parrots - They're not great talkers like the African Grey or Timneh, but can learn a reasonable vocabulary, depending on the individual bird and the owner's willingness to spend time training. Loudness The Poicephalus aren't noted screamers or otherwise loud or noisy. Most of their sounds are low key whistles, chirps, squeaks, and assorted chattering. Cockatiels are often more noisy (and more obnoxiously so) than Senegals, Meyers, or Jardines. Pricing
