Robin's nests under deck
We have several robin's nests being built on the cross beam under our deck, which is an area we use quite frequently when we're outside. I'm afraid if they build there, we'll keep scaring them away after they've laid the eggs when we're out there working or just enjoying the yard and patio. I've removed the nest building materials once and put plastic bags held down by rocks up there to keep them away. But it's not working. Any suggestions?
