The lowest-pitched sounds humans can generally hear have a frequency of roughly 20 hz. what is the approximate wavelength of these sound waves if their wave speed is 340 m/s?

Successfully providing nutritionally sound diets comes with patience and persistence. It may take many weeks, even months, of offering new foods before your bird will accept them. Some birds like foods warm and some prefer cooked vegetables to raw. you will discover your bird's particular preferences.

Remember to give your bird time to adjust to a new diet. Offer seeds (only at mealtime) along with other foods until you are confident that your bird is consuming enough of the new foods to maintain itself. Birds are more responsive to diet changes when they are fed outside of the cage (on top of the cage is fine). Remove any food not consumed within one hour. you may offer an occasional snack between mealtimes, but make sure the snack is nutritious.

The final ingredient to a healthy diet is fresh water. You can add a multivitamin to the water until your bird is getting enough vitamins from fruits and vegetables. Most vitamin supplements have a dextrose or sugar base. The sugar base encourages bacteria to multiply in the water; therefore, you must change water twice a day. A better alternative is to sprinkle powdered vitamins (several brands are available at your local pet shop) such as SuperPreen on your bird's soft foods.
