Scientific Ringing

Scientific Ringing

Onaga carries out campaigns of scientific ringing to various ends:

  • Study the dynamics of a population under consideration
  • Migration
  • Inventory of a given species
  • Environmental Education

A great part of our current knowledge of the migratory patterns of birds is due directly to scientific ringing. Until a little more than a century ago nothing whatsoever was know about the seasonal disappearance and reappearance of birds in given regions. The first steps toward a resolution of these questions came with the birth of ringing. This involves the individual marking of birds which can be identified upon recapture in order to know the route they have taken.

Many methods are used to catch the birds each particular to the birds we wish to study. Never the less the most widely used method is the Japanese nets which are perfect for smaller and médium sized birds (principally passerines).

This marking consists of putting a small ring on the birds leg. The ring is engraved with a number and contact information so that the person who recaptured the bird can send on the information.

In order to control the whereabouts of these birds at a distance without the need to recapture them by hand, they can also be fitted with other systems such as rings that can be read at a distance, color combinations, wing markers, collars or nasal plaques among others.

Scientific ringing is yet another tool used to compile a comprehensive study of the demography, longevity and use of habitat of birds which leads us not only to a comprehensive understanding of their biology but also offers an opportunity to reach out to the public through education and awareness.
