The hollies locally are already laden with ripe berries, way before time. Although the greedy wood pigeons usually have their fill, these food larders are eagerly visited by visiting Redwings and Fieldfares. I wonder if the visitors natural know how, will automaticaly adapt. Also over recent years. Our cheeky sparrows have disappeared, also the swallows and martins. I can't remember the last time I saw a song or mistle thrush.
