Can you place the cockatiel cage near a sealed window?

It is very healthy for your Cockatiel to be near a window by nice natural sunlight but they cannot be by a window during winter time or very cold days unless you have wind and cold resistant Windows. If an animal does get too cold they can die just of that but if it is in the summer time right away I say yes that it is very healthy for it.

Just make sure it is not too cold for you Cockatiel.
