Nicely made stainless steel plate. No sharp edges

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.

fitted one last year and Biue tits used it successfully and reared a brood.
Very effective deterring bigger birds.And another bonus,the Blue tits never complained about any sharp edges !!

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.

No nesting in any of my 3 garden boxes this year. These 25mm plates are way to small and almost impossible to enlarge as they are constructed from stainless steel. Should be 28mm for blue tits as they were clearly finding it very difficult to pop in and out of this very small plate.

RSPB response - 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. These are made from stainless steel to minimise the risk of predation to a nest box, softer materials would not be as effective in achieving this. There are many factors that determine if a nest box is used or not, further advice can be found online at http://www.rspb.org.uk/advice/helpingbirds/nestboxes/smallbirds/siting.aspx.

Very simple and easy to fit to a next box. I also found the metal to be very sharp at the edge so sanded it with standard wood sandpaper, which worked well.

If you have a lot of sparrows then this is a really good idea. I've seen first-hand what happens when sparrows 'displace' blue tits and it's very sad when the whole brood is slaughtered. I didn't think sparrows could do that but now I've seen it with my own eyes. You could of course make your own, or just buy this to save you time.

blue tit are finding 25mm hole to small,so i need to anlarge it. Also you will need to smooth inner egde as it is quite sharpe .
