Determinants of Bird Species Literacy-Activity/Interest and Specialization Are More Important Than Socio-Demographic Variables.

Abstract

Simple SummaryBiodiversity is declining around the world and knowledge about biodiversity declines in a similar way. In this study, we addressed predictors of species knowledge, i.e., the question of what influences or causes species knowledge. The focus was knowledge about common bird species in Germany. Data were collected from July to October 2020 via an online questionnaire, containing demographic data, engagement in birdwatching, interest/activity, and images of 28 bird species native to Germany. Data were collected from adult students, lecturers and administrative staff of the Eberhard Karls University Tübingen. Men identified more species than women, garden owners more than non-owners. Hometown size had no influence. Employees scored higher than students. However, we found that birding specialization was the most important predictor, followed by bird-related interest/activity. We suggest including such questions in addition to conventional demographic questions in the future.Biodiversity is declining, and knowledge about biodiversity declines in a similar way. Previous studies have already addressed predictors of species knowledge. Here, we studied bird species knowledge related to demographics, but also to individual differences in affinity to nature, by including (i) birding specialization and (ii) bird-related activities/interest. Data were collected from July to October 2020 via an online questionnaire, containing demographic data, birding specialization, interest/activity, and images of 28 bird species native to Germany. Participants were adult students, lecturers and administrative staff of the Eberhard Karls University Tübingen. A total of 1967 questionnaires were returned in this study (35.3% male, 53.8% students, 69% had access to a garden). Mean identification score was 16.31 ± 6.38. Thus, participants were able to identify more than half of the species (total species n = 28). Men identified more species than women, garden owners had higher identification scores than non-owners, while hometown size was not significant. A distance to the next forest patch >10 km was related to lower identification scores. Employees scored higher than students. Correlation between species knowledge and birding specialization was high, as was the correlation with bird interest/activity. Higher scores were found in older people. In the linear univariate model, birding specialization and bird interest were the most influential predictors of species knowledge, followed by distance to next forest patch and occupation (student vs employees). Other variables were not significant. We suggest including such measures (interest, attitude, etc.) into further studies and move forward from the urban–rural narrative to more complex analyses of living circumstances.
