It got a bit late in the season, but I finally got the foam blocks into the space between the eaves and the walls of the gazebo. Without them in place, the birds fly up under the eaves and into the gazebo. They have trouble getting out again, sometimes, and in the middle of winter or during storms, they can’t get out and find something to eat. There are cotoneasters in our yard, and one of the shrubs, the larger one, is mostly out of the prevailing wind during winter storms. They’re better off there, because when the weather is really bad, and there’s a couple feet of snow drifts a couple feet high, neither of us get out there. We wait for better weather before shoveling a path.
