First breeding record of a one-year-old female Iberian lynx

According to literature, female Iberian lynx ( Lynx pardinus ) start reproducing at 3 years of age. In more recent years, females breeding at 2 years have been recorded in wild populations. Here, however, we describe the first breeding record for a one-year-old female Iberian lynx. This finding was obtained by camera-trapping data, provided by the yearly monitorization of the species that is carried out across its distribution area. A litter of two lynx kittens was found at the south-east limit of the Andujar-Cardeña population. Two camera-traps were set up near the den to identify the breeding female. Photographs obtained confirmed that the breeding female had already been identified the previous year at less than 3 months of age. The case reported here of a yearling female breeding is the first ever from historical distribution range of the species, and as such, is an exceptional event in the reproduction of the Iberian lynx.
