PHNOM PENH :  A new species of bird with a distinctive orange-red coloured tuft of feathers on its head has been found in Cambodia’s populous capital city, conservationists said on Wednesday. The remarkable discovery of the Cambodian tailorbird, or orthotomus chaktomuk, in Phnom Penh and several other locations including a construction site just outside of the city of 1.5 million people has astounded conservationists.
