This was my pandemic hobby as well. After I consistently offered peanuts for a couple weeks, a crow couple would visit my balcony daily. In the springtime, they had a fledgling, and the whole family would come over, which was adorable. I trained them to open containers, and then put out puzzles of increasing difficulty for them.

Here's a video of one of them solving a couple of puzzles: https://www.youtube.com/watch?v=0x0PwKHvW10

And here's one of them taking a bath, just because it's so cute: https://www.youtube.com/watch?v=-AgAIh43OUs

It's a highly entertaining hobby, and I'm excited to continue putting out more interesting and complex objects for them to interact with!
