Bees have been domesticated for over 1000 years. There is no need to trap wild ones.

Or there’s a lost budgie flying around the neighborhood. They do sometimes escape.

A surprising number of lost or found budgies are posted on my local Facebook lost pet group. Maybe it’s from one of those.

The roof in the picture isn’t just gravel, it’s got fist size rocks in it as well. Gravel alone I could understand.

Not in this part of the world though.

You would think the tar would ooze downward on very hot days. (Yes, we get them here.)

They probably could use shingles, there are plenty of surrounding houses with about the same pitch that do.

This is not a flat roof though, it’s sloped.

I wonder how they get them to stay in place. It’s not a steep slope, but it’s definitely not a flat roof. So far I have resisted the urge to ring the doorbell and ask about the roof.

This is in central Saskatchewan. Presumably those southwest roofs are flat - this isn’t.
