Real Identification

Through the photographic trapping and the waiting carried out by the project team in the carcass, we can identify and record which ounce has the highest number of slaughters as well as compare it with its area of life and it can improve the indirect search for these individuals.

 Consumption pattern

Over the course of 2013, slaughter records reported that each slaughter carried out by ounces has its own particularity of intake.  Females with pups tend to feed quickly without pause, returning as soon as possible to the "burrow".  In these cases, the technical team of the project has also registered some females in carcass removing soft parts (viscera) and taking the piece to the burrow possibly for the cubs to start eating meat.   Adult males tend to feed on ribs and loins first, then on granite and pallets. Subadultal animals do not have a well-defined pattern and may feed on the inguinal region, limbs, viscera and head.

The natural pattern described by the team, taking into account the way the jaguars eat is: granite, neck, termite and pallet, most of the time rejecting the viscera.

  Habituation

A great contribution of all this study on predations is the subsequent process of habituation, the main goal of the Onçafari Project.

The habituation technique becomes very effective when applied in carcass waiting, since feeding is considered a critical time for the animal, where it is aware of all movements around it. Many jaguars are increasingly accustomed to the presence of vehicles at this time of ingestion, so all stages of the predation process, until habituation are important for the identification of "target" jaguars for the project.

Predation of wild animals  

 The technical team of the Onçafari project also registers wild animals preyed by jaguar, but its registration is more complex due to the smaller size of the prey increasing the speed of its intake.  When found these carcasses are already at a high level of decomposition. Jaguars usually return to feed several nights depending on the size of the preyed animal, but a jaw or alligator provides only a few hours of feeding, leaving little material for registration.
