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.

Common breeding resident found in forests, open wooded areas, gardens and cultivation from wet lowlands to mid hills, and locale in the dry zone.  As all other barbets it is a fruit eater and out of the breeding season forms scattered flocks especially in the neighborhood of fruiting trees such as Bo, Nuga, etc. Otherwise it is mostly encounters as solitary birds or as pairs. The breeding season is from January to June and it lays 2-3 white eggs in a tree hole dug into the lower surface of a sloping branch rather than into an upright post. Some ornithologists consider Crimson-fronted Barbet as an endemic bird to Sri Lanka while others believe it as a proposed endemic which need to be verify taxonomically.

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.

When swimming on the water surface it swims with only the head and neck exposed and hence its vernacular name snake-bird. It feed on fish and catches them with its needle-sharped bill while swimming under water. Darter often associates with other cormorants when feeding though solitary birds are not uncommon. It is expert diver as well as a powerful flier. It keeps neck fully extended during the flight. The breeding season is from December to March and it breeds in colonies often with other water birds, building a nest in trees near water.

Amber-winged Glider (Hydrobasileus croceus)


A very rare dragonfly recorded only once in Sri Lanka from the Kandy according to the Terrence de Fonseka (de Fonseka T., 2000). However 2012 National red list listed it under Near Threatened category probably due to records of more occurrences of it in the island than previously thought. Both sexes are similar and it can be easily identified by the amber color patch on the hind-wing. It is said that it breeds on weedy tanks and where males can be found waiting for females( de Fonseka T., 2000 quoting Fraser )I have encountered two specimens on 16th February 2013 close to the Kalu River at Dombagaskandha forest reserve in Ingiriya. First one was flying about 2-3 m above the ground (Time - Around 1PM) close to a tributary of Kalu River. Second one was resting on a road side shrub during the evening (Time - Around 4 PM).

Western Reef Egret (Egretta gularis)


Rare but regular winter migrant to the coastal lagoons, mangroves, estuaries and shores, mainly in the north. There is a 19th century record of breeding of Western Reef Egret near Chilaw in May and June by Layard. But since then no such records and now it is considered as exclusively a winter visitor to the country. Western Reef Egret occurs as two color morphs: dark morph with dark ashy grey plumage and pale morph with pure white plumage [Closely resemble to the Little Egret but can be distinguished by shape and color of the bill] or white plumage with grey patches. It is usually a solitary bird or lives in pairs, but sometimes associates with flocks of Little Egrets.
