Annual Wader Studies Workshop at Bundala

Bundala National Park is one of the best places to watch birds, especially the waders and some other waterbirds, in the South. Many of the amateur bird watchers face difficulties in identification of Waders (Shorebirds). Therefore, annual field workshop of the Field Ornithology Group of Sri Lanka on the wader studies at Bundala is an important event for its members. A team of 22 FOGSL members headed by Prof. Sarath Kotagama participated in this event from 28th November to 01st December 2009. Due to heavy rains prevailed in the area few days ago, water level at the Bundala lagoon and other surrounding water bodies were high. Hence, numbers of birds on the mudflats of Bundala lagoon were comparatively very low. However, members were able to record a total of 121 species including 21 wader species during the four day period. During the Workshop, members actively participated in bird identification sessions, bird counting exercises and also the data analysis on simple studies. Several seminars were also conducted for the members during the period. Participants: Mr. Janaka Dissanayaka, Mr. Ashoka Jayasekara, Miss. Uraji Karunaratne, Ms. Mallika Peeris, Mr. Adrian Gabriel, Ms. Sujatha Mayadunnage, Mrs. Cheryl Silva, Miss. Ayanthi Samarajeewa, Ms. D.H.M. Wijeratne, Mr. S.D. Pemaratne, Kid.

It is DECEMBER again - the Bird Counting Month..!!

Bird Counting Month is an opportunity for you to pay attention to the birds. In ‘December’ Sri Lanka will be having the peak number of birds as it is middle of the migration season, hence the best time to do this exercise.

Participating for the Bird Counting is simple. What you have to do is to make a list of birds that you have been able to identify in a given location and email the records to fogsl@slt.lk or directly feed the data into "Sri Lanka Birds" database (http://www.worldbirds.org/srilanka). The list should include the date, time, location, weather at the time, the habitat that the bird observation is carried out, and the name and contact details of the observer. You can also include the number of each species seen at the location, so that this number can be used roughly to compare the population next year.

If you participated the Bird Counting last year, do the counting in the same area this year too. The list of birds and numbers can be tallied with the last few years. If the conditions of the counting are same, then yourself can have an assesment of the status of birds in that area.

Pass the message.. Get your friends to join too…!!
For more information on 'how to participate', read the announcement on the 'Bird counting month 2008'.

Ivory-billed Woodpecker and musicians

The news of the rediscovery of Ivory-billed Woodpecker, has stunned ornithologists world-wide. It was a surprising story as the species was assumed to have gone extinct in North America since the last confirmed sighting in 1944. This news affected not only bird watchers and scientists, but also musicians. This is the result; a song dedicated to Ivory-billed Woodpecker by ‘The Moss Piglets’.

Fynbos Plant Kingdom and the Bird diversity in Cape Peninsula – South Africa

[FOGSL member Nishanthi Perera recently visited Cape Town, South Africa to participate at the DIVERSITAS 2nd Open Science Conference on ‘Biodiversity and society: Understanding connections, adapting to change’. She wishes to share her experience on Nature of Cape Peninsula with our readers.]
South Africa is the only country in the world with its own floral kingdom, which is known as the Cape Floral kingdom. Of the six floral kingdoms of the world - Antarctic, Australasian, Boreal, Neotropic, Paleotropic and Cape - the Cape is the smallest and richest, with the highest known concentration of plant species. This floristic Region is home to the greatest non-tropical concentration of higher plant species in the world, with 9,000 species crammed into its small extent. Incredibly, more than 6,200 (69 percent) of these species are found nowhere else in the world. Furthermore, five of South Africa's 12 endemic plant families and 160 endemic genera are found only in this region. Table Mountain alone has almost 1,500 species in 57 square kilometers. The area is one of the 34 global hotspots, and is one of the only two hotspots that encompass an entire floral kingdom (the other being New Caledonia).The Fynbos comprises of hard-leafed, evergreen, and fire-prone shrubs that thrives on the region's rocky or sandy nutrient-poor soils. The tallest shrubs are the proteoids and are 1- 3 meters in height and have large, leathery leaves. South Africa’s national flower, the King Protea (Protea cynaroides), is perhaps the most famous species of Fynbos, along with Ericas and reeds (which is known as Restia). The Fynbos Biome bears a certain resemblance to the vegetation in other Mediterranean or winter rainfall regions, as it has to adapt to wet winters and dry summers. The Table Mountain National Park as well as the Kristenbosh Botanical garden is a showcase for this flora, with representative examples of all the major communities. I had the opportunity to visit both places and became mesmerized with the colorful splendor they present.
The mountains may appear to be a botanical paradise and a zoological desert at the first glance, as you won’t find any of Africa’s Big Five (lion, elephant, leopard, black rhino and buffalo) here, but rather a number of smaller mammals such as baboons, jackals, duikers, and bontebok and gysbok antelopes, which are dependent on the Fynbos for their survival. Other Fynbos species include the rare ‘Geometric Tortoise’, and the endangered ‘Table Mountain Ghost Frog’. Beneath the shrubby flora there is a teeming world of small creatures, which lives in partnership with the plants. For example, some Fynbos species rely on Pugnacious ants to burry their seeds protecting them from fire and predators. In return, the ants are rewarded with a “snack” called 'Elaiosome' (fleshy structures that are attached to the seeds) by these seeds.
The avifauna of the Cape Floristic Region is characterized by low diversity, most likely the result of structural uniformity in the vegetation and a shortage of available food. Of the 320 or so regularly occurring species of land birds here, only six are endemic. Nevertheless, the area is considered an Endemic Bird Area by BirdLife International.
During a bird watching trip on the 17th October, we were able spot more than 120 species. When strolling among the beautiful flowers at the Kirstenbosch Botanical Gardens it is quite easy to observe some important Fynbos endemics such as Orange-breasted Sunbird, and Cape Sugarbird. Cape Francolin, Double-collard Sunbird, Southern Boubou, Cape Thrush, Cape Robin-chat, Karoo Prinia, and Speckled Mousebird are some of the birds abound the gardens. Raptors such Black Eagle, Forest Buzzard, Peregrine Falcon, Rock Kestrel were also observed. Two Spotted Eagle Owls were also found roosting on a tree. One of the most distinctive brides at Kristenbosh is the Helmeted Guineafowl, while species such as Cape Suprfowl, Egyptian Goose and Hadeda Ibis were also spotted walking and flying among the bushes.
After Kristenbosch, we stopped at the False Bay Ecology Park, which is a leading conservation, environmental education, recreation and ecotourism centre. The park is home to around 235 bird species including Sacred Ibis, Glossy Ibis, Lesser Flamingos, and large number of waders. As in Sri Lanka the Flamingos do not breed at the site, but many juveniles resided within this wetland throughout the year.
Around 30 African Jackass Penguins, which are globally threatned, were spotted at the Boulders Beach, which is part of the Table Mountain National Park. Today there are an estimated 11,000 breeding pairs of Jackass Penguins at this location. According to the tour operators one can also swim amongst these Penguins, but the cold Atlantic waters prevented us from attempting it. The Cape region has been heavily settled for several centuries, and large areas of natural vegetation, particularly in the lowlands, have been cleared for agriculture and urban development. Invasive alien species, both plant and animal, together with altered fire regimes, pose great threats to this eco-region.
The Cape Floral Kingdom contains eight protected areas which comprise the Cape Floristic Region World Heritage Site that also includes Kirstenbosch National Botanical Garden, the first time that a botanical garden has been recognized as a world heritage site for its biodiversity.

‘Revised Avifaunal List of Sri Lanka’

Download pdf version of the “Revised avifaunal List of Sri Lanka” by C.D. Kaluthota and Prof. S.W. Kotagama at the web site of the Field Ornithology Group of Sri Lanka.

Last taxonomic list of birds was published in 2006 as a part of National effort to document the fauna of Sri Lanka. However, due to recent advancement in researches in the region, taxonomy of birds undergone several changes.

Since, FOGSL now adopts the standards devised by BirdLife international on the avian taxonomy, it was necessary to revise the Avifaunal list. “Revised Avifaunal List of Sri Lanka” discusses the taxonomic changes in family level as well as species level, those relevant to Sri Lanka. It also provides complete list of birds recorded from Sri Lanka including new additions in recent years.

Long feared extinct, rare crow rediscovered in Indonesia

Known to science only by two specimens described in 1900, a critically endangered crow has re-emerged on a remote, mountainous Indonesian island.

The Banggai Crow (Corvus unicolor) was thought to be extinct until Indonesian biologists finally secured two new specimens on Peleng Island in 2007.

An ornithologist who specializes on the birds of southern Asia, Pamela Rasmussen studied the two century-old specimens known as Corvus unicolor in New York's American Museum of Natural History. She compared them to the new crow specimens in Indonesia's national museum, to lay to rest speculation that they were merely a subspecies of a different crow.

The rediscovery was spearheaded by professor Mochamad Indrawan of the University of Indonesia, chairperson of the Indonesian Ornithologists' Union, who conducted ecological field studies. He was assisted by collaborator Yunus Masala and by the Celebes Bird Club, members of which secured the new specimens that are now catalogued at the Museum Zoologicum Bogoriense in Java.

A photo of the Banggai Crow debuts this week in volume 14 of the influential Handbook of the Birds of the World. In the meantime, Rasmussen, Indrawan and colleagues have submitted the detailed paper confirming the species' rediscovery for publication.

Sight record of a Pectoral Sandpiper Calidris melanotos at Bundala National Park

During a visit to the Bundala Salterns (Bundala National Park), on 29th September 2009, I observed a Pectoral Sandpiper.

There were a limited number of waders in the Bundala Salterns although the water level was low exposing a large area of mud flats. In the early morning of 29th, I decided to visit the Western end of the salterns, where I had seen a few small flocks of waders on the previous day. I observed a few of these flocks which consisted of the familiar species. While scanning with my spotting scope, I saw a larger flock of around 300 birds, at the distant corner of the salt pan. Although it was far away, I walked to the mudflat. The flock consisted of common species such as Curlew Sandpipers, Common Redshanks, Lesser Sandplovers, Kentish Plovers, Little Stints, etc. Three Great Knots which is uncommon in the area were also observed. Hence, I decided to have closer look at the flock.

I could approach to within 20m of the flock without disturbing them. I then saw a bird, which I have never seen before. Its JIZZ suggested that it was a sandpiper. It moved with the Curlew Sandpipers. The bird was slightly smaller than the Curlew Sandpipers and stayed within two feet of the shoreline. During my observations it did not leave the water.

The bill was short and slightly down curved, showing a yellowish base. The upperparts were brownish and the underparts excluding the breast were white. The upperparts and crown appeared streaky with a slightly rufous tinge. The breast was nicely streaked and the streaks stopped abruptly at the lower breast marking a sharp demarcation. Its legs were yellowish green. As the bird was new to me, I referred the field guide by John Harrison, which I had with me. The species closest in appearance of the “new” bird was the ‘Sharp-tailed Sandpiper’. However, the bird lacked the white eye-ring and prominent eye brow that widens behind the eye of the Sharp-tailed Sandpiper. The flock was disturbed by a low-flying flock of Spot-billed Pelicans and the wader flock flew away. However, I managed to observe the bird for nearly 30 minutes and sketch it. After I reached our camp site, I referred “Shorebirds: an Identification guide to the birds of the world” by Peter Hayman, John Marchant and Tony Prator. I found that the specimen was undoubtedly a Pectoral Sandpiper. One of the characteristics observed by me viz. “the streaking on the breast is sharply demarcated from the unmarked white belly, with the line of division running across the lower breast” was mentioned in this reference. Hence I identify the bird as a Pectoral Sandpiper in non-breeding plumage.

The Pectoral Sandpiper winters mainly in South America while a small population visits Australia and New Zealand. It breeds in Siberia and North America.

This species was first recorded from Sri Lanka by a group of visiting bird watchers at Weerawila in March 2002. Thereafter, to the best of my knowledge, there were no reports of this species. Hence this is probably the second record of the species from Sri Lanka.

Another ‘Lost Bird’ found

Fiji Petrel Pseudobulweria macgillivrayi was known from just one specimen collected in 1855 on Gau Island, Fiji, and was lost for the next 130 years. Since 1984 there have been a handful of reports of “grounded” birds that had crashed onto village roofs on Gau. Until now there had been no confirmed sightings of this mysterious seabird at sea.

An expedition to find the Critically Endangered Fiji Petrel at sea, was conducted by a team of researchers recently. The expedition was partially financed by a grant from the BirdLife Preventing Extinctions Programme and its official sponsor, the British Birdwatching Fair. The expedition has been successful, returning with stunning images and new information on one of the world’s least-known seabirds.

The search for the elusive petrel is described in a paper in the latest Bulletin of the British Ornithologists' Club. Up to eight individuals were seen over eleven days in an area around 25 nautical miles south of Gau. The species’ flight, behaviour and detailed comparison to other species are also described for the first time.

An observation of Jungle Crows feeding on a Brown-headed Barbet

Crows are well known for their opportunistic habits. They are recorded as mobbing, killing juveniles, weaker birds, and adults of several other bird species. Crows are also known to feed on eggs and chicks in the nest.

Following observation was made in a moderately wooded suburban area in Piliyandala. On 24 June 2009 at around 10am, I observed a pair of Jungle Crows (Corvus levaillantii) perched on the branch of a mango tree feed on an unidentified object of moderate size. One of the crows was holding it by a leg and both birds were seen feeding on it. A few moments later, the object was dropped to the ground. When examined, it was clear that it was the skull of a Brown-headed Barbet (Megalaima zeylanica). The whiskers and bare facial skin were intact whereas the rest of the fleshy parts were absent. It was not difficult to recognise that the bird had been recently killed. The appearance of the beak and other parts suggested that the barbet was an adult. The surroundings were searched for any other remnants of the dead bird, but without success. Two other jungle crows were present in the vicinity at the time.

It is not clear whether the crows killed the barbet or if it was scavenged as carrion. Based on the condition of the skull, the barbet was probably a healthy individual; therefore accidental death while possible, is unlikely. Predatory attacks on the barbet cannot be ruled out although no predatory bird or mammal was observed in the vicinity.

Sex determining gene found in Birds

Australian scientists have discovered the gene that makes birds male.

The discovery of the sex determining gene in birds, published in a recent edition of ‘Nature’, could help scientists understand sex disorders in humans.

Geneticist and author Professor Andrew Sinclair, of the Murdoch Children's Research Institute and the University of Melbourne, says locating the gene, known as DMRT1, is an enormous breakthrough that has eluded scientists for more than a decade.

In 1990, Sinclair was involved in discovering the mammalian sex determining gene SRY. But the same mechanism in birds has not been well understood.

Like humans birds have two sex chromosomes, except males carry two Z chromosomes while females carry one Z and one W chromosome, says Sinclair.

Sinclair says DMRT1 is found on the Z chromosome. He says they long suspected that DMRT1 played a role in sex determination because of its similar function in other animals, including humans.

New bird species discovered in Asia

An odd looking songbird with a bald head living in a rugged region in Laos has been discovered by scientists from the Wildlife Conservation Society (WCS) and the University of Melbourne, as part of a project funded and managed by the mining company MMG (Minerals and Metals Group).

The species has been named Bare-faced Bulbul Pycnonotus hualon because of the lack of feathers on its face and part of its head. It is the only example of a bald songbird in mainland Asia. It is the first new species of bulbul – a family of about 130 species – described in Asia in over 100 years. A description of the new species has been published in the July issue of Forktail, the journal of the Oriental Bird Club.

The thrush-sized bird is greenish-olive with a light-colored breast, a distinctive featherless, pink face with bluish skin around the eye extending to the bill and a narrow line of hair-like feathers down the centre of the crown.

The bird seems to be primarily tree-dwelling and was found in an area of sparse forest on rugged limestone karsts – a little-visited habitat known for unusual wildlife discoveries.

"Its apparent restriction to rather inhospitable habitat helps to explain why such an extraordinary bird with conspicuous habits and a distinctive call has remained unnoticed for so long", said Iain Woxvold of the University of Melbourne and lead author of the paper.

Fortunately much of the bird's presumed habitat falls within legally protected areas in Laos. However, quarrying of limestone looms as a potential threat to wildlife in this area, along with habitat conversion for agriculture.

Capturing birds during the non-migratory period 2009

FOGSL Bird Ringing team conducted a short bird ringing session at Bundala National Park from 25th to 28th June 2009 in collaboration of the Department of Wildlife Conservation. This session was conducted to capture birds at the non-migratory period.

Bird ringing at the non-migratory period is not exciting as at the migratory period where large number of birds and species captured. Although it is expected to have very low number of migrant birds in the area, there were fairly good number of birds which can be considered as stragglers and resident group of Kentish plovers. However, 12 bird species including four wader species were captured during the session. A common redshank which was first ringed during the ringing session in December 2008 was recaptured.
Prof. S.W. Kotagama, Mr. C.D. Kaluthota, Mr. R.A.R. Perera, Mr. Kasun Dayananda and Mr. Pradeep Suranga participated in this session. Five officers of the Department of Wildlife Conservation also participated in the ringing session as trainees. FOGSL acknowledges all the participants for their difficult task in the field, Mr. W.A.A.D.U. Indrajith (Park Warden, Bundala NP) and his staff for their role to facilitate this session in the Bundala National Park.
