“…Therefore, if lockdowns caused reductions in persecution (which remains to be confirmed), we might expect raptors to respond favorably over time, by (re-)using areas that they previously avoided. Global observation records, such as those collated by eBird, as well as local GPS tracking studies could provide useful information on changes in habitat use or foraging behavior (e.g., Linssen et al, 2019 ; Sánchez-Clavijo et al, 2021 ; LeTourneux et al, 2021 ). These could be combined with routinely performed spring and autumn migration counts, which were in some cases possible despite the pandemic.…”

“…In several countries, these lockdowns have increased public interest in urban nature (Roll et al, 2021 ). Analyses of citizen science platforms have shown that lockdowns can result in an increase (Basile et al, 2021 ; Crimmins et al, 2021 ; Manenti et al, 2020 ), but also in a decrease (Crimmins et al, 2021 ; Kishimoto & Kobori, 2021 ; Rose et al, 2020 ; Sánchez‐Clavijo et al, 2021 ) in animal observations by citizen scientists compared with preceding years. Further analyses showed that increases were largely due to increases in observations in urban areas, while no change, or even a decrease in the number of observations, was reported from nonurban areas (Basile et al, 2021 ; Sánchez‐Clavijo et al, 2021 ).…”

Other studies have reported various positive effects of lockdowns on urban wildlife (Driessen, 2021 ; Manenti et al, 2020 ), but more detailed investigations, for example, on birds, suggested that animal responses were largely behavioral, that is, animals were more present in areas with less traffic and fewer humans, but there was no lasting increase in population density (Gordo et al, 2021 ).…”

COVID‐19 lockdown measures impacted citizen science hedgehog observation numbers in Bavaria, Germany

The COVID‐19 pandemic has led to temporary changes in human–animal interactions due to changes in human activities. Here, we report on a surge in hedgehog observations during the first COVID‐19 lockdown in Germany in 2020, on the citizen science Web portal “Igel in Bayern” (Hedgehogs in Bavaria) in Germany. This increase in comparison with previous years was attributed to an increase in the number of people reporting hedgehog observations, rather than an increase in the number of hedgehog observations made by each observer. Additionally, in contrast to other studies on the effects of a COVID‐19 lockdown on observations recorded by citizen science projects, the share of observations made in more urbanized areas during the lockdown time was not higher than the change observed in less urbanized areas. This is possibly a result of the differences in COVID‐19 measures between Germany and other countries where preceding studies were carried out, in particular the lack of measures limiting traveling outdoor activities for citizens.

“…For example, observers' skill levels may change through time, influencing the number of species recorded [9]. Additionally, different methodologies may not report the same number of species and species of conservation concern in the same area [17].…”

Do Citizen Science Methods Identify Regions of High Avian Biodiversity?

Citizen science may offer a way to improve our knowledge of the spatial distribution of biodiversity and endemism, as the data collected by this method can be integrated into existing data sources to provide a more robust understanding of broad scale patterns of species richness. We explored whether data collected by citizen scientists agree on identifying regions of high avian species richness in a well-studied state. We compiled and examined the number of bird species detected in each of the 77 counties of Oklahoma based on published range maps, museum collections, and by five citizen science methods: the USGS Breeding Bird Survey, the Oklahoma Breeding Bird Atlas, eBird, the Oklahoma Winter Bird Atlas, and National Audubon Society Christmas Bird Counts. We also quantified the number of species of conservation concern recorded by each method in each county. A total of 460 species were reported across the state, with the total number of species detected by each method ranging from 40% of this total (Winter Bird Atlas) to 94% of this total (eBird). In general, species totals were poorly correlated across methods, with only six of 21 combinations (28.6%) showing significant correlations. Total species numbers recorded in each county were correlated with human population density and county area, but not with mean annual temperature or precipitation. The total number of species of conservation concern was correlated with the total number of species detected, county area, and precipitation. Most of the citizen science methods examined in this study were not explicitly designed to identify regions of high biodiversity and so efforts to use these methods for this purpose should be employed only cautiously and with a thorough understanding of potential biases.
