It's (late) Tuesday so it's time to learn a little fact!
Mammals can 'taste' heat, like in spicy* food...
***(technically called piquancy while we're at it)
...birds can not.
So what? Well, if you have a problem with squirrels eating your bird food (don't we all?), supposedly just adding some spice (like chili powder) will solve your problem! Voila!
Have you tried this? Did it work?
