I am a very proud owner of a mated pair. I first got my blue male from a rescue where he was in a cage with Gretta. I had Parry for about a month, and even though we bonded rather quickly, he seemed so sad. After doing more research on mated pairs, it came to my attention that these birds mate for life. long and wonderful story short, I went and picked up Pare Pare's mate.
So anyway Gretta is adjusting very well to our family, but I haven't had her long enough to know, why she is sleeping, or staying in her cave so late in the day. This did just start when it started getting dark earlier. I have only had these two a little over a year so just wondering if this is normal?
Welcome to the Forum! I'm not sure about why Gretta wants to go to sleep so early; it could be related to nesting/breeding behaviors. Has she been seen by an avian certified vet recently? It's always a good idea to take a new parrot for a well-bird checkup soon after bringing the bird home.
