Kitchen Scraps You Shouldn't Add To Your Bird Feeder
By TIM BUTTERS
Fruit Seeds and Pits
The seeds and pits of many fruits contain a small amount of cyanide. While the amount present may not be enough to harm humans, birds are not as lucky.
Like dogs, birds are unable to stomach chocolate because its theobromine content is pure poison to their palettes. Symptoms include vomiting, fits, and heart attacks.
While you might not add a clove of garlic or a piece of onion to your bird feeder, the problem lies with the abundance of kitchen scraps that contain these foods.
Garlic contains allicin, which can wreak havoc on a bird's system. Onions have a high sulfur content, which can aggravate a bird's digestive system and damage internal organs.
