Pchela and everyone, thank you so much for the information and advice. As for the naming, my mother and her partner just calls him/her Pikoy so I just followed that, not knowing much of the language (I was raised in the UK). With the string tied to its leg, it was only a temporary measure until we got it a cage (which we did). Luckily no harm was done but we will not do that again. Also I did not know this species could talk like us...is that right? I'll have to check up on youtube for this one. I keep trying to teach it to say banana, though it only vaguely says it when it's actually eating one...something like "bawawa" lol. The previous owner actually had a dog who tried to bite the poor thing...but thankfully no severe injury was made. Instead she was placed in a plastic bag when rescuing...so I think he/she had a bad start in life
For the lovebird, I originally put it with the larger parrot's cage, but Pikoy just ended up trying to always attack her, so we had to get them separate cages. In addition, I don't think my lovebird loves me, he/she keeps screaming whenever I try to give it some food.
Also I'm curious- how can you tell if they are male or female?
