I really like the colours on these guys, and this is nice and sharp. Great eye contact, and I think Dave has covered the main point of the colour cast.
Dave's repost nicely fixes the exposure issue, but there is still a bluish cast to the iamge. You can add some more yellow (reduce blue) in Color Balance as an option. Good pose, and nice habitat. I like the foliage throughout, but don't care much for the OOF branch crossing the bill. I also like the big displaced feather :-)
