Unusual-ology is a new post type which focuses on weird new articles/science areas that have cropped up and caught my eye.

I stumbled upon a very interesting article about a type of bird which has been dubbed as a ‘churkey’. The instant I saw the title I was immediately intrigued and felt I should write a post on these bizarre creatures.

The Transylvanian naked neck chicken has been recently assigned this nickname due to its unusual appearance; the ‘churkey’ has the body of a chicken but has the neck of a turkey.

Scientists at Edinburgh University, led by Dr Denis Headon, have set out to understand what has caused the chicken to have this unique appearance. The scientists have proposed that its appearance is caused by genetic mutation which was enhanced by a vitamin A-derived substance that is produced around the bird’s neck. Researchers were able to identify this as the protein BMP12 after obtaining DNA samples from numerous naked neck chickens from Hungary, France and Mexico (BBC, 2011). This protein causes the feather production to be suppressed around the neck area. The mutation was first found in domestic birds in Romania around a hundred of years ago. It is suggested that the loosing of feathers around the birds necks help the bird to remain cool in warm climates just like Ostriches (National Geographic, 2011).

This proves that mutations in animals are not always bad and from this example it has helped scientists understand developmental biology even more. This research could also have practical applications such as to produce poultry that can withstand hotter climates such as those in the third world countries.
