One more STORK to add to the storks already here - I don't think I saw this one. I identified yet another of my Berlin Zoo photos, thanks to help from Aafke!!! (that is to say, Aafke identified the beast for me)
MARABOU STORK a large wading bird in the stork family Ciconiidae. It breeds in Africa south of the Sahara, occurring in both wet and arid habitats, often near human habitation, especially waste tips. It is sometimes called the "undertaker bird," due to its shape from behind: cloak-like wings and back, skinny white legs, and sometimes, a large white mass of "hair." (wikipedia)
I like the second shot, which, like my swan photos below, shows the bird all twisted up

Dale is right, but all birds have a dual voicebox; it's not unique to the Tui. They just don't necessarily all choose to harmonize with themselves. I'm saving up another spectacular example (my favorite birdsong) for when we get around to the Vs. Here's a nice article about birds and singing: http://www.pbs.org/lifeofbirds/songs/index.htmlthat's a great article! "Another performance ploy is to transmit the signal from above the vegetation by leaping up and calling from mid-air. The blue-black grassquit, a tropical grassland bird of South America, leaps clear of the grass during displays." coool.

Tui have a dual voicebox - the secret to how they can get such human-sounding voice qualities (parrots only have one voicebox, thus the "parrot voice") ...they're doing two things at once, like Tuvan throat-singers do; a sort of harmonizing with yourself. For anyone who has never heard Tuvan (Altai - Siberian) throat singing, here is a video of the most well-known Tuvan group. If you go to around 0:30, the throat singing begins. That is not an instrument; that's all him. It's really really hard to learn to do. That's just the whistle sound. They have others. http://www.youtube.com/watch?v=RxK4pQgVvfg&feature=relatedhere's another, wonderful group, performing (in Austin TX I think): http://www.youtube.com/watch?v=s9gBb1FzO2k&feature=relatedif you listen to that for awhile and then listen to Woof-Woof the Tui: http://www.youtube.com/watch?v=TqF33vc_q68&NR=1 you can better hear how it's using two sounds at once. They use the second "voice" to make overtones - so they can sound like people when they mimic human voices. Apparently Woof-Woof sounds VERY much like his keeper there - dale

"Widespread throughout its large range, the Lady Amherst's Pheasant is evaluated as Least Concern on the IUCN Red List of Threatened Species." (wiki-)
I don't know what the folks who make up the Red List have been spending their time looking at, but when I see the tail on that male, I am VERY, VERY concerned ;)
Thanks, Annette! Nice tail!!
