Young Birds on Site

Out of 4 nest boxes at 30 Birch Wood only one remains, we have had 2 Great Tit nesting and raising young and all have fledge the nest, there is one Blue Tit nest box still  remaining and are still feeding up until yesterday. The Adults look as if there having a hard time of it by looking at the state of the feathers. The young are popping their heads out so it wont be long now before they go.B72A4885 B72A4888 B72A4893
