A rare breeding resident inhabiting undergrowth of forests and well wooded areas from wet lowlands to higher hills. Scarce and local in riverine forests in the dry zone. It feeds on insects, worms, etc mainly on the ground, skulking in the undergrowth while turning over leaf litter. It lives as pairs or as solitary birds. The breeding season is from March to April and again from August to September. It build a nest - an untidy mass of twigs, moss and grass- placed in a crown of tree fern or fork of a sapling where it lays two eggs.

First physical observation of Petinomys fuscocapillus (jerdon, 1847) with photographic evidence from Sinharaja World Heritage Site
Small flying squirrel or Heen Hambawa (හීන් හම්බාවා) in Sinhalese is one of the rarest nocturnal mammals of heavy forests of the lower foothills
to higher altitudes (Yapa A. & Ratnavira G., 2013). As per Phillips W.W.A.
its range limited to the hills at medium altitudes with extremely local distribution
(Phillips W.W.A., 1981). Further he has given a list of places from where it
had been recorded up to then (Table 1). Other than Sri Lanka it is found only in
Western Ghats of India and there also it was re-discovered in a coconut grove
in Kerala state in 1989 after one hundred years and it was thought to be
extinct in India till then (Yapa A. & Ratnavira G., 2013 & Nanayakkara
et.al., 2012 quoting Kurup, 1989). In
2007 Jayasekara et.al. recorded it from Sinharaja forest with a black &
White picture captured by a camera trap placed on a fruiting tree to assess
fruit consumption by birds and mammals of a tropical rain forest (Jayasekara
et.al., 2007). Most recent observation
of it is from Laggala-Illukkubura road of Knuckles range made by Nanayakkara
et.al on 26th January 2013. They have observed and photographed a
single specimen while it was feeding on tender part of the shoot and leaves of a climber at 2130 hr on a tree 9m above ground level in a well-developed
semi-evergreen forest habitat . They have not
observed gliding of the animal (Nanayakkara et.al, 2013). Hitherto only color photographs available of this illusive mammal was from them and it was the first physical
examination of this species from Sri Lanka after 78 years.

Food:
It is believed that Small flying squirrel is feeds on wild
fruits, berries, nuts, shoots and young leaves and possibly also sappy bark of
certain trees (Phillips W.W.A., 1981)
Habits:
Small flying squirrel is purely nocturnal and arboreal and it
spends day time in a hole of a tree trunk or branch of a large tree. It carries
its tail curled over its back when stationery and feeding. Not much information
available on its breeding and it is said that two young are born in a hole,
lined with vegetable fibres, etc. in which their mother lives day hours.
Observation and
discussion
On 14th January 2014 we were able to observe and
photograph a Small flying squirrel at a place close to the Sinharaja forest
reserve (Outside the protected area) from around 11.30 PM to 3.00AM of 15th
January 2014 (It was not at the site continuously during the observation period
but appeared there time to time). It was observed about 2m above the ground while feeding probably on young shoots and leaves of a mango tree (Mangifera indica). Short distance (less than 3m) gliding
also noticed at least once during the observation period. Most of the
time except when moving from one place to another it kept its tail draped over
its back. It was not much shy and not paid
much attention toward camera flashes and torch
lights. According to all available published data
this might be the second instance of the physical observation of this rare
mammal in recent history with photographic evidences and first instance of observing it in Sinharaja forest reserve area though existing of it there has been already proved with camera traps (Jayasekara et.al., 2007). Most important fact here is
that this observation was made not inside the dense forest but small secondary forest area close to Kudawa
conservation center office and this observation highlights the important of conserving not only Sinharaja
forest itself but also buffer zone forest areas surrounding the Sinharaja
heritage site.

Hump-nosed Lizard/Lyre-headed Lizard/ගැටහොඹු කටුස්සා/කරමල් බෝදිලිමා/බොහොඬා[Gatahombu Katussa/Karamal Bodilima/Bohonda](Lyriocephalus scutatus)
Hump-nosed Lizard is an endemic arboreal lizard found in shaded forests and adjoining well wooded home gardens and plantations from wet lowlands to mid hills (up to about 1600m a.s.l.). It feeds on insects[termites, butterflies, moths], earthworms, young shoots and buds as well as fruits on both trees and on land. It is a diurnal lizard and during night ascending high up trees to sleep. If cornered it opens its mouth wide to show the bright red color inside, change body color and also practicing death feigning.

රන් දෝතළු[Ran dothalu] (Loxococcus rupicola)
Ran dothalu is a rare endemic palm confine to the south-western rain forests from lowlands to hills (300 to 1500m a.s.l.). It can be found as small populations on shady rocky outcrops near streams. Seeds use as a substitute for Betel-nut palm for mastication with betel. This palm recently become a popular ornamental plant and despite the fact that it is protected under the law, illegal over exploitation widely practices and hence become an endangered plant.

Frogmouth/මැඩිමුහුණා[madimuhuna] (Batrachostomus moniliger)
Frogmouth is a rare breeding resident found in dense forests and forests edges in all climatic zones while scarce in hills and comparatively common in the wet zone. It is a strict nocturnal bird and spends the day perch across a branch with beak pointing upwards and the facial plumes erected forwards looking rather like a broken branch. It feeds mainly on insects like beetles. The breeding takes place from January to March and again from August to September. The nest is a small pad set on a horizontal branch, well camouflaged with lichens and barks which support a single egg which is brooded during the day by the male bird (probably the female broods at night - (Henry G.M., 1998))

Kelaart's Dwarf Toad is an endemic frog inhabiting wet zone forests and adjoining well wooded areas from lowlands to sub-montane region. It is a terrestrial species though occasionally climbs on trees and walls of the rural houses. Kelaart's Dwarf Frog active mainly during the night and in the day time it hides under rocks, decaying logs and among leaf litter along stream banks.

New distribution record for Libellago corbeti (van der Poorten, N., 2009)
Introduction
Libellago corbeti (Ebony Gem) is an endemic damselfly first identified in
July 2007 from two male specimens seen near Kudawe and later on another two females from
same locality in April 2008. It was described as a new species by Nancy van der
Poorten in 2009 (van der Poorten, N., 2009). Additional sightings of it from the
type locality as well as from several other forests of the south western wet
zone were recorded subsequently (van der Poorten, N., 2011). Those additional
places are -
1)
Near the start of the Moulawella nature trail, river
running down from the Kudawa entry point and near the stream beside research
station in the Sinharaja forest reserve.
2)
A stream in the Haycock hill – Hiniduma.
3)
A stream in the Morapitiya forest reserve.
4)
A stream near entrance of Kanneliya forest
reserve.
5) A specimen collected in 1892 by Col. Yerbury from
Kottawa (Probably the Kottawa forest reserve of Galle) and now deposited at
Natural History Museum London.
Observation
During a field visit to the Katepola, a remote village in
Rathnapura district on 25th of December 2013 we could photograph a male
specimen of Libellago corbeti in a stream - a upper tributary of Kalu river - beside a rubber plantation. Eventhough the stream running through rubber
estates and home gardens, stream itself and banks are well wooded and home to
considerable number of fauna and flora including several endemics. Libellago corbeti both males and females have been observed in that stream since May 2013 (Ishara Harshajith Wijewardhane, Personal communication, December
25, 2013)
Discussion
Hitherto
all published records of Libellago corbeti are from dense rain
forest streams and this might be the first sighting of it from a disturbed
habitat and also from a site with least protection from environmental authorities,
unlike all other places mentioned above with considerable protection under the
law. This record of it from
further north of the type locality and all other additional places indicates that
it might be distributed in wider area and also not very rare as previously thought. Currently it is categorized as a critically endangered species (van Der Porten
N. & Karen Conniff , 2012)
