The Iberian lynx (Lynx pardinus) is much more than a symbol of conservation. With its majestic appearance, pointed ears, and piercing gaze, this feline has fascinated naturalists, photographers, and nature lovers for generations. The Iberian lynx (Lynx pardinus) is one of the four extant species within Lynx, a genus of medium-sized wild cats. The Iberian lynx is endemic to the Iberian Peninsula in southwestern Europe, existing exclusively on the Iberian Peninsula. This article delves into the dietary habits of this unique species, highlighting the critical role of prey availability in its conservation.
Conservation Status and Distribution
For years, the Iberian lynx held the unfortunate record of being the most endangered feline on the planet. In the early 2000s, the population had dropped to fewer than 100 individuals. By the turn of the 21st century, the Iberian lynx was on the verge of extinction, as only 94 individuals survived in two isolated subpopulations in Andalusia in 2002. Thanks to intense conservation programs, today there are over 2,000 lynxes living in the wild-and the number keeps growing! Still, it remains an endangered species. Conservation measures have been implemented since then, which included improving habitat, restocking of rabbits, translocating, reintroducing and monitoring Iberian lynxes.
The Iberian lynx was once present throughout the Iberian Peninsula. In the 1950s, the northern population extended from the Mediterranean to Galicia and parts of northern Portugal, and the southern population from central to southern Spain. Populations declined from 15 subpopulations in the 1940s to only two subpopulations in the early 1990s, most noticeably in Montes de Toledo and Sierra Morena. Before 1973, it was present in Sierra de Gata, Montes de Toledo, eastern Sierra Morena, Sierra de Relumbrar and coastal plains in the Doñana area.
Dietary Specialization: The Importance of Rabbits
Although it can hunt birds or small rodents, 90% of its diet consists of wild rabbits. Rabbits are its favorite meal! This specialization makes it very vulnerable: when rabbit populations drop (due to disease or human pressure), the lynx suffers too. Small deer and fallow deer, ocellated lizards, or garden dormice also form part of its diet. The energy requirements for this Lynx have been found to be 1 rabbit per day.
The Iberian lynx's dependence on rabbits is a critical factor in its survival. A study of feeding behavior and taphonomic characterization of non-ingested rabbit remains produced by the Iberian lynx highlights this relationship. The decline in rabbit populations due to diseases like myxomatosis and hemorrhagic disease in the 20th century significantly threatened the lynx.

Hunting Strategies and Adaptations
The Iberian lynx has excellent eyesight, adapted to both daylight and low-light conditions. It has exceptional vision (almost night vision). Its large eyes, combined with its natural stealth, allow it to spot and stalk prey even at dusk.
Like all felines, the lynx retracts its claws when walking, so its footprints appear “clean,” without any claw marks. Its tracks don’t show claws. This is one of the clues guides use to identify its tracks during observation routes. The Iberian lynx prefers heterogeneous environments of open grassland mixed with dense shrubs such as strawberry tree, mastic, and juniper, and trees such as holm oak and cork oak.
Competition and Ecosystem Role
The Iberian lynx competes for prey with the Iberian wolf (Canis lupus signatus), red fox (Vulpes vulpes), the Egyptian mongoose (Herpestes ichneumon), and the European wildcat (Felis silvestris). These animals are primarily nocturnal, except during the winter months when they have diurnal activity peaks.
Reproduction and Diet
Breeding season usually runs from March to May. Cubs are born in spring… and gain independence fast! Females typically have 2 to 4 cubs, which stay with their mother for about 10 months. After that, they begin their solitary journey to find their own territory, though some may remain in their mother’s area for a while longer. The kittens become independent at 7 to 10 months old, but remain with the mother until around 20 months old. Survival of the young depends heavily on the availability of prey species. The sole caregivers for cubs are bringing her cubs along to learn to hunt for themselves.
Threats to the Iberian Lynx
The Iberian lynx is threatened by habitat loss, road accidents, and illegal hunting. Habitat loss is due mainly to infrastructure improvement, urban and resort development and tree mono cultivation, which fragments the lynx's distribution. Further, the lynx was hunted as "vermin" under a law passed under Francisco Franco, from the 1950s to the late 1970s, when the hunting of lynx was prohibited. The largest threat facing this Lynx is habitat destruction and the destruction of its prey base. The prey also suffered a major blow when an introduced disease - poxvirus myxomatosis - to which the European Hare had no natural immunity and was nearly decimated. By the time they started building a resistance to this disease and the numbers started to recover, a new disease -viral hemorrhagic pneumonia - took its place and killed a large number of adult rabbits. This cat also suffers at the hands of man, frequently being killed by traps and snares set for rabbits, and by being hit by cars as the number of roads increase.

Conservation Efforts and Monitoring
The Spanish Government is now in the process of developing a national conservation effort to save the Iberian Lynx. The Iberian lynx is fully protected and listed on CITES Appendix I, on Appendix II of the Berne Convention on the Conservation of European Wildlife and Natural Habitats and on Annexes II and IV of the Habitats Directive of the European Union. The Spanish National Commission for the Protection of Nature endorsed the Iberian Lynx Ex Situ Conservation Breeding Program to serve as a "safety net" by managing the captive population and also to "help establish new Iberian lynx free-ranging populations through reintroduction programmes." Before release of captive-bred cats, their natural habit may be simulated to prepare them for life in the wild. A 2006 study used a non-intrusive monitoring system involving cameras to monitor the demographics of both lynxes and rabbits residing in Sierra Morena. Since a 2007 outbreak of feline leukemia virus (FeLV), wild lynxes are tested periodically for possible disease.
In 2002, the Jerez Zoo confirmed it had three females and was developing a plan for a captive breeding program. One of those females was Saliega, captured as a kitten in April 2002. She became the first Iberian lynx to breed in captivity, giving birth to three healthy kittens on 29 March 2005 at the El Acebuche Breeding Center, in the Doñana National Park in Huelva, Spain. Over the following years, the number of births grew and additional breeding centers were opened. In Portugal, the Centro Nacional de Reprodução do Lince-Ibérico established a breeding center near Silves, Portugal and has since nurtured 122 individuals all born in the breeding center, of which 89 survived. 73 of them were reintroduced in the wild. There were 14 surviving kittens in 2008 and 15 in 2009. In 2010, intense rain and health issues resulted in lower reproductive success, i.e. In March 2013, it was reported that Iberian lynx embryos and oocytes had been collected and preserved for the first time.
Identifying Individual Lynx
Each individual has a unique “pattern”. The lynx’s coat spots act like a fingerprint-no two lynxes have the same pattern. This helps biologists identify and track individual animals in the wild using camera traps and direct observation. Thanks to camera traps, the Iberian lynx is also one of the most closely monitored species in the world. WWF scientists also use radio collars to follow lynxes that venture into new territories. These collars help prevent poaching and identify which roads are too dangerous for lynxes to cross. Occasionally, more expensive satellite collars are used to collect more detailed and accurate data. Thanks to all this monitoring, we’ve learned huge amounts about Iberian lynx behaviour.
Genetic Diversity
The genetic diversity of the Iberian lynx is lower than in any other genetically impoverished felid, which is a consequence of fragmentation, a population bottleneck, and isolation of population units. Iberian lynxes in Doñana and Andujar differ genetically at microsatellite markers.
Habitat and Territory
The Iberian lynx marks its territory with its urine, scratch marks on the barks of trees, and scat. The home ranges of adults are stable over many years. Camera trapping surveys in the eastern Sierra Morena Mountains between 1999 and 2008 revealed that six females had home ranges of 5.2-6.6 km2 (2.0-2.5 sq mi).
