on your Budgie! Would love to see a pic, perhaps try taking one without a flash?
I think as long as you know the basics, give your baby alot of love, time, and patience, he/she will thrive.
If yours is a youngster don't forget to offer them organic veggies, since they are more agreeable the younger they are.
Be sure to keep toxic/chemical things away from it (certain houseplants, cleansers, Febreeze, markers, glue, smoke, Teflon pans, hairdryers, etc - almost anything with a smell).
I had great success with clicker training. I love the book Getting Started Clicker Training For Birds by Melinda Johnson and highly recommend it.
Rotating toys/the cage around evey few days will make your bird more socialized, they tend not to be territorial then and it helps avoid breeding behaviors.
Good luck. Remember to have fun with your bird. The more you gently talk, play, spend time with it, it will learn to love & trust you.
