Brown-headed Gull (Larus brunnicephalus)

Brown-headed Gull is probably the most common gull of the island, which is abundant in northern coastal and lagoon areas during winter and rarely found in other coastal areas such as South-eastern part of the country. There are some summer loiters as well. It is gregarious and flocks can be seen resting on the water close to beach. It scavenges in harbours and also follows ships for ‘easy food’ thrown overboard from them.  Brown-headed gull can be easily distinguished from other gulls by dark-tipped red bill and black wing tips with two white spots near the edge visible when  flight. Brown hood appears of  breeding birds by the end of March.

An endemic bird inhabits only primary forests and near by home gardens in wet zone and foot hills. Uncommon and declared as a vulnerable bird in IUCN red list of threatened fauna and flora of Sri Lanka (2007). However feeding flocks consisting of up to 6-10 birds are not uncommon in buffer zone villages of Peak Wilderness (Sri Pada sanctuary) and Sinharaja forest. Though gregarious, pairs or solitary individuals are sometimes met with. It feed on insects [grasshoppers, leaf insects, beetles, etc.], caterpillars, shrub frogs, lizards and also some plant matter such as fruits. It is very noisy bird especially while hoping from branch to branch at all levels of trees from ground to canopy in search of foods. It is referred by a very interesting name of Kankaarassa by villagers in some areas around peak wilderness (Udamaliboda, Dikelikanda..etc) due to its  loud crakrakrakrak  call. Breeding season is from January to March and usually nest builds at the top of slender trees in forest and sometime even in home gardens. Once I have found a nest with eggs about 4-5 m above ground in top of small tree growing near a stream in a village. Group of three birds used to visit that during my observation period (only 2 days). Nest is some what similar to crows nest

Asian Openbill/විවරතුඩුවා/බෙල්ලන් කොකා [Vivaratuduwa/Bellan koka] (Anastomus oscitans)

Smallest stork of Sri Lanka with a    characteristic bill which has a gap between mandibles when it is closed. Common breeding resident of marshes, tanks, paddy fields and lagoons. Much common in dry zone low lands where it met with singly or in small parties and flocks. However it has been observed that recently open bill had expanded its distribution range to the wet zone specially wetlands around Colombo such as Muthurajawela, Bellanwila and paddy fields of Western province. Its food  consists mainly of mollusks. Also eat crabs, frogs, fish and other small animals found in its swampy habitats
Its peculiar bill is obviously an adaptation to facilitate extraction of soft body of mollusks from the hard shell. Regularly soar on thermal currents on sunny days and can be seen flocks circling up to great height in sky. It is recorded that this stork brings bivalve mollusks to ashore and eat soft parts when valves open due to hot sun. Breeding season is from December to March and nest in colonies sometime up to hundreds or more in top of low trees by water.
