Blue tits have been in and out of my nestbox since February, almost on a daily basis, and are looking like they're sizing the place up.
Since last week they've been putting in the odd bit of nesting material, but are then removing it the same day.
Anyone got an answer of what they're doing?
The blue tits are occasionally checking out the other box - they did so this morning.
No nest building yet.
Beauty is in the eye of the beholder.
