FOGSL checklist on BUBO Listing

BUBO Listing is a new approach to an old activity; comparing birding lists. Whilst frowned upon by the more serious-minded, bird listing is as vibrant, active and exciting as ever. Put two birders in a room together and before too long they'll know if the other saw the 2006 Long-billed Murrelet in Devon!

BUBO Listing is an attempt to provide a free, flexible and widely used site for the comparison of birding lists. The more people that use BUBO Listing, the better it will become for all users.

BUBO Listing is an online database similar to ‘Sri Lanka Birds’ which is familiar to Sri Lankan bird watchers. BUBO Listing provides facilities to record bird lists across the globe, simply for any country.

BUBO Listing recently accepted FOGSL checklist (Revised avifaunal list of Sri Lanka) as the official checklist for Sri Lanka.

Field Workshop at Belihul Oya

The field workshop at Belihul Oya was held from 27th to 30th of May 2010. Our campsite was an abandoned school in Kumbalgama which was a few kilometres away from the Sabaragamuwa University.

We were given a few brief lectures at the Colombo University by Professor Sarath Kotagama as an introduction to the workshop. After leaving the Colombo University at about 10.00h we reached the camp site around 15.30h. Lunch was eaten at a roadside boutique.
Upon arriving at the campsite we were given the chance to introduce ourselves. We were then divided into four groups. Each of these groups had four members and was named after a particular bird group. Each of the four members had to learn about one of the birds in the group of birds chosen.

The rest of the day was spent getting to know the trails and doing some birding in the grasslands and the forested areas. Birds like Chestnut-headed Bee-eater, Spotted Dove, Malabar-pied Hornbill, Lorikeet, Coppersmith Barbet were observed. After dinner we were given a lecture by Chinthaka on counting methods.

The next morning we did transects of which the main objective was counting how many birds found in an area. Three 200m paths were marked and all the bird species and numbers were taken down.

After breakfast we set up mist nets in order to capture a few birds. Two Dark-fronted Babblers were captured, processed and released. Here we were taught how to handle the birds and how to fill the data sheets. The basic grip also called the ringers grip was taught and each of us had the opportunity to handle the birds. The evening was spent doing point counts. Here, five circles within a radius of 25m were marked and group members observed and noted down birds seen at a 360 degree angle from the centre of each circle. A graph was also drawn to show how many new bird species were seen in each circle.

At night we were given a very interesting lecture on animal behaviour. Here, four behaviour study methods were stressed upon, them being Ad libitum method, one-zero method, focal animal method and scan sampling method. Here two groups chose White-rumped Shama and the other two chose the White-browed Fantail and we were study on each of these birds the next day. After this we were shown a small presentation on bird ringing and tracking. It was amazing to see how technology has developed and how you can track a bird anywhere in the world using satellite transmitters.

On the third day nets were set up early morning once again. The nets were monitored every half an hour. Here an Oriental White-eye and three Tawny-bellied Babblers were captured and processed. The hungry netters were treated with vadai and tea by a kind-hearted lady who lived close by.

After arriving back at camp and having breakfast the groups had a small opportunity to take a deserved break which we made the most of.

By noon we were up and ready to track down Shamas and Fantails in order to do our behaviour study. This was a very rewarding experience as it wasn’t easy! At first we didn’t get a chance to observe the Shama for even five minutes but as it got used to us it settled down for extended periods and we were able to sit on the ground and study it for long periods. It was an amazing experience sharing space with this beautiful bird. Our group also managed to mark the territory of this particular Shama. This was done by crawling through the bushes and following the Shama at every possible moment.

By lunch time we were very tired and took a small break after lunch. By about 15.00h we were up once again to study the Shama. Here we were very lucky indeed as we saw two female Shamas attacking each other possibly over territory. As we crawled through the bushes following the Shama we found a new pathway leading to the grasslands we had explored on the first day. At one point the Shama was within touching distance of the group.

After everyone arrived at camp each of the group members described the bird chosen by them on the first day, to an eager audience. After this an ethogram was formed on the screen based on the behaviour we saw studying the Shama. Many groups stayed up well into the night in order to finish their group reports.

On the last morning we managed to put in about 45 minutes of birding in between the rush of writing group and individual reports. After breakfast we discussed the events which we did during this workshop and soon after it was time to pack our tents and bags to head back to Colombo.

It was hard to say goodbye to all the new friends we had got to know and meet during our trip to Belihul Oya. I would like to thank all the senior members at the Field Ornithology Group of Sri Lanka for making this workshop possible in such a short space of time, as the workshop which was to be held at Buttala could not take place due to unavoidable circumstances.

All in all this was a great learning experience for me and I only hope to improve my skills in the future. I am looking forward to the many other workshops including the one at Sinharaja which I am sure will be another wonderful experience just like this.

Another bird species joined with Dodo

BirdLife International has announced, in the 2010 IUCN Red List update for birds, the extinction of Alaotra Grebe Tachybaptus rufolavatus. Restricted to a tiny area of east Madagascar, this species declined rapidly after carnivorous fish were introduced to the lakes in which it lived. This, along with the use of nylon gill-nets by fisherman which caught and drowned birds, has driven this species into the abyss. Alaotra Grebe will have been unknown to most people but, like a great painter whose work is recognised only after they have died, it will now become better known because of its extinction.

"No hope now remains for this species. It is another example of how human actions can have unforeseen consequences", said Dr Leon Bennun, BirdLife International's Director of Science, Policy and Information. "Invasive alien species have caused extinctions around the globe and remain one of the major threats to birds and other biodiversity."

And it's not just aliens. Wetlands the world over, and the species found in them, are under increasing pressures.

"Wetlands are fragile environments, easily disturbed or polluted, but essential not only for birds and other biodiversity but also for millions of people around the world as a source of water and food", said Dr Stuart Butchart, BirdLife's Global Research and Indicators Coordinator.

According to the latest revision of the Red list for birds by BirdLife International, a total of 1240 bird species are threatened. This is an increase of 14 species compared to the number in 2009 analysis. Numbers of threatened species in each category are as follows.

Extinct - 132
Extinct in the Wild - 4
Critically Endangered (incl. Possibly Extinct) - 190 (14)
Endangered - 372
Vulnerable - 678

'Bird populations are declining' - Global Biodiversity Outlook 3

“The target agreed by the world’s Governments in 2002, “to achieve by 2010 a significant reduction of the current rate of biodiversity loss at the global, regional and national level as a contribution to poverty alleviation and to the benefit of all life on Earth”, has not been met.”

“The action taken over the next decade or two, and the direction charted under the Convention on Biological Diversity, will determine whether the relatively stable environmental conditions on which human civilization has depended for the past 10,000 years will continue beyond this century. If we fail to use this opportunity, many ecosystems on the planet will move into new, unprecedented states in which the capacity to provide for the needs of present and future generations is highly uncertain.”

These excerpts are from the latest version of Global Biodiversity Outlook launched on 10 May 2010.

Global Biodiversity Outlook is the flagship publication of the Convention on Biological Diversity. Drawing on a range of information sources, including National Reports, biodiversity indicators information, scientific literature, and a study assessing biodiversity scenarios for the future, the third edition of Global Biodiversity Outlook (GBO-3) summarizes the latest data on status and trends of biodiversity and draws conclusions for the future strategy of the Convention.

Some facts on Bird populations from GBO-3

· Farmland bird populations in Europe have declined by on average 50% since 1980.
· Bird populations in North American grasslands declined by nearly 40% between 1968 and 2003, showing a slight recovery over the past five years; those in North American drylands have declined by nearly 30% since the late 1960s.
· Of the 1,200 waterbird populations with known trends, 44% are in decline.
· 42% of all amphibian species and 40% of bird species are declining in population.
· Bird species have faced an especially steep increase in extinction risk in South-East Asia, on the Pacific Islands, polar regions and in marine and coastal ecosystems.

World Environment Day (WED) - 5th June 2010

World Environment Day (WED) 2010 is aimed to be the biggest, most widely celebrated, global day for positive, environmental action.

Commemorated on 5 June since 1972, WED is one of the principal vehicles through which the UN stimulates worldwide awareness of the environment and encourages political attention and action.

Through WED, we are able to give a human face to environmental issues and enable people to realize not only their responsibility, but also their power to become agents for change in support of sustainable and equitable development.

WED is also a day for advocating partnerships among all stakeholders or perhaps, even more correctly, among all species living on this one planet and sharing a common future.

WED 2010 is aimed to be the biggest WED celebration ever and we count on you to make this happen! We call for action – organize a neighborhood clean-up, stop using plastic bags and get your community to do the same, plant a tree or better yet organize a collective tree planting effort, walk to work, start a recycling drive . . . the possibilities are endless.

The theme of WED 2010 is “Many Species. One Planet. One Future.” It echoes the urgent call to conserve the diversity of life on our planet. A world without biodiversity is a very bleak prospect. Millions of people and millions of species all share the same planet, and only together can we enjoy a safer and more prosperous future.
