“…Mist nets and camera traps offer different views of the bird community depending on several factors, such as body size, foraging stratum, and secretive behavior (Meng et al 2021). Our results suggest that mist nets and camera traps are sampling techniques that differ widely in the number and identity of bird species they can record but provide complementary information.…”

“…Camera traps are an effective tool for assessing animal diversity, behavior, and habitat use at different spatial and temporal scales (Antunes et al 2022, Puffer et al 2022). Particularly, camera traps can be useful for sampling forest interior birds with low densities, as well as for monitoring secretive, inconspicuous, and ground-dwelling bird species (Suwanrat et al 2015, Murphy et al 2018, Meng et al 2021, Pérez-Irineo et al 2021). Also, camera traps are a convenient tool for working in remote locations that are difficult to access (e.g., steep slopes) or under weather conditions that preclude use of other sampling techniques such as mist nets (Stein et al 2008, Suwanrat et al 2015, Murphy et al 2018, Mere Roncal et al 2019, Fontúrbel et al 2020).…”

Different sampling methods are used to study bird diversity in the tropics, mist nets being one of the most common approaches. However, camera traps have been used for this purpose in the last 20 years. We compared the performance of mist nets and camera traps in sampling the diversity of understory and sub-canopy birds in a Neotropical rainforest. Given its high biodiversity, obtaining accurate bird diversity estimates in these forests is a challenging task. We sampled secondary forest patches in the Colombian central Andes between 2019 and 2021. We compared the effectiveness of both methods based on six comparison criteria (body size, foraging stratum, detection difficulty, habitat specialization, population trend, and migratory status). We recorded a total of 99 bird species: 92 species were captured using mist nets and 37 species using camera traps; 30 species were detected using both methods (mainly generalist and abundant birds). Mist net’s effectiveness was 83%, while camera trap effectiveness was 68%. Differences in sampling effectiveness were mainly determined by body size, as small birds were captured using mist nets, while camera traps often recorded large birds. However, detection difficulty and habitat specialization were also relevant. Camera traps effectively recorded ground-dwelling species that were not captured in mist nets. In contrast, those birds that forage in the sub-canopy stratum were mainly captured in the mist nets but not detected in camera traps. Although both methods detected different species, we found similar patterns regarding estimated species richness among different categories of body size, detection difficulty, population trend, and behavior, but not for habitat specialization. As both methods have advantages and limitations, using mist nets and camera traps together would improve bird diversity estimations. We urge investigators to explore canopy ecology with camera traps, as they provide long-term information that cannot be obtained with other methods.

“…Furthermore, China has several monitoring networks, with approximately 20,000 infrared cameras and approximately 17,000 infrared camera survey sites in 238 monitoring sample areas (Li, 2020). In addition, a recent study also nds that over 290 understory bird species are monitored by camera traps in Chinese nature reserves and forest parks, accounting for 21% of all Chinese bird species, 28% and 51% of phylogenetic and functional diversity of all Chinese bird species (Meng et al, 2021). And there is also a study using camera trap data from ve continents to assess the response of mammalian carnivore to environmental and anthropogenic changes, which found carnivore richness was positively correlated with prey availability (Rich et al, 2017).…”

Forest mammal diversity has declined rapidly due to the widely loss and fragmentation of primary forest habitats, further threatening the functioning and biodiversity of forest ecosystems and emphasizes the importance of the research on forest mammal diversity.This study tried to link forest mammal diversity captured by camera traps with elevation range, contemporary climate, paleoclimate change and human activities in China, a country with diverse forest types, high mammal diversity, and massive anthropogenic disturbance on primary forest. The results showed that the camera traps in 72 Chinese forest sites captured 125 mammal species, accounting for 18% of all mammal species in China. In addition, the phylogenetic and functional diversity of these species accounted for 33% and 49% of all mammal species in China. Notably, forest sites with higher elevation range had higher species richness, higher functional diversity, over-dispersed functional structure, but clustered phylogenetic structure. Stable paleoclimate promoted species richness and functional diversity. Higher contemporary temperature and more precipitation promoted phylogenetic diversity and overdispersed phylogenetic structure. In addition, anthropogenic factors (cropland area and human population size) had weak impacts on forest mammal diversity. These ndings suggest that the mammal diversity in Chinese forest ecosystems is mainly associated with natural environmental variables, supporting the habitat heterogeneity hypothesis, history climate stability hypothesis, and tropical conservatism hypothesis. Meanwhile, the weak links between forest mammal diversity with anthropogenic activities may indicate the important role of forest ecosystems in conserving forest mammal diversity in China.

“…The studies show that riparian forests are an important part of the urban landscape for bird conservation. Riparian forest parks that are surrounded by urban development can provide a more favourable habitat for wintering birds than similar forests in more rural areas [58,59]. This is because urban areas often have more food resources available for birds, such as discarded food from people and bird feeders.…”

Birds are essential bio- or eco-engineers that play a vital role in regulating nature, and their interactions with other environmental aspects can be complex and varied. Forests and birds are intricately intertwined. Through their mutual interaction, they create a harmonious living system that supports both parties. Forest birds play a crucial role in maintaining the balance of nature by dispersing seeds, pollinating flowers, and controlling insect populations. In addition to housing and food, forests offer bird's places to nest, wintering grounds, and thermal refuges. The diversity and distribution of forest birds are critical indicators of forest health and ecosystem function. However, factors such as climate change, habitat loss and fragmentation, and human activities profoundly impact the distribution and abundance of forest birds. Addressing these issues and taking action to mitigate their effects is essential. The forest ecosystem and its avian inhabitants can be protected by restoring degraded habitats, putting conservation practices into place, and promoting sustainable forestry practices.
