Respiration should be measured by observation only and not by captive methods. Time the rise and fall of the breast region. Keep your distance and minimize noise to ensure accurate observation of the bird’s regular respiration.
Palatability may be tested by offering a range of foods simultaneously and observing bird’s preferences or by comparing volumes of various feeds eaten. Timing the period taken for birds to investigate and begin consuming newly introduced feed types would be appropriate. High sugar feeds or other unsuitable feed types should not be given, nor should the bird be deprived of its regular diet. Ensure that students are aware that foods that are suitable for humans may NOT be appropriate for birds. Chocolate, coffee and avocado are poisonous to birds.
