මොණරා [Monara]/Indian Peafowl (Pavo cristatus)


Indian Peafowl is a common breeding resident of dry lowlands and some areas in the intermediate zone. It inhabits mainly open country, chena lands and scrub lands avoiding dense forests.  Its food consists of grains, leaves, grasshoppers, termites, and also small reptiles. Its usual feeding times are in the early morning and hour or so before sunset.  It roosts on trees during the night. Indian peafowl usually lives as small groups and spends their time mostly on ground walking great distances in search of food.  It flies mostly to cross an obstacle like rivers or to escape from sudden danger.  The breeding season is from December to May and male attains its long train during the mating season.  The peahen lays 3 to 5 eggs in a slight hollow on ground well hidden in dense shrubbery.

Garganey (Anas querquedula)


Garganey is probably the most abundant of our migratory ducks.  It is very common winter visitor as large flocks to the coastal lagoons, large tanks and marshes of dry lowlands. Small flocks can be found rarely in inland tanks and wet lowlands.  It is highly gregarious bird and often associating with other migratory ducks such as Northern Pintail, Common Teal and Northern Shoveler. It feeds on grain such as rice and also insects, crustaceans and mollusks, mostly during the night.  During the day time it spends far from the shore floating in a close flock (Henry G.M. 1998).  However diurnal feeding sometime up-ending in lagoons and large water bodies can be observed nowadays probably due to lack of ‘Duck shooting’ as it prevailed during Henry’s time.

Brook Hooktail (Paragomphus henryi)


Locally common dragonfly inhabiting fast flowing streams and rivers in submontane areas according to the de Fonseka (de Fonseka T., 2000) and hills and mountain regions as per bedjanic, M.,  et.al., 2007. However F.C. Fraser in 1933 noted that it is the commonest Gomphine in the island found in everywhere at all elevations (Fraser F.C. 1933). Probably what he meant is in suitable habitats as he elaborated further that it is a jungle insect usually found sunning itself on rocks in mid streams. With the recent distribution data of Brook Hooktail in the island M. Bedjanic concluded that P. henryi is not so common anymore, being known from around 70 localities concentrated in central and southwestern part of Sri Lanka (Bedjanic M., 2013) Above picture was taken at lowland rain forest stream of southwestern Sri Lanka (Indikada Mookalana – A heavily degraded secondary forest) with about 40m height above sea level (6°54.072'N, 80°09.724'E). Males Brook Hooktail can be easily distinguished from all others of the family by having long hook like down-curved anal appendages (insert). Female lack that expansion.

Angled Pierrot (Caleta decidia)


Angled Pierrot is an uncommon butterfly more partial to the jungle habitats of wet lowlands up to mid hills. De’ Abrera noted that Angled Pierrot is neither a ‘mud-puddler- nor a creature of open countryside (de’Abrera B., 1998). However mud-puddling individuals are not uncommon and also it inhabits open areas but always close to the jungles such as jungle foot paths (Above picture was also taken at such a habitat and it was mud puddling on a muddy foot path though it has flew away and settled on a near by shrub where picture was taken). It is frequent in jungle clearings and in shady streams (Banks J&J, 1999). It is a swift  flying insect which takes part in migrations.  The larva feeds on Maha-Eraminiya plants (Ziziphus rugosa) and Gouania microcarpa.

Flying Fox/Maa wawula (Pteropus giganteus)

Flying Fox or Maa Wawula in Sinhala is the largest bat in Sri Lanka with about 1.2m wingspan. It is distributed throughout the island excluding higher hills though it is a visitor to the higher hills during fruiting seasons. However  W.W.A Phillips noted that it appears to be absent, during the greater part of the year, from the Hambantota district (Phillips, 1980). Flying fox is a nocturnal mammal and has excellent night vision though it doesn't have echolocation like some other bats. During the day time it roosts communally in tall trees. Such a colony - usually located close to human habitations- may comprises hundreds or may be thousands of individuals. Flying fox exclusively feeds on soft pulp and juice of flowers and fruits (Excluding all citrus fruits) after solids are discarded having chewed the flesh. It covers immense distance in a night in foraging, ranging from 2 to 20kms. Often before feeding, it is said that they visit a river or lake to quench thirst, lapping up water as they glide over the surface (Phillips, 1980). Even though it is treated as a pest it also an invaluable pollinator of most fruit plants.

It is expert diver as well as a powerful flier. It keeps neck fully extended during the flight.
