Here is the beautiful Brown-headed Paradise Kingfisher, one of my favorite birds. I beleive it is one of the prettiest kingfishers in the world, and surprisingly, you can see it just 60 minutes away from Port Moresby International Airport.
You may be arriving from Europe or USA and in next 1 or 2 hours, you will be with the beautiful birds like this one. Best birding season runs from April to October. (last bird wacther enjoyed very much in November though...)
