Sri Lanka’s endemic enigmas

Where earth’s greatest landmass narrows to a subcontinent, below where mountain thrusts up rock to earth’s highest peak and river runs down to dry plain, just beyond where land tips into ocean, in one slip of forest in the wet mid-hill tropics that rise up on a small island once bridged to south-east India, behind the obscuring branch of one jack tree, there is a blue magpie.

We’ve come a long way for this bird. It is truly magnificent though. Don’t think your usual black-and-white, garden-menace job. The Sri Lanka magpie is of quite another order: blue body, blue tail – true blue, bluest in the forest – head and wings of dark tamarind, feet and a heavy corvid bill the colour of pomegranate arils. The same red neatly circles the eye. It’s a bird to travel for.

In cloud forest, good views of anything can be hard; it’s alarm and frenzy in the tops, exotic calls and brief flashes above. Tall is habit in a place like this – trees reach 40, 50 metres high, their boles straight up into tree domain – but such thick vegetation down here obscures verticals and heights.

The trick is to stand still, tune in to what you hear. In this valley, dawn is a broad coming like a passing eclipse. We stand in the green air on the edge of the clearing before the heat arrives, waiting for birds at first light. Orange-billed babblers are easy enough – their fuss and squabble shake the foliage with monkey-vigour. They are joined by the odd ashy-headed laughing thrush or drongo. Higher up, there are white-faced starlings and hill mynas.

The rasp of the magpie gives it away. And where there’s one, more follow. We watch six in total, a raucous mob tailing each other from tree to tree for just two minutes, so plainly blue you wonder how they do such a good job of disappearing.

We’re very pleased to see them. The thing is, you won’t find any of these birds anywhere else. Not just in Sri Lanka, but nowhere else in the world. Like so much of the immense biodiversity on this island – trees, insects, amphibians, reptiles, flowers, butterflies, mammals, birds – the blue magpie is an endemic. Sri Lanka’s ancient insular existence has evolved a remarkable ecology of highly specialised creatures. Amongst birds alone, of the island’s 27 full endemic species (there are subspecies too), most of these can only be found in the wet-zone hills in the far south, and some of these, even, only in isolated pockets of this territory. Only sixteen years ago, in fact, a new owl species was discovered in these forest fragments that survived colonial rule. It’s a reassuring sign in this age of loss and destruction.

Find this little lodge near Deniyaya on Google Earth, scroll in, then right out to see India, and Eurasia, and the whole globe. This is to know the fragility of every part of all things, yet wonder that the infinitesimal can still hold mysteries.
