard job raising their young and are not good mothers, once spooked there is a high chance they wont come back to their nest or young.
There are also many other ground nesting birds out there too doing the same.
