How Much Should My Birds Weigh?
Healthy adult cockatiels usually weigh 78 to 125 grams. Birds should always be weighed in grams, which is a metric measurement. (There are approximately 28 grams in an ounce.) It is important that a bird is weighed on an accurate gram scale. Electronic scales are available for purchase from bird-supply companies and office-supply retailers. These can be modified by installing a lightweight perch to facilitate weighing birds.
