Too small?

The female blue tit finds it really difficult to get in through the25mm hole, anything up to half an hour of frantic attempts until she finally forces her way in, lands beak first headlong amongst the eggs disturbing them, and starts brooding again. All the wisdom is 25mm is fine for a blue tit, but maybe the females are a bit fatter when egg-laying?

Thanks for your review. The RSPB recommends hole size of 25 mm for blue tits. Blue tits will feel safer and more comfortable in a hole that is around 25 mm, as a hole that is a slight squeeze for them ensures that nothing larger can enter the nest.

Fits the purpose

Bought this to reduce the apex bird box entry down to blue tit size and to prevent predators enlarging the whole. With reference to previous reviews I would agree that the inner side of the hole is rough but wouldn't class it as sharp, I dragged my finger fairly firmly against this and did no damage so wouldn't expect any issue for a lightweight bird with feathers for protection. Will definitely buy more when purchasing more boxes. Only negative I would add would be that if you bought this as an after thought the price for posting would be a bit much, but fine if bought with the nest box. By Ian, on 2 Mar 2015
