I'm glad to see that Birding Babylon, a soldier-birder's blog, is still going.
I'm reminded of the time six years ago when an English friend was showing me around Winchester Cathedral. We paused in front of a 19th-century memorial plaque, where a British officer who helped to build Queen Victoria's empire was described as an avid amateur naturalist.
Putting on a plummy accent, my friend pretended to be that officer pointing out the rare Crested-Whatever even as the Zulus/Afghans/Whoever were charging his position. But all joking aside, we liked the idea of his being a soldier-naturalist.
The same with this guy, "J".
Even famed "milblogger" Michael Yon is a birder too.
