Nest Boxes

These nest boxes were in our shed for 3 years!!!
It's a box for a Northern Wren (winterkoning) and a
nestbox for a Short-toed Treecreeper (boomkruiper).

At last we found a spot for them.

Short-toed Treecreeper

Wednesday evening we saw a couple of Short-toed treecreepers (aka Certhia brachydactyla) gather nestmaterial and dissappear under the second tile (from the top) on the left. 

It was obvious they were building a nest.

We were really enthusiastic and then we did something really stupid!

We scared them off trying to make a picture :-(

On thursday and friday we saw them looking for food under all the tiles but no more nest material flights.

Hopefully we will get a second chance.
