Bird Ringing اسواق الفوركس


Ringing aims to understand what is happening to birds in the places they live and how this affects population increases and decreases, this knowledge is vital for conservation. It also gives information on the movements individual birds make and how long many live for. You can help by looking out for ringed birds and reporting them.


1 السوق المالي السعودية تداول Recording the correct data as per required standard.

Ringing birds is essential if we are to learn about how long they live and when and where they move, questions that are vital for bird conservation. Placing a lightweight, uniquely numbered, metal ring around a bird’s leg provides a reliable and harmless method of identifying birds as individuals.

The Bird Ringing Scheme in South Africa was initiated in 1948, so 1998 saw the 50th anniversary of the scheme. During this period over 1.7 million birds of 852 species were ringed. There have been a total of 16 800 ring recoveries since the inception of the scheme. This gives an overall recovery rate for rings in southern Africa of marginally less than 1%, averaged across all species. This probability varies enormously across species.

The traditional objective of SAFRING is to establish a database of recoveries of southern African birds that can be used to establish information about movement and survival. Every bird ringed, no matter what species or where it was ringed has the potential to contribute to the SAFRING recovery database. Since 1982, this database has been supplemented by a retrap database, supplied by ringers on a voluntary basis. Although we have been ringing birds in South Africa for more than 60 years, we are still discovering new facts about migration routes and wintering areas. However, the main focus of the Ringing Scheme today is monitoring bird populations. Ringing allows us to study how many young birds leave the nest and survive to become adults, as well as how many adults survive the stresses of breeding, migration and severe weather. Changes in survival rates and other aspects of birds’ biology help us to understand the causes of population declines.

The database as a whole is a resource which may be used by researchers, conservation biologists and managers, and primarily provides answers to questions related to movement and survival. Research into bird populations of importance to fisheries, agriculture, conservation and water management authorities involves bird ringing. Ringing provides a cost- effective tool for monitoring our environment and commonly draws attention to pollution, poisoning, powerline incidents, longline fishing fatalities and other hazards.

There are currently 130 active ringers operating in South Africa and neighbouring countries such as Namibia, Botswana, Zimbabwe, Zambia and Malawi. About 70 000 birds are ringed annually. Ringers, both amateur and professional, have to pay for all rings used. An exception are those rings used on Redbilled Quelea, which are paid for by the Department of Agriculture. Recoveries of ringed quelea provide data on movements and mortality and contribute to a better understanding of the population dynamics of this explosive species.

Bird ringers come in many guises, from individuals working in urban areas, to large groups working in a wide geographic area, with ages ranging from under 10 to over 80. So depending where you are, when you have qualified, you could get involved with ringing seabirds, owl chicks in nest boxes, catch a huge variety of passage migrants on the coast, monitor garden birds at home or be fortunate to ring raptors!



بيع اسهم الاكتتاب As with all hobbies there are certain risks!


Most ringers catch birds when they’re at their most active, which is often early in the morning, so sessions starting at, or before, 04:00 are commonplace - and ringing sites are rarely accesible by public transport. A good morning’s ringing may take you through to lunchtime, but there’s always the possibility of catching birds coming to roost or even catching at night. You’ll no doubt find that ringing is a very satisfying activity. Not only will you be adding to over 60 years of data used directly by conservationists, but enjoying the experience of seeing birds close up, your contribution is vital.

The ringing process involves much more than you might imagine, preparation and planning to catch and ring birds is essential. Habitat management at ringing sites, maintenance of equipment and stocking winter feeding stations are all essential jobs. Most trainers and groups share chores with everyone getting involved. There is a lot to do and it will take up a lot of time. سوق الاسهم السعوديه اليوم REQUIREMENTS FOR BIRD RINGERS


An aspirant bird ringer’s ability to operate independently needs to be assessed by the ringers responsible for the candidate’s training, who will ultimately recommend the trainee for an AA-permit. To this end, essential areas of proficiency have been identified as being the minimum standards to be achieved by the trainee.

A ringer must be competent to operate the equipment used to capture birds in a safe way. This includes the planning, siting, handling and monitoring of nets and traps in different situations.

A ringer must be able to capture and handle birds and store them, and fit rings to wild birds, without causing undue stress or injury to the birds.

A ringer must have a high level of competence in bird identification of the birds in the hand. A ringer shall not normally ring any bird that cannot be positively identified.

A ringer must be able to undertake accurate, repeatable standard anatomical measurements.

A ringer must be able to record information accurately, understand and conform to the administrative procedures of SAFRING, submit schedules in good time and store data in the long term.



تداول الأسهم السعودية Accurate measurements of the wing taken.


Permits to ring birds should be issued on the recommendation of SAFRING, which in turn will act on the advice of experienced ringers.

The development of the above-mentioned areas of proficiency and competency is partly linked to the numbers of birds and species processed. Your trainer will inform you of the requirements and while the preceding standards are very important, the ringing trainer will also assess the trainee’s feeling or passion for birds entrusted to his care as well as the trainee’s attitude to bird ringing.
