I read a Reddit question about a cockatiel that munched a tiny bit of this plant commonly known as Split leave Philodendron and her vet said her bird would be fine but don't let it happen again. Her bird was fine but she was still worried. Further reading said that the ill effects from eating this plant are GI related (it's a local irritant to the mouth and GI tract more than an actual "toxin"). If Muffin is eating and pooping normally he will probably be fine too. If you notice any signs of mouth or GI discomfort take Muffin to an avian vet.
This thread, and a pet news clip about a puppy that almost died after swallowing one of his owner's socks, got me wondering if some of our birds that have suddenly gotten very sick and even died had swallowed something dangerous when we weren't looking. Like a piece of a toxic houseplant, something stuck on a shoe and brought inside like a grain of ice melt, a dropped prescription pill, etc. There are so many environmental poisons out there. I wouldn't be surprised if a number of pet birds that are allowed out of their cages (like they should be) succumb to undiagnosed accidental poisonings like this especially those that like to walk around on the floor. It's impossible to keep our floors free of all tiny potentially harmful particles and some birds tend to swallow things. In addition to poisonings, they could get dangerous crop obstructions from swallowing inert things like pebbles, lint, threads and animal or human hair. Even toys in their cages can be chewed into pieces that can cause problems when swallowed.
