- ItemThe California Quail (Callipepla californica) in Chile and Argentina: introduction history, current distribution, and biological features(2023) Andrews, Benjamín; Zurita Redón, Carlos Nicolás Felipe; Jaksic Andrade, FabiánAbstract Background Little is known about the California Quail (Callipepla californica) as an invader in Chile and Argentina. Our goal was to review the history of its introduction and to provide updated information on its spread and current geographic distribution in those two neighboring countries, together with information on its body measurements (weight, wing length, and tail length), diet (granivory, frugivory), parasitism (endo and ecto), and other interspecific interactions (competition and predation), including hunting by humans. Methods and result We conducted a selective review of the history of introduction, distributional records, and biological features of C. californica, as recorded in mainstream journals, landmark monographs and books, and internet sources. We also measured specimens collected in central Chile and analyzed their stomach contents. We report that the California Quail was first introduced to Chile in 1864, and it now spans ca. 2,800 km in the country. From stocks in Chile, this bird was back-introduced to California (USA), and also introduced to Argentina in the 1920s, now spanning ca. 1,400 km in the country. It is currently abundant and legally hunted in both countries. In Chile, its non-breeding diet is strongly granivorous. In Argentina it feeds similarly. In Chile, endoparasites are three species of nematodes, one of cestodes, and two of coccidian protozoans; ectoparasites are three species of hard ticks, one of mites, and two of chewing lice. No such data are available from Argentina. In Chile, combining autumn and winter samples we obtained mean weights of 194.4 (± 9.0 SD) g for 21 adult males and of 183.9 (± 14.3 SD) g for 10 adult females, figures similar to those reported for C. c. brunnescens in California (USA), which we suspect is the subspecies now spread over in Chile and Argentina. Discussion We propose that interesting scientific opportunities are being missed regarding the population genetics of a species with introductions and back-introductions that may have left founding effects and genetic bottlenecks in Chile and Argentina, and perhaps some peculiar “Chilean” genetic markers among California (USA) populations. We also raise the question whether this introduced species may be deemed invasive, calling for research to determine its impact in its new environment.
