Extreme changes in temperatures,toxicity in food & pollution has resulted in conversion of a female pheasant in lucknow zoo in a male bird.According to vets,one of the ovaries in female birds might have  stopped functioning thus disbalancing the hormonal content in their body.In a normal female bird only the left ovary is seen functional but due to infection or any other  reasons if it deceases then right ovary becomes active & produces more testosterone resulting in male plumage.

 LIFE OF DANGER,DEATH BY STING--IT'S STEVE IRWIN

Renowned field biologist STEVE IRWIN,who was more commonly known as 'THE CROCODILE HUNTER',cheated death so many times when he tangled with man eating crocodiles or most easily handled full grown pythons but fell prey to a harmless sting ray on the fateful day of 3rd september 2006 when he was shooting for a documentary on Australia's great barrier reef.He came over the top of a sting ray & the barb went up in to his chest putting a hole in to his heart.Sting rays are normally placid & harmless,they posess barbs & poison on their tail as an organ of predation but not organ of attack.It's poison can cause extreme pain but quite unlikely that it killed steve. Irwin's daredivelry in his nearly 50 documentaries,shown on tv channel animal planet under the title The crocodile hunter,won him world wide accolades & audience.Irwin's parents use to run a small reptile park in queensland thus he learned to handle wild animals at the tender age of 6,by 9 he was catching crocodiles.He went on his honeymoon with wife terri irwin ironically trapping crocs,which eventually became the first episode of "THE CROCODILE HUNTER".
