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 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.

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 pusillaLimnophila 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.

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.

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/Brahminy Mynah/බ්‍රාහ්මණ මයිනා[Brahmana Maina](Sturnia pagodarum)


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.

But in the protected areas such as in national parks, it is active even during the day time, mostly in the morning hours. Black-naped Hare is an almost entirely herbivorous mammal and feeds on grasses, shoots, young leaves etc. It doesn't have definite breeding season and produces one or two young ‘leverets’ at any time of the year.
