Help needed. Cockatiel or parakeet?

[black dog]

I don't know if anyone can help me. My husband has just bought to birds which he has told ne are both parakeets. I'm not sure. If someone can help me I can email them photos of the two birds in question.

Thank you Dottie. That's a great help.

We've got one of each. Now I'll have to find out how to look after them.
