“…The importance of agricultural land for the Spotted Owlet is well established (Mahmood-ul-Hassan et al 2007, Ali and Santhanakrishnan 2015, Vanitha et al 2018. However, in the case of the endangered Forest Owlet, its apparent preference for agricultural land may raise major conservation challenges.…”

Species with highly restricted distributions are intriguing especially when they co-occur with similar and related species that are more widely distributed. They are also of conservation concern because of their restricted distributions and low population size. The Forest Owlet (Athene blewitti) is an endangered species endemic to the central Indian landscape that occurs in apparently unconnected pockets. Two other species of owlets, with wide distributions in India, Jungle Owlet (Glaucidium radiatum) and Spotted Owlet (Athene brama) co-occur with Forest Owlet. Understanding how species use the habitat matrix is central to prioritizing conservation action. We studied the three species across an extensive part of the predicted range of Forest Owlets through 350 surveys.Our results indicate that Jungle Owlet occupancy (ψ = 0.5896, SE = 0.08) was highest, followed by Forest Owlet (ψ = 0.2517, SE = 0.10), and Spotted Owlet (ψ = 0.1781, SE = 0.07). The Forest Owlet showed a preference for stands of forests with large trees but not necessarily with closed canopies, as well as open habitats (agricultural land cover). The Spotted Owlet showed a preference for agricultural land cover with lower litter and bare ground cover. In contrast, the Jungle Owlet showed a preference for dense forest and canopy cover. The preference for agricultural cover by the Forest Owlet provides important insights into our understanding of the ecology of this owlet. Most significantly, it brings up several conservation challenges for managing this endangered species across a human-use landscape.RESUMEN. Las especies con una distribución altamente restringida son intrigantes especialmente cuando co-occurren con especies cercanamente emparentadas y similares que están más ampliamente distribuidas. Estas especies son también de interés para la conservación por su distribución restringida y bajo tamaño poblacional. Athene blewitti es una especie amenazada y endémica al paisaje del centro de India donde se encuentra en bolsillos de hábitat aparentemente desconectados. Otras dos especies de búhos, con una amplia distribución en India, Glaucidium radiatum y Athene brama co-occurren con Athene blewitti. Comprender como la especie utiliza la matriz del hábitat es central para priorizar acciones de conservación. Estudiamos las tres especies a lo largo de una porción extensiva del rango predicho de Athene blewitti usando 350 muestreos. Nuestros resultados indican que la ocupación de Glaucidium radiatum (ψ = 0.5896, SE = 0.08) fue la más alta, seguida por Athene blewitti (ψ = 0.2517, SE = 0.10) y Athene brama (ψ = 0.1781, SE = 0.07). Athene blewitti mostro una preferencia por fragmentos de bosque con árboles grandes, pero no necesariamente con dosel cerrado, así como hábitats abiertos (cobertura de agricultura). En contraste, Athene brama mostró una preferencia por bosque denso y con alta cobertura de dosel. La preferencia por coberturas de agricultura por parte de Athene blewitti provee información importante para nuestro entendimiento de la ecología de e...

“…Nest site selection is considered to be a crucial factor for potential reproductive success in birds' species. Birds are likely to prefer nest sites that protects their nests from predators and comes up with greater food supply (Liebe zeit and George 2002, Marshall andCooper 2004, Ali andSanthanakrishnan 2015). Except Chestnut-tailed Starling, other three sturnid species in JU campus used more than one nesting site.…”

“…On the other hand, the characteristic of cavity nesting (e.g. tree holes, building holes) in Common Myna, Jungle Myna and Chestnuttailed Starling facilitates them by providing suitable microclimatic condition for eggs and chicks and reduces predation risks to nests (Nilsson 1986, Ali andSanthanakrishnan 2015). Nesting trees: A total of 20 species of plants in JU campus was recorded as nesting trees for mynas and starlings (Table 1).…”

Nesting patterns of four species of mynas and starlings, Common Myna (Acridotheres tristis), Jungle Myna (Acridotheres fuscus), the Asian-pied Starling (Gracupica contra) and Chestnut-tailed Mtarling (Sturnia malabarica) were studied in Jahangirnagar University campus from March to September in 2016. Nests were searched systematically throughout the study area and nesting parameters like nest dimensions, nest-site selection, tree species preference, nesting materials, clutch size and nesting success were examined. A total of 101 nests were recorded where 31 nests were of Common Myna, 10 of Jungle Myna, 49 of the Asian-pied Starling and 11 nests were of Chestnut-tailed Starling. Overall, the sturnids preferred nesting on trees (n=84) to anthropogenic structures (n=17). Common myna showed maximum variation in nest-site selection using tree holes (n=12), tree branches (n=10) and building cornices, holes or crevices (n=9) whereas Chestnut-tailed Starling nested only in tree cavities (n=11). Jungle Myna built nests both in tree holes (n=4) and in building holes and crevices (n=6). The Asian-pied Starlings built their domed nests mostly on tree branches (n=47) where 69% nests were peripheral and 31% were central in position. Out of 20 species of trees utilized for nesting purpose, the majority of nests were built on Whites iris Albizia procera (n=18) followed by Neem Azadirachta indica (n=10) and Mahogany Swietenia mahagoni (n=10). The nests were constructed between 2 and 18m (8±3.8m) from the ground level. Among 19 types of nesting materials recorded, twigs, leaves, straws, grasses, feathers, plastics and polythene were frequently used by all four species while the Asian-pied starling used more rubbish materials than other species. Highest nesting success (80%) was recorded in Common Myna whereas the Asian-pied Starling, Chestnut-tailed Starling and Jungle Myna had 77.8%, 75% and 66.7% of nesting success respectively. Adaptions to using different nesting sites in Common Myna and comparatively higher nesting height in the Asian-pied Starling may have facilitated the greater nesting success. Bangladesh J.

“…Nest site selection is thought to be an important component in bird species' reproductive success. Birds are more likely to select nest locations that protect their nests from predators and provide a larger food supply [14]. Sturnid species' selection of varied nesting places, including human settlements, demonstrates their excellent tolerance to urbanisation [15].…”

Aims: The study aims to study the resource partitioning and nesting behaviour in four species namely Common Myna, Bank Myna, Brahminy Starling, and Asian Pied Starling nesting in human settlements. Place and Duration of Study: The study was conducted from January 2022 to July 2023 in peri-urban areas of Ajmer city, Rajasthan, India. Methodology: Using observations and point-count transects, we examined the nesting preferences, heights, and materials used by these species. Results: The findings reveal that all four species demonstrated a remarkable adaptability to urban environments by selecting man-made structures as their preferred nesting sites. Common Mynas, in particular, displayed a preference for a variety of human constructions, such as buildings and building cracks, and utilized materials like twigs, straws, plastic, paper, and cotton. Conclusion: This study highlights the importance of considering wildlife adaptation in urban planning and conservation efforts, as these birds thrive in human-altered landscapes. The nesting behaviors and adaptation of these Sturnidae species in urban environments reveal their ability to coexist with human development. Understanding these interactions is crucial for both avian ecology and urban planning, as it sheds light on the intricate relationships between wildlife and changing landscapes.
