What can they eat? (Other than seed, want to treat them if possible )

I'm looking after them for a friend that has become unwell

Thanks in advance!

Assuming these are canaries, here's a nice little website full of dos and don'ts

You don't know what they are? Where did you get them from?

Oh they're your friend's - sorry! I think they're canaries as well.

Thanks!
