“…And, it has been pointed out that spatial and temporal comparisons of these typologies are necessary to assess the effects of declines in human activity (Montgomery et al, 2021 ). Since the pandemic, changes in animal responses have been examined in studies for changes in wildlife–vehicle collisions, observations by camera traps, and the records of citizen science data (Jasińska et al, 2022 ; Łopucki et al, 2021 ; Manenti et al, 2020 ). However, there have been no detailed studies of changes in the behavior of urban mammals.…”

In 2020, a lockdown was implemented in many cities around the world to contain the COVID‐19 pandemic, resulting in a significant cessation of human activity which have had a variety of impacts on wildlife. But in many cases, due to limited pre‐lockdown information, and there are limited studies of how lockdowns have specifically affected behaviors. Foraging behavior is inherently linked to fitness and survival, is particularly affected by changes in temporal activity, and the influence of human disturbance on foraging behavior can be assessed quantitatively based on foraging duration and quantity. The purpose of this study was to determine whether and how the fruit‐foraging behaviors of two omnivores, the Japanese badger (Meles anakuma) and the raccoon dog (Nyctereutes procyonoides), were influenced by the decrease of human activity associated with lockdowns. Specifically, by comparing to a previous study in 2019–2020, we attempted to determine (1) whether foraging behavior increases during the daytime? (2) whether the duration of foraging per visit increases? and (3) what factors animals select for in fruiting trees? The results of the initial investigation showed that the foraging behavior of both species in 2019 was almost exclusively restricted to the nighttime. But as opportunities for foraging behavior without human interference increased in 2020 due to the lockdown, both species (but especially raccoon dogs) showed substantial changes in their activity patterns to be more diurnal. The duration of foraging per visit also increased in 2020 for both species, and the selection during foraging for both species shifted from selecting trees that provided greater cover in 2019 to trees with high fruit production in 2020. Our results show how human activity directly affects the foraging behavior of wildlife in an urban landscape.

“…In Glacier National Park in Montana, USA, resumption of recreational hiking after a COVID lockdown (Anderson et al, 2023) resulted in consistent negative responses across most of the 24 wildlife species assessed, with fewer detections, reduced site use, and decreased daytime activity, and the authors urged immediate understanding of the fitness consequences of these spatiotemporal changes to inform management decisions in protected areas. In urban forests of Warsaw, Poland, roe deer ( Capreolus capreolus ) rapidly shifted their activity toward daytime when forests were closed for visitors, and, in turn, toward night‐time when the number of visitors was higher after the lockdown (Jasińska et al, 2022). In a Malaysian national park, however, mammalian diel activity patterns for a wide variety of species did not differ whether the park was open or closed to tourism (Ota et al, 2019).…”

Corcovado National Park (CNP) in Costa Rica is an important destination for ecotourism. However, the effects of increasing human visitation on wildlife needed evaluation and the global COVID‐19 pandemic lockdown provided a scenario to test the effects of tourist activity on wildlife presence and activity. We performed a camera trap survey initiated during the COVID‐19 lockdown and continuing when tourism resumed (Oct 2020–May 2021). We deployed camera traps on walking trails, including those that remained closed to tourists at all times (control) and those open to tourists after the lockdown was lifted (experimental). With an effort of 2312 trap nights, we assessed the photo rates and diel activity patterns of humans, 11 other species of mammals, and two species of birds. Our results suggest that wildlife species were already habituated to tourists in this area, and thus their behavior and activity did not change after the lockdown was lifted.

“…Roe deer ( Capreolus capreolus ) was among the species most strongly impacted by lockdown in Slovenia [ 41 ]. This species appears to be capable of rapid changes in behavior, adjusting its activity patterns to anthropogenic load [ 44 ]. Therefore, we selected roe deer as the focal species for our analysis of lockdown influence, as it accounts for the highest number of roadkills among ungulates in Lithuania [ 45 ].…”

“…Possible explanations for these observed patterns include differences in accident reporting [ 5 , 19 ], changes in animal behavior and habitat use due to reduced human activities [ 18 , 19 , 32 , 47 , 48 ] and even gaps in previous knowledge about animal presence [ 49 ]. Disruptions in research activities and conservation enforcement may also obscure the true picture of these changes [ 9 , 50 ], as species react differently to disturbances [ 10 , 13 ], and this was also observed in the context of roadkill [ 44 ].…”

The impact of COVID-19 restrictions on human and vehicular mobility on the number of roadkills of wild mammals, and roe deer in particular, was assessed in Lithuania. We statistically analyzed the distribution of all mammals and roe deer (Capreolus capreolus) as the most abundant species annually from 2002 to 2022 and monthly from 2020 to 2021, including during the two restriction periods. Notably, there was a marked decrease in roadkill incidents on main, national and regional roads, particularly in April–May 2020 (the beginning of lockdown period I) and November–December 2020 (the beginning of lockdown period II), 5.1–20.8% and 33.6–54.4%, respectively. During these months, collisions with mammals on the A14 main road were reduced by 75–90%. However, there was a significant increase in the number of roadkills in urban areas, resulting in the total number of mammal–vehicle and roe deer–vehicle collisions in 2020 and 2021 being higher than expected based on long-term trends. However, after restrictions were eased, collision numbers with wildlife on the main, national and regional roads increased again and became higher than expected.
