@de22920b did you know that many birds are opportunistic fruit-a-vores? I had no idea! I thought it was mostly just robins. It's a fun thing to look up.

Also, hummingbirds eat insects for protein and primarily survive off that and similar during winter. Not just nectar. Cool!

(I'm helping!) 

 @d12926de We have three bird houses and one bat house and they remain vacant. Given that you made a video game about birds do you have any suggestions?
