You can make guesses at the forum.
What are some of the ways that you can tell?
Is it the colour? Colour might be good, but so many birds have several different colour mutations.
Is it the eye? Eyes can tell you a lot – look at the colour – look for an eye ring.
Can you see the beak? What colour is the beak?
Please join us in the forum and see what everyone thinks these birds are - give your own guesses. Or - maybe you know and you don't have to guess. Let us know what you think.
After you have taken your best guesses, you can find the answers at Answers.
