nestbox cam question pls help

[natureshooter]

Just setting up my nestbox and cam for the bluetits next year,i want to focus the cam to get best results but i need to know a question.

How deep generally is a bluetits nest?

So i can focus on something inside the box at roughly the same height as the chicks will be.


Thanks Gary

How deep and wide is your nest box?

Hello,
I cleaned out my box a couple of weeks ago and the lining material was about 4 cms deep.
I imagine that you need to focus another 5cms up from that, so 9 cms from the bottom of the bird box.

We still have the nest from one of our camera boxes (in an ice cream box in the shed). The total depth of the nest material varies between 5 and 6cm, with about 1.5cm between the bottom of the nest cup and the base of the box.
