Human-wildlife interactions have been documented throughout history and across cultures via wildlife-centric art, lore, superstitions, and stories. For example, the oldest known drawing of wildlife is 45,000 years old and depicts social interactions among Sulawesi warty pigs (Sus celebensis) (Brumm et al. 2021). Furthermore, the value people place on different species – which can be mediated by past experiences, folklore, media, utility, and psychological perceptions – informs the ways we interact with wildlife (Linnell et al. 2003, Dickman 2010, Frank 2016, Wilkinson 2023). For instance, the reestablishment of wolves (Canis lupus) in Southern Scandinavia has incited concern amongst the public despite the infrequency of fatal attacks that have occurred in the last 300 years (Linnell et al. 2003). Thus, our interaction with wildlife deeply influences our appreciation of, and attitudes towards, different species ((Dickman 2010, Wilkinson 2023).
The connection humans have with wildlife can manifest into powerful decisions, both positive and negative, for wildlife. For instance, previous studies show that animals considered ‘attractive’ or ‘charismatic’, are often favored in conservation practices compared to those that are considered unappealing (Stokes 2007, Marešová and Frynta 2008, Marešová et al. 2009, Frynta et al. 2010, 2011, Landová et al. 2012, Lišková and Frynta 2013, Lišková et al. 2015). Moreover, Wilkinson (2023) recently highlighted the powerful role human connection to species or individuals can have for the conservation of wildlife and ecosystems. These studies have provided pieces of a framework for understanding public attitudes towards wildlife species and its potential for shaping the interactions between humans and wildlife. Consequently, the species which we ignore, consider a nuisance, attempt to domesticate, protect, and overexploit to extinction are deeply tied to our perception of wildlife (Perry et al. 2020, Schell et al. 2020, Basak et al. 2022). Yet, how coloration, which is vast and varied in the animal kingdom, may mediate the human perception and appreciation of animals has rarely been examined.
As a visual species, one of the first characteristics that humans perceive about a species is its physical appearance, including its color (Messmer 2000, Courchamp et al. 2006). Stories of wildlife in many cultures can vary with coloration (de Farias 2020). In European folklore, domestic black cats (Felis catus) are perceived as omens of misfortune (Jones and Hart 2020). Similarly, jaguars (Panthera onca) in Shipibo lore take on a variety of connotations which often varied based on coloration of the animal. Yellow jaguars are sometimes viewed as masculine, protective, diurnal, and/or more than human, whereas black jaguars were viewed as feminine, nocturnal, evil, associated with sorcery, and/or less than human (Saunders 1998). This intertwined connectivity of wildlife and people has strongly influenced our aesthetic appreciation of, and attitudes towards, different wildlife (Linnell et al. 2003, Dickman 2010, Frank 2016, Wilkinson 2023, Estien 2023).
While the coloration of wildlife may have important implications for humans such as facilitating spiritual/mystical connections, or aid in species identification, it also serves many important ecological roles (Mendoza et al. 2011, Legge and Robinson 2017, Castillo-Huitrón et al. 2020). Coloration in wildlife evolved as a form of inter- and intraspecific communication, thermoregulation, and camouflage from predator or prey (Caro 2005). While many species – especially mammalian species – often exist within a fairly finite range of colors (Caro 2005), sometimes individuals with rarer coloration can appear as a result of random mutations (Fertl and Rosel 2009, Kreling 2023). These individuals with altered coloration can be found throughout the animal kingdom (Caro 2005, McCardle 2012). While individuals with conspicuous coloration may be relatively rare within any given population, humans may value conspicuous colors differently based on a combination of biases and social paradigms (Duckitt et al. 1999). For example, individual animals with favorable color morphs (henceforth “charismatic coloration”) may experience opposing actions from people such as being trophy hunted (Johnson et al. 2010) or protected (Tarrant et al. 1997, de Pinho et al. 2014). In addition, Kreling (2023) speculated that in cities, charismatic coloration may become more prevalent due to higher exposure to mutagens and lower predation risk, thereby increasing the importance of understanding how humans interact with these individuals. While we understand many of the genetic and physiological factors that lead to coloration, little has been done to explore the underlying human preference for rare colorations among wildlife and how these perceptions alter human-wildlife interactions.
Here, we examine human attitudes towards wildlife with charismatic coloration. First, we discuss the social drivers that can influence how humans perceive the coloration of wildlife, focusing on the psychology of scarcity, symbolism and lore, and individualism. We then briefly discuss melanin-based colorations, focusing on melanism, albinism, and leucism; three rare colorations that have potential to influence how people interact with wildlife. Finally, we examine how human-wildlife interactions with charismatically colored individuals vary from those with default colorations (i.e., wildtype) through three case studies. Our three case studies focus on four species with different ecosystem roles that humans commonly interact with: (1) coyotes (Canis latrans), a highly plastic carnivore that holds a contentious relationship with human society due to instances of human-wildlife conflict, but also in their charismatic profile as urban carnivores, (2) eastern gray squirrels (Sciurus carolinensis), a ubiquitously urban mammal in many North American and European cities that are sometimes beloved by people, but also capable of causing structural damage that contributes to their perception as a nuisance, and (3, 4) white and black-tailed deer (Odocoileus sp.), an herbivore that often assumes the pest role in urban and suburban areas due to their propensity to cause property damage via garden grazing and vehicle collisions.
