Great picture, but here is information for anyone wanting to photograph the white-tailed jays. They have been moved to the parrot breeding centre offshow aviaries.
Wow! Jealousy from gentle lemur!!
I was obviously in the right place at the right time, as in the couple of times I've been back to the zoo since, I've not even seen a "green flash"!
Watched this gorgeous bird for about 20 mins, as it kept flying from the inside to the branch right in front of the viewing area, calling & flying back inside . Did this many times, the longest it stayed on the branch was 5 mins.
