This is our garden shed which my Lovey built a year or two ago. I'm still putting up all the nails I need on the inside for hanging up tools and eventually I want to put a little shelf along the back wall for potting stuff.
On the back of the shed I hung an old parakeet nesting box and it has been used several years quite successfully.
So spotting them has been some of our nature studies this summer. I think they're sparrow, of which we have quite a few around here.
