Cockatiels, like many parrots, hail from exotic tropical places.
This makes Houston (aka the warmest, most humid city in America) a perfect alternate home if you are small with downy feathers and a hooked beak.
However, occasionally even Houston has its less humid, less warm moments.
When these occur, you can use your signature “fluffy feather alert system” to let the large featherless being know it is time to turn. up. the. heat. already.
