Tigers to the left, Possums to the right. The distance between Bali and Lombok is just 25 km but Asia’s woodpeckers, barbets and trogons are on one side, Australasia’s honeyeaters and cockatoos on the other. Huxley’s modification to the line tidies up a few problems, an excellent example being the genus Pachycephala, a literal translation – thick heads, more flatteringly known these days as the Whistlers. There are 32 species (following the Handbook of Birds of the World in this instance) and all of them are found to the east of Huxley’s version of Wallace’s Line.
When an Australians go birding in Asia they are confronted with not just with new species but whole new families. It can get confusing.
I’d been in Thailand for three weeks. New species were raining down the whole time. It was possible that I was missing the derisive laughter of the Kookaburra or my wife, or maybe the scent of eucalyptus. We were birding in the mangroves when I saw it, a little Aussie expat. It warmed the cockles of my heart springs …
I’ve seen Golden Whistler and Rufous Whistler in my own back yard and six other species in Australia. Some Whistlers have made it way out into the Pacific to the islands of New Caledonia, Tonga and Samoa but only one species straddles the mere 25 km that separate Lombok and Bali, the Mangrove Whistler. And it didn’t stop there, it can be found all the way up the Malayan Peninsula and then along the Asian coast from Vietnam to India.
It was then that I knew it was time to come home.
