An avid birder, he decided to go to Papua New Guinea with Bill Whitlatch, an ornithologist friend of his from Montana Technical Institute. Three days into their trip, Bill netted a bird with an orange body and black wings and head for closer study. Dr. Westwood was very curious and asked Bill if he could have a closer look at the bird. After handling the bird and later touching his mouth with his hand, Dr. Westwood noticed that his fingers and lips were going numb. His mind immediately flashed back to the disastrous trip to Indonesia and he began to panic. Luckily, the symptoms faded before they progressed into anything more serious. His friend Bill used a key to identify the animal as a ‘pitohui.’ The pitohui are small, social songbirds that live in Papua New Guinea. They are generally about 23 centimeters long with strong legs and a powerful beak. Their encounter was the first time anyone had…arrow_forward
