Wild cheetahs Acinonyx jubatus of all age classes, from newborns to adults, use their long-distance chirps for communication with conspecifics. We investigated the ontogenetic changes of eight acoustic parameters of the chirps produced by wild-living cheetahs across 14 age classes in Kenya. Chirp maximum fundamental frequency (f0max) was found to b...

Adult cheetahs (Acinonyx jubatus) use long‐distance chirps for calling toward coalition partners (males), mates (both sexes), and cubs (females). Previously, these vocalizations were only investigated in captivity. This study estimates individual and sex‐related acoustic variation of the long‐distance chirps of 20 mature cheetahs (eight males and 1...

Population monitoring is key to wildlife conservation and management but is challenging at the spatial and temporal extents necessary for understanding changes. Noninvasive survey methods and spatial capture–recapture (SCR) models have revolutionized wildlife monitoring by providing the means to acquire data at large scales and the framework to gen...

Objectives Vocalization as part of vigilance behaviour is widespread across animal taxa, including ruminants. Calls of wild-living giraffes have never been recorded and spectrographically investigated. This study reports the acoustic structure of vigilance-related hiss and snort calls of wild-living giraffes Giraffa camelopardalis. ResultsThe hiss...

Understanding cheetah behavior is crucial for both their in situ and ex situ conservation. Many key studies have used direct observation to determine ecological parameters, such as habitat use and prey selection. As cheetahs have a unique spot pattern, researchers are able to identify individuals and track them over time, a key factor in determinin...

To facilitate data collection at large spatial and/or temporal scales, professional scientists increasingly involve members of the public (citizen scientists) in research projects related to the natural world. Citizen scientists volunteer to participate in scientific research and typically collect data under the guidance of a professional scientist...

As cheetah populations continue to decline and cheetah habitat becomes increasingly fragmented, the need for cheetah translocation and reintroduction programs becomes stronger. The majority of translocations into free-ranging environments have been into areas with existing cheetah populations, through which valuable knowledge to guide future reintr...

Cheetahs have unique social and mating systems, as well as hunting techniques. Males are either territory holders defending small territories or floaters roaming in large, overlapping, undefended home ranges. Both spatial tactics are adopted by solitary males or coalitions of males. Females are solitary unless accompanied by offspring. They give bi...
