IDENTIFYING JAGUARS

Being able to differentiate one jaguar from another makes it possible to identify them as individuals, estimate their numbers, track their movements over time and monitor their health condition.
Several techniques can be used:

Spots recognition:Comparison of the spots arrangements and shapes which are specific to the coat of each jaguar.

Life marks recognition: Broken tail, cut ear, missing limb, punctured eye, scar, handicap, specific coloration, etc.

Genetic recognition: Feces and hair collection in the field as well as blood or saliva analysis when an individual is captured.

ROSETTES: A jaguar's UNIQUE ID PATTERN

Recognition by spots (called rosettes) is the most used identification method since it can be put in application for individuals without life marks and does not require direct contact with the animal. Take the example of Shāhdosa, an adult male who has never been captured and has no particular life marks, whose tracking was possible thanks to the recognition of his spots. One of them, shaped like an "S", located on its right flank, is easily identifiable. It is important to specify that the patterns adorning the two sides of the coat are not symmetrical.

Our jags

Our scientific missions includes the study and conservation of the last jaguars of the Osa Peninsula in Costa Rica. Our goal is to collect crucial data and list each of the individuals still living in this wild and isolated area. Here is a glimpse of the remaining jaguars already detected by our team.
