“…Plantations such as citrus, sunflower, guava, unripe zizyphus, and jaman were frequently visited for feeding purpose by house crow [23]. Behrouzi-Rad [24] observed that most preferred trees for roosting and nesting purpose by house crow were Ficus bengalensis, Eucalyptus, and Ziziphus aucheri. Kaur and Sahi [25], during their study on community ecology of cattle erget, found vegetation consists of Acacia nilotica (babul), Dalbergia sissoo (sheesham), Eucalyptus, Zizyphus mauritiana, F. bengalensis, F. religiosa, and other plant species.…”

The present article explains some aspects of feeding ecology and behavioral strategies adopted by house crow (Corvus splendens) in urban habitats. The house crow (C. splendens) is an omnivorous, scavenger, and highly opportunistic bird. Feeding ecology and behavior were observed in each study area following a suitable sampling method. House crow significantly feeds in unhygienic places and prefers food items from miscellaneous sources (human refuses, carcasses, etc.) over plant and animal sources during the day time. In the early morning, house crow mostly relied on plant and animal sources as food items. House crow significantly prefers to feed in the morning. Irrespective of the abundance of the various plant species house crow significantly prefers to feed products of five plant species, namely, Ficus religiosa, Azadirachta indica, Ficus racemosa, Ziziphus, Ficus indica, and Artocarpus lacucha. Other plants are only occasionally visited for feeding purposes. House crow significantly prefers to feed in the congregation; however, feeding solitary is not uncommon. House crow utilizes carcasses in congregation with the aid of feral dogs if otherwise unable to crack open carcasses alone. It also feeds on ticks present on the body surface of Sus srcofa. Instances of both inter and intraspecific competitions have been observed. Interspecific competitive events were significantly more common in comparison to intraspecific competitive events. Acridotheres tristis, Acridotheres ginginnianus, Gracupica contra, Passer domesticus, Bubulcus ibis, Egretta garzetta, Columbia livia, and Milvus migrans are bird species, house crow showed aggressive behavior. Apart from this, house crow showed both aggressiveness and appeasement toward Macaca sp. and feral dogs. House crow significantly spends more time in search of food items than actual feeding time. Four types of feeding methods, namely, searching, stealing, specific food offerings, and food retrieved from cached sites were observed to be adopted by house crows. Present outcomes will definitely help us to understand what strategies are adopted by birds to survive in the current urban scenario, at least by this bird. In addition, the present study will give some idea about how to manage the population of this invasive bird species.

“…Wetlands are significant conservation sites due to their rich biodiversity; they are among the most prolific ecosystems in the world, and they support many globally threatened species of different taxonomical groups [1] [2] [3] [4]. The term biodiversity in a wetland's ecosystem encloses all forms of life on the planet and includes all genes, ecosystems, species, and ecological processes in the world [5] [6] [7]. The most important functions of wetlands are preserving the genetic diversity of species and maintaining one of the highest biological productivities in the world [1] [8] [9] [10].…”

Inland wetlands in Abu Dhabi Emirate are wintering and stopover sites for migratory birds of prey. We conducted long-term regular monitoring surveys in Al Wathba Wetland Reserve (AWWR) from January 1995 to December 2022. Both diurnal and occasionally nocturnal surveys were undertaken to record the migratory raptors and owls in the Wetland Reserve. During the study, a total of 1282 regular monitoring visits were undertaken and 27 species of diurnal raptors and owls representing five families and three orders were detected. These represent 57% of the total species of birds of prey recorded in the UAE. Overall, 63% of all the species that we observed were Accipitriformes followed by 26% Falconiformes and 11% Strigiformes. We found that changes in mean daily temperature have a positive effect on raptor species diversity and abundance in the Wetland Reserve. The species encounter rate was higher in low temperature as compared to high temperature and overall regression equation was statistically significant F (4, 1126) = 8.49), p = 0.00). However, the numbers of raptors did not vary significantly across the years (p = 0.51). Western Marsh-harrier (Circus aeruginosus) and Greater Spotted Eagle (Clanga clanga) were recorded to be the most abundant species in the wetland reserve followed by Common Kestrel (Falco tinnunculus). However, the encounter rate of globally threatened Greater Spotted Eagle was detected to have significantly decreased since 2016. Moreover, 63% of the species detected were uncommon and rarely recorded such as 1) Saker Falcon 2) Lanner Falcon 3) Long-eared Owl & Merlin, which were the rare records from the wetland reserve. Furthermore, 27 years of regular monitoring in the wetland have yielded diverse diurnal raptors and owl fauna (H) = 0.83, (E) = 1.43 (Shannon Diversity Index). The results demonstrate that long-term monitoring surveys in arid environments are essential to determine the trends in

“…It is an adaptable, gregarious, noisy, commensal bird, which only lives in close association with humans in urban/semi-urban areas and is not known to live independently from humans [8,9]. They are also known to be associated with coastal human inhabited areas [8] and, although foraging independently and in small groups during the day, they do exhibit communal roosting at night [10,11].…”

Abstract:The house crow (Corvus splendens), a native of the Indian subcontinent, has shown a rapid expansion of habitat range across Eastern Africa, the Arabian Peninsula, Europe and Asia. It is an adaptable, gregarious commensal bird which is regarded globally as an important pest species due to its impacts on livestock, agricultural and horticultural crops and indigenous fauna and as a fecal contaminator of human environments and water resources. Two Maxent (v3.3.3k) models (A) with presence data in Australia and (B) with simulated entry data locations in New Zealand) and a third ArcGIS model (C) with environmental and social layers) are used to determine an overall suitability index and establish a niche-based model of the potential spatial distribution for C. splendens within New Zealand. The results show that New Zealand, particularly the northern regions of North Island, has suitable environments for the establishment of the house crow. In order of suitability Model B showed highest potential land area suitability (31.84%) followed by Model A (13.79%) and Model C (10.89%). The potential for further expansion of this bird's invasive range is high and, if New Zealand is invaded, impacts are likely to be significant.
