Hi i would recommend a 25mm hole for a blue-tit, in regards to cleaning the nest box all you'll have to do is unscrew the front of the nest box off and clean the nest box out 1-2 times a year.

Or you can buy a standard size 32mm hole in the Alpine nest box and buy our nest box cover plate set which then enables you to have 3 different holes in the nest box for the price of 1 alpine nest box saves you buying a nest box with different hole sizes in. 

Cover plate set

Hope this helps.

Thanks Chris 

Hi Tim,

We use a water based wood preserve on all our products, which gives it that nice golden brown colour, we use a company called Protek in the UK, we had a special mixed made up for us about 10 years ago and have used it since, if you check out there website you'll find lots a different finishes.  

Protek

ps... I haven't used sioox before no sorry.

Thanks Chris 

Hi,

Our alpine nest box isnt quite high enough to fit the camera inside, but we can offer you a camera nest box suitable for the camera if you ring us up to place the order.

Thanks Chris
