Quick one-handed grab with my phone. Could a crow fit through this hole. I think so!

We bought some screen patches and upon further study in the screen room, which we just about never used realized that ALL the screens need to be replaces - holes and rips all over the place from bird and squirrel visits. This winter I will be feeding the birds out front where there will be no screens to damage. It'll mean a different photographic lifestyle, but enough damage is enough.
