We know that humans prefer certain foods but do animals? An investigation was done with a pair of zebra finches to find out. The zebra finches were tested with a seed mixture bought from a pet shop to see if they preferred to eat certain seeds in the mixture. A sample of the mixture was left in a dish in the bird’s cage for 6 hours. At the end of that time the sample was removed and the seeds were separated into their different types. A sample of the original mixture, called the bulk, that was similar in size to the dish sample was also sorted into the different seed types. please i need your help!
