“…Canopy gaps maintain food resources for insectivore-nectarivore birds in tropical forests, particularly during the dry season (Marod et al 2010). Several studies have shown that insectivorenectarivore birds in tropical forests can be captured in areas with low canopy cover or in open habitats (Levey 1988;Pearman 2002;Chettri et al 2005;Smith et al 2015). Differences among bird groups are generally consistent with differences in the abundance of foraging substrata (George et al 2005).…”

Siri S, Ponpituk Y, Safoowong M, Marod D, Duengkae P. 2019. The natural forest gaps maintenance diversity of understory birds in Mae Sa-Kog Ma Biosphere Reserve, northern Thailand. Biodiversitas 20: 181-189. We compared the species composition and feeding guilds between under closed canopies and forest gaps in the low-elevation montane evergreen forest in Mae Sa-Kog Ma Biosphere Reserve. Monthly mist netting was used to capture birds from January 2015 to December 2017. In total, 958 individual birds belonging to 65 species were captured over 25,920 sampling hours. Of the total number of birds, 475 were from 51 species (Shannon-Wiener index: H' 2.974) under closed canopies and 483 were from 47 species (H' 2.985) in forest gaps. The number of bird species in gaps increased rapidly and constantly through 1 year following gap creation. Forest gap localities contained 48% of the understory birds in the area. Foliage–gleaning insectivores were the dominant bird feeding guild in both areas. Some species such as Erythrura prasina is a nomadic bird were found on first year of the forest gap only. Overall, we found that the forest gaps created by natural disturbances in the Mae Sa-Kog Ma Biosphere Reserve had no negative impact on the diversity of understory bird communities. The natural forest gap are created by intermediate disturbance promotes a relatively high biodiversity of birds in the ecosystem.

“…An estimated of 56.48 kha of tree cover loss per annum has been recorded in the Philippines with 39% associated with deforestation and 41% with shifting agriculture (Global Forest Watch, 2018;Tanalgo & Hughes, 2019). Conservation of primary forests is essential (Mittermeier, Turner, Larsen, Brooks, & Gascon, 2011;Pimm et al, 2001) but can only protect a small area and thus nonprimary forests (e.g., plantations and agroforest systems) are also essential for the survival of many species (Achondo et al, 2011;Gordon, Manson, Sundberg, & Cruz-Ang on, 2007;Jose, 2009;Moguel & Toledo, 1999;Smith et al, 2015). However, few comparative studies on bird diversity across habitats have been conducted in the Philippines, with most focusing on natural ecosystems, for example, primary forests (e.g., Ambal et al, 2012;Balete, Tabaranza, & Heaney, 2006;Española, Collar, & Marsden, 2013).…”

Rapid assessment biodiversity surveys are usually employed when resources or time is limited. In terrestrial ecosystems, birds are important ecological indicators of ecosystem health. Our study used rapid inventories to show that species differ across habitat types; species richness and rarity were higher in pristine habitats (native and restored areas) while nonprotected habitats (e.g., plantations and orchards) mainly had common and nonendemic species. Our findings demonstrate the importance of collective local biodiversity studies in elucidating species diversity patterns, though is equally important to bolster regional conservation prioritization. We hope that our findings will benefit future decision-making for sustainable development and conservation planning.

As climate warms, more species will become restricted by climate on a region‐wide level.…”

“…To determine which bird species to model in East Africa, we used species recorded by Smith et al. (2015) from mist‐net surveys conducted December 2012–January 2013 and December 2013–January 2014 (when migratory species were present) in Nyeri County, Kenya and by Schooler (2019) from point‐count surveys conducted December 2017–January 2018 in Kiambu and Muranga counties, Kenya. Potential pest‐consuming species were selected from this pool ( n = 203) through diet, length, and weight (del Hoyo et al., 2018).…”
