From Rosemary Royle: Yesterday evening we watched a Willow Warbler regularly entering a Great tit nest with small items of food and feeding the Great Tit young. The Willow Warber nest is very close by and we can only think it is getting distracted by the loud begging calls of the Great Tits. We shall wait to see how things develop!
