A month ago, I took a picture of a nest some birds had built in my grill:
I removed the nest (no eggs were in it, thankfully) and since then have removed parts of a new nest several times. Before using my grill tonight, there was yet more work done on a nest. I removed the materials, and within 30 min of turning the grill off, they were at it again:
I'm worried that one day, I'll open the grill and find a completed nest with eggs. What then? They can't live there all summer! They will also be competing with wasps for use of my grill as a home!
