Macaw Wings?

[Luke]

Can anyone confirm from these pictures that these are all Macaw feathers? One of them is labelled as such, but all the others are not labelled.

What do you reckon these are worth? Does anyone have an interest in purchasing them? If so, shoot me a PM.

My main intention of this post is to confirm what they are and to get an idea of value, not really trying to make a sale in this section of the forum.

Thanks for any good advice, as always.
