Nest boxes have proved reliable. And for many reasons.

As CrocDoc mentioned, many species including Savs, make fairly long burrows for the safety of the nest, then bury them deeply and hide all signs of the nest.

This must be very important to them.


Also if you provide decent heat options, its hard to keep the nest box cool enough, if its above substrate level.

ALso, Many monitors just do not recognise a box as anything usable. They do even try to nest in them.

So for the most part, above substrate level nesting has not worked to well, and when it has worked its been very inconsistant. But there have been a few exceptions. Sadly, not with Savs.

I have to wonder, how did you come up with those ideas of yours?
