Hello, In my garden, I have a 5m tall conifer tree. As of recently (within the past month), the blue-tits and dunnocks that visit my garden keep flying up to the conifer and going inside for a couple minutes, only to exit and fly away afterwards. I am not familiar with certain behaviours birds show, but I am wondering why they are doing this. Why would this occur? This only really happens at midday and dusk. Any answers would be much appreciated. Thanks
In addition to James' reply about the insects, I'll add that many insects can be active at temps as low a 3.5ºC!
Also, further to James' reply, many trees are in bud and will have been since December, so there could also be some juicy new shoots for the blue tits to nibble at.
