The ringing system controlled and supervised by the avicultural societies is not fit for
purpose. The scheme makes verification difficult for investigating authorities, because
there are no standard requirements for the rings and there is no central, digital
database to access in order to quickly verify a ring.

The ringing system
In 2004, the AID investigated whether or not the number of leg rings applied for by
various avicultural societies corresponded with the actual number of birds kept or
bred by bird keepers (AID annual report 2004). This AID-investigation concluded that
there were more applications for leg rings than there were birds being bred.
It is easy to obtain leg rings by applying to avicultural societies – this does not require
membership. During investigations for this report, a case came to light of a bird
keeper who allegedly kept only a few birds but who applied for 1000 leg rings.
The ring commissioner decided this was too much, but instead of sizing up the situation
himself, or informing the authorities, he decided to issue 350 instead of 1000 leg
rings. The bird keeper subsequently obtained two additional sets of 350 leg rings by
means of friends at other societies.
The issuing, supervision and administration of rings is in the hands of avicultural
societies. There is no independent supervision of the system nor is there any prospect
of this. The defective organization of the ringing system, combined with its supervision
almost entirely by bird keepers, is bound to give rise to illegal trade.
Avicultural societies also make money by selling leg rings, as Aviornis reports in its
periodical (February 2006):
“Remember that by ordering your rings at Aviornis, you support our
organization and indirectly yourself! So order now, if you have not done
so already!”
This means that there is an undesirable conflict of interests, as strict supervision of
the issuing of rings by a society could lead to a decrease in income for that society and
a loss of membership. In addition, a decision to refuse rings to someone will, in most
cases, have no effect, because inevitably another society will issue them.
As described in Section 2.3 and below, adult birds are ringed as well as chicks, so the
assumption on which the policy is based, namely that closed leg rings can only be
fitted to the legs of young birds is false.
Vogelbescherming Vlaanderen has made a detailed description (May 2003) of the
methods of putting rings on wild-caught birds.
Several Dutch experts in the tracking of illegal trade in European birds have, in the
light of this investigation, stated that the situation in the Netherlands is not fundamentally
different than the one in Belgium.
The following techniques are discerned in the above-mentioned report:
• Sawing through rings, putting them on and bending them back. Sometimes the
ring is reworked with a soldering iron, super glue, or felt-tip pen to cover up the
saw-cut.
• Increasing the inner diameter of the ring by removing the material, for instance
with a file, or by drilling.
• Increasing the inner diameter of the ring without removing the material, for
instance with a hammer and a nail, or a punch which is normally used for making
additional holes in a belt. Sometimes the ring is squeezed shut with a pair of pliers
afterwards.
• Using leg rings that are too big.
The ringing of wild birds with a closed ring is no gentle business. During confiscations
and also at markets and exhibitions, birds with leg injuries are encountered on a regular
basis. A lot of force is used to put a (more or less) tightly fitting ring on an adult
bird. This regularly leads to accidents and even deaths during the ringing process.
There are professional ringers active and more often than not they are not bird
keepers. In Belgium, arrests have been made of dealers that were in the possession of
thousands of rings (applied for and issued by avicultural societies) and many unringed
birds.
The following AID press release of 3 February 2006 shows a Dutch example:
“The General Inspection Service (AID) of the Dutch Ministry of
Agriculture, Nature and Food Quality has confiscated 61 protected
species of native birds at a bird keeper in the province of Groningen. It
was established that of the 76 birds that were present, 61 wore rings that
had been tampered with. A major part of the birds were ringed with
damaged rings or rings that were too big. It is therefore suspected that
A broken leg as result of ringing an adult bird
these birds have been wild-caught and provided with leg rings at a later
moment to suggest captive breeding. It is only legal to put seamless
closed rings on young captive-bred birds. These leg rings are provided by
Dutch avicultural societies. A report has been made of this offence
against Flora and Fauna Legislation.”
Most confiscations concern song birds, but sources within the police and the cage-bird
scene mention that there are also ducks,waders, raptors and owls being caught in the
wild and subsequently ringed. Species mentioned include sparrowhawk and hobby.
During this investigation no hard evidence was found to support the claim that raptors
are ringed at the nest site, left there to be raised by the parent birds, and robbed
just before they are about to leave the nest. TheWorking Group on Birds of Prey in the
Netherlands checks thousands of nests a year and has never found ringed young.
Young raptors are, however, robbed and raised by hand (see 2.3).

اخي الكريم شكرا على الرد
ولكن
كيف جزمت بالكلام اكيد 100% الدليل لو تكرمت
احب افيدك اننا هنا اكثر من 2 ومختلفين ونخالف كلامك بنفس الوقت
ثانيا مافيه شي اسمه فحص ليزر
يمكن تقصد المنظار؟؟ وهذا مايعمل الا للطيور الكبيره للكشف على الاجهزه التناسلية
علما ان خطورتة كبيره على الطير ولايستخدم كثيرا
اكرر كلامي الله يرحم والديكم مانبي أرائكم الشخصية نبي دليل موثق او مرجع علمي مع احترامي للجميع
اخوي احترم هدفك من الموضوع و اسمحلي ما قلتلك من وين جبت الكلام
مصدر الكلام من واحد عنده مزرعه و اكثر من محل للحيوان و انا سالته وهوه عميل عند المزارع الهولنديه و قالي هذا الكلام
بخصوص الفحص هوه قالي صلب في ليز و يخشونه في فتحت الشرج اكرمكك الله
وانا اعرف فحص المنضار لا هب هوه

مرحبا بك اخوي وشكرا على تفاعلك مع الموضوع
ولكن
اخوي انت خلطت موضوعين مع بعض وليس لهم دخل في موضوعنا الاصلي
الكلام الاول يتكلم عن الحجول المفتوحة التي تستخدم بعد تحليل جنس الطير من قبل المختبرات
وهي مايستخدمه المربين للتفريق بين جنس طيورهم او في المحاجر الصحية للفحص او للابحاث من قبل الجمعيات العلمية (كلامنا عن الحجول الصك المختومه التي توضع للفروخ)
الكلام الثاني (والله يسامحك خليتني اقرا 44 صفحه)
الباحث يتكلم عن الصيد الغير شرعي
التجارة الغير شرعية في اوربا
طرق التحايل على نظام الحجول
وغير ذلك من امور بعيده عن موضوعنا الاصلي
ويذكر توصيات في اخر البحث عن مواصفات الحجول المطلوبة وعن ضرورة انشاء قاعدة بيانات
