A CSIC study documents that the Iberian lynx preys on black kite chicks in Doñana due to drought and rabbit scarcity

Forensic Headline Assessment: The original headline faithfully describes the scientific conclusion without resorting to bias or alarmism.
Research by the Doñana Biological Station, dependent on the CSIC and published in the journal Nature, reveals that prolonged drought and the scarcity of rabbits have led the Iberian lynx to prey on black kite nestlings in the National Park. The study analyzes data collected between 1993 and 2023 on the interaction between both species.
The scientific work details that, given the collapse of rabbit populations caused by infectious diseases and the lack of alternative prey such as ducks during periods of drought, the lynxes modified their hunting habits. This included climbing trees to reach black kite nests located several meters high.
Data indicates that between 1993 and 2012 nest predation was anecdotal, hovering around 1%, but increased significantly in subsequent years of greater water stress. In response, adult kites exhibited displacement behaviors to other territories to avoid the pressure from the felines.
Likewise, the researchers observed indirect effects on other levels of the trophic chain, such as the population increase of the little owl in the face of the temporary decrease of the kites. The scientific team underscores the importance of maintaining long-term monitoring programs to understand the resilience of ecosystems in the face of climate change.
- The study covers the analysis of 1,624 black kite nests between 1993 and 2023 in Doñana.
- The drop in rabbit populations since 2013 drastically reduced the lynx's usual prey.
- Predation of nestlings by the lynx noticeably depleted kite chicks in some seasons.
- Prolonged monitoring has allowed the documentation of cascade effects on other species such as the little owl.
