Budgies love attention, and if you're a chatterbox yourself they will like it even more. The more you talk to your budgies, the more devoted they become to you. Sometimes, you might even hear a flute concerto when they see you! A budgie is a social bird, and when there are lots of them together, they will all be twittering cheerfully together.
They are also likely to make a funny little noise when they see you approach with delicious food (like a juicy applepiece) and if you give it to them, they might make the same little noise every time you do that ^^
