4 Nights in a DZ Sri Lankan forest reserve

Location: Galgirikanda area, nearest town, Galgamuwa.  Elevation ~ 200m.  Temperature 30-33 C.  Moderately humid, so unpleasant unlike in more arid conditions during the time of visit in early August 2017.  This is a flat area interspersed with rocks and hills up to a height of 700m.  Up on the rocks, the views are stunning in the morning and evening (see @Lanka_Wildlife for pics) and quite pleasant with cooling, sometimes strong winds, especially by evening moonlight, illuminating the landscape devoid of obvious man-made structures while I was there, as far as the eye could see.
Though mostly dry, there is enough rain to maintain verdure and feed wells, rocky hollows and puddles frequented by birds to bathe and drink in the evenings in particular.  The water is somewhat mineralised (“kivul”) leaving ones hair somewhat stiff and tangled.
The botany is dominated by indigenous plants (unlike the wet zone) including giant Euphorbia cacti, Toddy (Thal) palms (Borassus flabellifer) and dozens of species of tree such as Ebony, “Cone” (? with fruits similar to gal siyambala), Palu, Wood apple, “Timbiri” and Margosa (Neem) trees among others with the understory often dominated by curry leaf plants.  Indigenous Iluk "pitiyas" or plains still carry on, though these may be drowned by invasive mana in future.
The dust is hollowed by the pits of ant-lions.  The leaf litter crawls with orange insects like weevils (pictured).  There are long trains of black termites, colonies of larger biting ants that can weal the skin and leaf stitching red ants that fall from trees.  The dry zone cicada is especially active and infernal as the temperature rises in the afternoon.  Of butterflies there are quite a few including the slow flapping common rose (Papilio polytes).
The signature bird by day is the Indian Shama that sings beautifully at most times, loudest by dawn and dusk.  Several Shamas seem to compete in song around circles of 100-200 feet or so unless the same individual keeps moving around.  I asked a local resident who happened to be Danish whether the Magpie robin or the Shama was the better singer.  He replied that the Shama was the “Chopin” among bird singers, though you’d have room to disagree as he also enjoyed the song of the Indian nightjar (that kept him company by night).  Post sunset it’s the turn of Jerdon’s nightjar, repetitive but quite pleasant.  These birds seem to reply to calls from rivals within hearing range.  There are many other birds such as peacocks, jungle-fowl, black-capped bulbuls, brown-capped babblers and pompadour pigeons leaving aside commoner species (the Indian ring dove, all Sri Lanka barbets except the Yellow-fronted) and those unidentified.  The birds may be zoned as agricultural (ring dove, yellow billed babblers) living outside of the forest and forest birds themselves like the Shama.  Others such as Brahminy Kites, seem to occupy both habitats, especially associated with water.
The signature mammals include elephant (supressed by miles of electrocuted fencing), axis and mouse deer, jackals, macaques, porcupines, hare, giant squirrel and the loris.  Amongst those most easily encountered in the dark were hare, loris and mouse deer as well as either a toddy cat or dry zone golden palm civet up a tree.  The mostly invisible elephants seem to voice their despair by night, screaming like the chained giants they are devoid of the freedom to roam at their pleasure.  Their routes are blocked and at the time of the writing the government fails to provide them with elephant corridors to link up forest reserves.
Reptiles are more obvious and active in the dry zone than in the wet.  Skinks are very common in the leaf-litter as they rustle the ground in the search for prey, constantly chasing off fellow rivals.  Even the tallest trees can be climbed by the large land monitors and when descending they come down vertical trunks with the head down (upside down) like squirrels, suggesting that their rear limbs have phenomenal holding power for such a large and seemingly unwieldy lizard.  It’s quite confiding as long as one keeps a distance and can allow the cameraman almost near its face (at least the one I was looking at did).  I saw a painted lips agama, Calotes ceylonensis busily dashing down a tree with the head and chest area a stark black and white.  Then it noticed me and stood still, starring back, slowly turning a bright orange to replace the former white.  It carried on observing me for quite a while and it was I who had to give up.
There are miles of low trees in areas subjected to former chena cultivation but towards the rocks and hills unsuitable for cultivation, massive older trees carry on including forests of ironwood that may have been planted two thousand years ago.  In the crevices of these rocks, large enough for animals hides the mouse deer that may remain all day, observing people as they pass by.  You can detect them at dusk by torchlight.  The dry zone loris looks like it’s peddling a bicycle on all fours as it creeps around branches, both in the treetops and at knee level in bushes.  Its eyes dance like a pair of candle flames by torchlight from a tree or bush, but the mysterious animal is rather elusive and can disappear while you try and get camera ready.
The cone trees (whatever that species may be) drops hundreds of small brown fruits with seeds the size of a peanut.  Apparently the fruits were consumed by children but no more.  Similarly, the toddy palm leaves used to make the best roofing, especially if applied in several layers, but once again not used much any more.  I really looked forwards to constant showers to keep me sane, using a local Margosa (Kohomba) soap.  The evenings were the best times to chat with others on the rocks or in their little cottages, sipping tea to discuss politics, the weather and wildlife.

Outside forest reserves the land is cut up and bulldozed apace and the illusion of a sea of forest along with plains of soft native Iluk grass (pictured) quickly gives way to “progress”.
