I have a cockatiel which is about 10-12 years old. he is very healthy and in
good spirits.
Question; How cold can the temperature drop to in the house before it gets
too cold for the bird?

I noticed that common birds like blue jays, cardinals and mourning
doves, have started to lose their feathers on their back, neck, and
head. They look very scruffy. Is this natural, or something that I
should be concerned about? This is in Franklin Park, NJ.
