Tailed Jay/Green Jay (Graphium Agamemnon menides)
Tailed Jay is a common butterfly found in
all elevations of the country throughout the year. However it is much common in the wet zone. It flies very fast and only stops a very short time at each flower.
Also when disturbed it take off vertically to considerable height before fly
away. So that Tailed Jay is considered as a very difficult butterfly to
photograph. The larva feeds on various plants of family Annonaceae such as Annona muricata (කටු අනෝදා/කටු ආත්තා/රට අනෝදා/Soursop), Annona
reticulata (අනෝදා/වැලි ආත්තා), Annona squamosa(සීනි ආතා/අනෝදා/Sugar Apple), Annona glabra (වෙල් ආතා/Pond Apple/Alligator Apple/Monkey Apple), Annona cherimola, Uvaria zeylanica (පාලඟ/පලු කන්),Uvaria macropoda, Uvaria narum, Uvaria semecarpifolia, Uvaria sphenocarpa, Artabotrys zeylanicus (කලු බඹර වැල්/පටික වැල්/යකඩ වැල්), Artabotrys hexapetalus, Polyalthia korinti (මීවැන්න/උල් කෙන්ද), Polyalthia longifolia (දේවදාර/ඊ පෙත්ත/ඕවිළ/ඕලිල), Polyalthia suberosa, Polyalthia cerasoides, Miliusa indica (කෙකිළි මැස්ස/කුකුළු මැස්ස), Miliusa tomentosa, Goniothalamus gardneri and Xylopia championii.

Spot-billed Pelican/තිත් හොට පැස්තුඩුවා/ඔටුමානා[Thith-hota Pasthuduwa/Otumaana] (Pelecanus philippensis)
Spot-billed Pelican is a common breeding
resident in tanks, lagoons and marshlands of the low country dry zone. Birds
originally released from National Zoological Garden of Dehiwela have established a breeding colonies in and around Colombo marshy areas in the wet zone also. It lives as flocks from two or three birds
to a hundred or more. It spend much of its time in fishing, usually as a flock. The breeding season
is from March to May and the nest is a large platform of sticks and reeds,
placed on trees growing in flooded areas or swamps. Usually several nests can
be seen in a single tree together with other storks, herons, egrets and
cormorants. It is a strong flier and sometime flies great heights, usually
forming V formation. Although it is common in Sri Lanka Spot-billed Pelican is considered as a globally endangered species.

Grey Pansy (Junonia atlites)
Common butterfly found in everywhere from
lowlands to about 1000 m a.s.l. Grey Pansy is a migratory species and Ormiston
noted that it appears up-country usually in October, before the regular flights
begin, and the swarms only lasts a few days (Ormiston W., 1924). The larva feeds on Yamazakia pusilla, Limnophila repens (අඹවිල), Hygrophila auriculata (කටු ඉකිරි/නීරමුල්ලිය), Lindernia anagallis, Lindernia crustacea, Lindernia antipoda (විල/Sparrow false pimpernel) and Limnophila indica.

Brown-breasted Flycatcher (Muscicapa muttui)
Brown-breasted Flycatcher or as it was previously known as Layard’s Flycatcher was initially discovered by E. L. Layard
around 1854 from Pt. Pedro of Sri Lanka . While quoting Layard, W.V. Legge in his
monograph on Sri Lankan bird - A History of the birds of Ceylon- mention that
after describing the specimen brought to Layard: “ I name this new species
after my old and attached servant Muttu, to whose patient perseverance and
hunting skill I owe so many of my best birds. This one he brought to me one
morning at Pt. Pedro during the month of June.”(Legge W.V. 1880) That is how it got its 'Tamil' zoological name Muscicapa muttui.
Brown-breasted
Flycatcher is a rather uncommon winter migrant to the wet zone lowlands to the lower
hills while local and rare in dry lowlands and mid hills. It is a solitary bird
often found in the vicinity of streams in forests and well-wooded areas. It can
be easily distinguished by superficially similar Asian Brown Flycatcher by
Flesh colored lower mandible, legs and feet with white throat with dark
moustachial stripe in contrast with dark brown legs and dark tipped pale lower mandible
of Asian Brown Flycatcher. It flies out and catches small flying insects
usually returning to the same perch or to a neighboring one since it is very attached to its territory.

Dark Grass Blue (Zizeeria karsandra)
An uncommon butterfly found in grasslands
from sea level to about 1500m elevations. It can be easily distinguished from bit

the under side of the fore wing. Its larva feeds on Amaranthus blitum, Amaranthus viridis, Amaranthus spinosus (කටු තම්පලා/Spiny amaranth/Prickly amaranth), Coldenia procumbens, Sauropus bacciformis (බිං දෙළුම්/ඇත් පිටවක්කා), Glinus oppositifolius (හීන් අල), Tribulus terrestris (සෙම්බු-නෙරෙන්චි/ගොකටු) and Hypertelis cerviana plants.

දුම්බොන්නා [Dumbonna]/Indian Roller (Coracias benghalensis)
Indian Roller is a common breeding resident
in dry lowlands up to lower hills, while uncommon and local in wet lowlands. It
is common mostly in coconut plantations, chena cultivation and such open areas,
usually as solitary birds or in pairs. It is known as Dumbonna among Sinhalese
people meaning Smoke-drinker since it has a habit of flying over the grass and
shrub fires usually when burning jungles for chena cultivation to catch
grasshoppers, beetles and other flying insects disturbed by the fire. Indian Roller
spend much of its time sitting on a telegraph wires, fence posts or any such
vantage points and flying down to catch its prey, which consists of
grasshoppers, beetles, lizards and such little animals. It breeds from January
to June laying 2-4 white eggs in a tree hole of a dead tree or in a rotten palm

වල් ඌරා[Wal Ura]/Indian Wild Boar/Wild Pig (Sus Scrofa)
Wild boar is distributed throughout the
island wherever dry zone scrub lands or wet zone forests provides it with enough
cover, from coastal lowlands to the higher hills. It occurs in herds sometime up
to around 30 or more individuals in dry zone national parks while rather small
herds or solitary animals occurs in wet zone forests. It is an omnivorous mammal and scavenge on carcasses of dead animals, kill and eat snakes, worms, eggs and
young of ground-nesting birds and also feeds on fallen fruits and uprooted
rhizomes etc. It causes lot of damages to the chena cultivation, paddy fields,
home gardens and other plantations during its night time forays in search of food.
Wild boar is a prolific animal and breeds at least twice annually and W.W.A.
Phillips noted that it is always the last of the larger mammals to be ousted
from a district where the forest is being opened up (Phillips W.W.A, 1984). Generally the herds are composed of sows with
their young of all ages and the older adult males live solitary or form small
parties on their own and join the herds of females only to the mating. They feed
usually early morning and late afternoon while lying up in a shade during heat
hours of the day. It also feeds during night. Leopards, crocodiles and pythons
can be considered as its enemies other than Man. Leopards mostly take
young piglets whenever the opportunity occurs and there are instances of
desperate fights between leopard and old boars sometimes end up with leopard being killed.

Brahminy Starling is an uncommon winter
migrant to the open and shrubby areas and cultivation of dry lowlands mainly in coastal areas, though unconfirmed reports available of breeding in nineteenth
century. Occasional sight records also
available from wet lowlands, apparently on their way to the dry lowlands from India where it breeds. It lives in flocks and
feed on the ground while large flocks gather at a communal roosting place in
the evening. Brahminy Starling mainly feed on grasshoppers and other insects,
but it also eats fruits and drinks nectar from certain flowers.
