Finches have similar problems with seeds and plastic. Feeding can be a very frenzied activity. Birds are likely to swallow before they taste. They can t digest plastic. So plastic just builds up in their stomachs taking the place of real food.
Birds slowly starve.
Let s see how easily plastic can become an undesirable meal. The object of this game is to collect as much food as possible in the time allotted. Because of the collection method and the short time allowed, some plastic will be gathered also. In each tray, mix plastic pieces with bird seed or popcorn. Have three children feed at each tray for 30 seconds, using their spoons as beaks.
