Sweet birds!!
Bye Yauco.
In the early seventies I used to keep a few Strawberry Finches together with a couple of Parakeets in a large flight cage. They got along very well and lined up on their perch in pecking order every night to sleep. The Parakeets tried to sing like Finches!
.
Things got really funny when my neighbor asked me to "bird-sit" their little Canary while they went on vacation.
She warned me that her bird might be needing some time to get used to being in the cage with other birds. Ok. She wasn't gone for more than 10 minutes when the little canary started to sing his little heart out. And so did the silly Parakeets - the next few weeks they were trying to trill like a Canary, more or less successfully.
Unfortunately I heard that I ruined the Canary, he never sang as nice/happy? as he did in the community cage. I think he was actually lonely.
