Tyrant
Birds and African Bats up to the Basking Shark and the Short-Beaked
Dolphin Given Conservation Boost
Governments Also Call for Knowledge Gaps on Avian Flu and
Wild Birds to be Bridged Nairobi/Bonn,
25 November 2005 - A wide range of curious and charismatic
animals have today been given a big conservation boost
at the end of an international wildlife meeting being
held in the Kenyan capital Nairobi.
They include the Mediterranean population of the Short-beaked
common dolphin; Henderson’s petrel; the Basra reed warbler;
the Large-eared free-tailed bat or Giant mastiff bat;
the Strange-tailed tyrant; the Basking Shark and the Saffron-cowled
blackbird.
The decisions were taken at the close of the eight conference
of the parties to the United Nations Environment Programme’s
Convention on Migratory Species (UNEP/CMS).
Governments and delegates also backed a seven point plan
to improve knowledge and understanding of avian flu as
it relates to wild migratory birds.
Earlier in the week it was announced that the CMS in collaboration
with others and with support from UNEP would be establishing
an ‘early warning system’ for avian flu.
The system is aimed at giving, especially for developing
countries, improved information including maps on the
migration routes of wild waterbirds.
Today’s end of conference decision calls for close collaboration
between scientists, conservationists, agriculturalists,
veterinarians and public health experts to unravel key
mysteries.
These include the length of time the virus can survive
in wetland habitats up to the question of whether infected
birds are even capable of migrating.
Ward Hagemeijer of Wetlands International and a member
of the Scientific Task Force on Avian Influenza, said:
“Better biosecurity in the rearing, movement and trade
in poultry and captive birds remains the key concern.
Although recent cases seem to suggest that migratory wild
birds are somehow involved in spreading the virus over
large distances, so far there is no solid evidence that
they are significant vectors”.
“However we do know that they are victims and that this
disease can pose a threat to populations already under
pressure. We need urgent research into what the role of
wild birds might be now and in the future, in order to
be able to contribute to and complement the important
work that the World Health Organization, the Food and
Agriculture Organisation of the UN and the World Organisation
for Animal Health are doing,” he added.
John O’Sullivan of BirdLife International and another
member of the Task Force, added: “A good understanding
of the routes, patterns and timing of migration is vital
not only for disease control but also for conservation.
The role of wild birds in the present outbreak of highly
pathogenic avian flu is far from clear, and may be minimal.
A better global monitoring system is badly needed to help
assess the risk of future outbreaks that could impact
migratory birds, or be carried by them and to deal effectively
with any cases that occur.”
Other important decision concluded this week include the
budget for the CMS to finance its work over the coming
years, new agreements or Memorandums of Understanding
between countries on West Africa’s elephants and the Saiga
antelope of Central Asia aimed at catalyzing cross border
conservation cooperation.
By-catch, in which animals like dolphins become entangled
in fish nets, has also been addressed with the CMS to
build cooperative bridges between the convention and regional
fisheries bodies in order to reduce the problem.
An initiative on the conservation of migratory birds of
prey and owls found in Africa and Eurasia led by the Government
of the United Kingdom was also given backing.
Studies presented to the conference indicate that 60 per
cent of these birds, which include vultures, eagles and
kites, are threatened with extinction as a result of issues
such as shooting, and deliberate or accidental poisoning.
Today the UK announced it was giving 100,000 British Pounds
towards a meeting where governments will meet to thrash
out the next steps towards better conservation.
A delighted Robert Hepworth, Executive Secretary of the
CMS, said: “Governments, scientists and our partner bodies,
such as the World Conservation Union, have demonstrated
their commitment to CMS this week. Hundreds of threatened
species throughout the world all gain from the scientific
and practical support we can now offer, especially in
developing countries over the next three years. This was
my first Conference as the Executive Secretary, I believe
we are now properly on “the move to 2010.”
Klaus Toepfer, UNEP’s Executive Director added: “If we
are to meet the targets and timetable of the 2002 World
Summit on Sustainable Development, which call for the
rate of loss of biodiversity to be reduced by 2010, we
must conserve wildlife both within and across borders.
This week’s conference is proof positive that this is
increasingly understood by the global community”.
New Listings
Species under the convention are listed as Appendix I
or Appendix II.
Those given the former are endangered species. Measures
that should be undertaken by relevant governments include
improving habitats and breeding sites and removing obstacles
to their migration.
The latter listing calls on nations to establish regional
agreements, such as memorandums of understanding, to conserve
the species. (see notes to editors for full explanation).
Birds
Several species of birds have been given listings and
additional protection at this week’s conference.
Henderson’s Petrel is a sea bird known to breed only on
Henderson island in the UK Overseas Territory of Pitcairn.
It has been given Appendix I status.
The bird is threatened by rats and possibly predation
by crabs. Breeding success is low with less than 20 per
cent of eggs yielding fledglings.
The listing is expected to lead to closer cooperation
between France and UK. A similar-looking bird is also
found on other islands in the region which are part of
French Polynesia which may prove to be the same species.
Joint measures may include rat eradication on the islands
concerned.
The Madagascar Squacco Heron or Malagasy Pond-heron, which
migrates between Madagascar and countries like the Deomcratic
Republic of Congo, Kenya and Uganda, has been given Appendix
I listing.
Its population is down to between 2,000 and 6,000 birds.
It is threatened by habitat degradation and exploitation
of eggs and young at breeding grounds.
The Red Knot, a bird which migrates between places like
Southampton Island, Canada, and Tierra del Fuego and Argentine
Patagonia in Latin America, has been included on Appendix
I.
Habitat destruction as a result of tourism and unplanned
developments is a key threat. Drastic reductions in population
have been recorded at core sites in Tierra del Fuego.
It has disappeared from wintering areas in Patagonia.
The Basra Reed Warbler has also been added to Appendix
I. The population is believed to be declining and is down
to between 2,500 and 10,000 individuals.
The species breeds in places like the Mesopotamian marshlands
of Iraq, an area that was heavily drained under the previous
Iraqi regime. The warbler migrates to countries including
south east Kenya, Sudan, south Somalia, east Tanzania
and Mozambique.
At the Ngulia ringing station in Kenya, studies indicate
that the birds numbers may have fallen by between 70 per
cent and 80 per cent since the 1970s.
The Balearic Sheerwater, a seabird whose world breeding
population is around 2,000 pairs, has been included in
Appendix I. It breeds on Spanish islands like Mallorca,
Ibiza and Formentera in caves and cavities in coastal
cliffs.
The species migrates towards the Gulf of Biscay with some
birds traveling to North African waters and as far as
southern Scandinavia and South Africa.
Threats include predation by introduced cats, rats and
small-spotted genets and, while at sea, pollution.
The Spotted Ground Thrush, whose population is estimated
at just 1,000 to 2,500 individuals, has also been given
Appendix I listing. Two migratory races are known to exist.
One that moves between places like the Arabuko-Sokoke
forest in Kenya and Tanzania, possibly Mozambique.
Another in South Africa that migrates between places like
Natal and Transkei and the Transvaal.
Habitat destruction of its forest homes is the main threat.
The bird is a night migrant and may be affected by collisions
with lighted buildings.
Birds which have been given Appendix II listing include
the Rock Pratincole, a bird of possibly some 25,000 individuals
that migrates across west and central Africa that is threatened
by issues like sand mining on rivers; the African Skimmer,
found in west and central Africa and east and southern
Africa which is threatened by human and cattle disturbance;
the Strange-tailed Tyrant, occurring in Paraguay and northern
Argentina that is believed to have suffered catastrophic
losses in Brazil.
Others are the Cock-tailed Tyrant, found across a wide
range including north and east Bolivia, southern Brazil,
eastern Paraguay and northern Argentina whose tall grassland
habitat is threatened by agricultural development; the
Chestnut Seedeater, another south American bird; the Gray
and Chestnut Seedeater; the Marsh Seedeater and Saffron-cowled
blackbird found in south eastern Paraguay, Argentina and
Uruguay. Its population is believed to have declined by
over 30 per cent in the past decade.
Mammals
Several mammals have been listed today including the Mediterranean
population of the short-beaked common dolphin which has
been placed on Appendix I and Appendix II.
Its migration patterns are not well understood but animals
are thought to move across the Gibraltar Straits and possibly
through the Turkish Straits system.
Precise numbers are also unknown but it is believed that
number are declining as a result of impacts such as by-catch
in fishing nets.
The Bukhara Deer, central Asia’s only true deer inhabiting
the regions’s arid zones, has also been added to Appendix
I and Appendix II. It migrates across the borders of countries
including, Tajikistan and Uzbekistan.
The population was estimated to be as low as 350 animals
in 1995. Targeted conservation by groups like the World
Wide Fund for Nature have brought numbers up to 800 to
900.
Poaching on migrations is the key threat with others including
habitat destruction and possibly pesticide contamination
from cotton fields.
Gorillas have also been out on Appendix I. These include
the eastern lowland, western lowland and mountain gorillas.
The animals are threatened by issues such as habitat degradation
and killing for bushmeat along with civil wars and unrest.
The Basking Shark, the world’s second largest shark which
grows up to 10 metres in length, has also secured Appendix
I and II listing. This giant filter feeder is found in
areas such as the continental shelves of the Atlantic
and Indo-Pacific oceans and the Mediterranean Sea.
The global population is unknown but it is thought that
between 80,000 and 106,000 animals have been taken from
the whole of the north east Atlantic in the past half
century.
The animals are believed to highly migratory. A recent
tagging study by the UK government found that the basking
sharks moved around the north east Atlantic into waters
off France, Ireland, England and Wales and northwards
into Scottish waters.
Basking sharks in American waters are now know to migrate
into Canadian and Caribbean waters.
Threats centre on by-catch and direct catches of the animals.
Because they often congregate in bays and shallow waters,
they are also at risk from collisions with vessels. Indeed
collisions may be frequent as scarring is often seen on
these sharks.
Global warming, affecting their food source of plankton,
may be an emerging threat.
The African populations of three species of bat have also
been listed under Appendix II.
The Natal Clinging bat or Schreiber’s bent-winged bat
is found in countries including the Democratic Republic
of Congo and South Africa. The bats migrate seasonally
and are threatened by habitat degradation as result of
agricultural development, mining and tourism. Migration
routes can be affected by war and bats are sometimes killed
for food and other uses including the exploitation of
acoustic membranes for making drums.
Also added to Appendix II is the Large-eared free-tailed
bat or giant mastiff bat. It is widely distributed between
eastern Africa from Ethiopia to South Africa. Colonies
may number a few dozen, such as in houses in South Africa,
up to several hundred. Two lava tube sites in Kenya--
at Mount Suswa in the Rift Valley and at Ithundu in the
Chyulu Hills—have been recorded with more than a 1,000
bats.
Recent surveys there have found that the bats have all
but disappeared with only 17 found at Ithundu.
There is no direct evidence of migration but suspicions
that some may migrate between Kenya and Tanzania.
Threats include disturbance and changes to the microclimate
of lava tube sites as a result of, for example, guano
digging, tourism and the blocking of entrances.
The third bat listed under Appendix II is the Straw-coloured
fruit bat. It is widespread across Africa including on
the Gulf of Guinea islands and Zanzibar, Pemba and Mafia
off Tanzania.
A colony in Kampala was estimated in the 1960s to number
about one million. But numbers have declined and the animals
are treated as a nuisance leading to the removal of roosting
trees and poisoning programmes. The same situation has
occurred in Lome, Togo.
Notes to Editors
Documents relating to the Eighth Conference of the Parties
to the Convention on the Conservation of Migratory Species
of Wild Animals (CMS) can be found at www.cms.int
CMS is an intergovernmental treaty concluded under the
aegis of the United Nations Environment Programme (UNEP.
Migratory species threatened with extinction are listed
on Appendix I of the Convention. CMS Parties strive towards
strictly protecting these animals, conserving or restoring
the places where they live, mitigating obstacles to migration
and controlling other factors that might endanger them.
Besides establishing obligations for each State joining
the Convention, CMS promotes concerted action among the
Range States of many of these species.
Migratory species that need or would significantly benefit
from international co-operation are listed in Appendix
II of the Convention. For this reason, the Convention
encourages the Range States to conclude global or regional
Agreements.
In this respect, CMS acts as a framework Convention. The
Agreements may range from legally binding treaties (called
Agreements) to less formal instruments, such as Memoranda
of Understanding, and can be adapted to the requirements
of particular regions. The development of models tailored
according to the conservation needs throughout the migratory
range is a unique capacity to CMS.
