Hi everyone,
i have been trying to figure out if Blueberry, my sisters budgie, is a boy or girl. We have assumed he was male for the past two years, but his cere is clearly the brownish red of a girl. It doesn't sing like the other males we have had, but then again, it is a "slow learner". I really think she is a girl, but my sisters disagree. What do you think?

Thanks,
skylover
