“…For instance, less number of species and individuals were counted in site II as this site was more exposed to disturbances than site I and III. According to Novaes and Cintra, species richness and abundances of birds are determined by distance of the dumping sites towards human settlements and other activities [35]. Benitez-Lopez et al also found that bird population size is decreased with proximity of roads [36].…”

Waste disposal sites are predominantly used as feeding sites for generalist birds. The main objective of this study was to assess the diversity and abundance of birds from three waste disposal sites in and around Gubre sub city, Guraghe zone in 2017. Data were collected using point count techniques from 6:00−10:00 a.m. in the morning and 4:00−6:00 p.m. in the afternoon for three consecutive days each in three study sites. During this study, a total of 2566 birds belonging to 17 species, 7 Families and 6 Orders were recorded. From the 17 identified species of birds, 11 species each were from site I and III, while the remaining 7 species were recorded from site II. Among the seven identified families, Accipitridae was numerically the dominant family represented with 7 species, while Columbidae and Scopidae were the least dominant families represented with 1 species each. At species level, Hooded vulture (Necrosyrtes manachus) was the most abundant bird species. The total abundance of birds was significant (ANOVA result, p=0.00) difference among the three sites. In general, highest number of individual birds were counted in site I (1210) followed by site III (974) and site II (382). A significant difference in the abundance of birds between morning and afternoon was also observed (t-test, p=0.044). Greater numbers of birds were counted in morning in all study sites (range: 93 in site II and 651 in site I). Site I was found to be with relatively higher value of species diversity (H'=1.2) than Site III (H'=1.01) and Site II (H'=0.90). In the study area, waste collectors, domestic dogs, cats and vehicles were considered as threats for waste dependent birds. More studies are required to make a complete list of available bird species in the study area.

“…Also, the total amount of food resources available, which is a key attractant to vultures, is one of the main ecological factors that affect the fine-scale spatial distribution of vultures (Permalee, 1954;DeVault et al, 2005;Novaes & Alvarez, 2010;Novaes & Cintra, 2013). Black Vultures use vision as the main sensory mechanism to find food resources (Houston 1986), being able to detect food sources within a 90-km radius or minimize the availability of organic waste produced every day by several human activities.…”

“…For instance, a single collision involving two Turkey Vultures (Cathartes aura) in 2012 near the Manaus International Airport (MAO) resulted in engine failure and financial losses of ~US$ 750,000 (CENIPA, 2017). The spatial distribution of birds in urban environments is related to several factors including the presence of food resources and shelters (roosting sites) as, for example, in Black Vultures (Coragyps atratus) (Novaes & Cintra, 2013). It is therefore possible to reduce birdstrike probability by simply modifying and monitoring the environment surrounding airports and rendering them less attractive to birds as foraging habitats (Blackwell et al, 2009;Martin et al, 2011).…”

Collision rates between aircraft and birds have been rising worldwide. The increases in both air traffic and population sizes of large-bodied birds in cities lacking urban planning result in human-wildlife conflicts, economic loss and even lethal casualties. Black Vultures (Coragyps atratus) represent the most hazardous bird to Brazilian civil and military aviation on the basis of their flight behavior, body mass and consequently physical damage to aircraft following collisions. This study investigated how storage apparatus and type of organic residue discarded in public street markets modulate the spatial distribution and abundance of urban Black Vultures in the largest city in the Amazon (Manaus, Brazil). We estimated Black Vulture abundance in relation to the type of solid human waste (animal or plant), the type of waste storage containers and market sizes in terms of the number of vendor stalls at 20 public markets. We also visually quantified the abundance of Black Vultures in urban markets in relation to air traffic. Our results suggest that urban solid waste storage procedures currently used (or the lack thereof) are related to the occurrence and abundance of Black Vultures. Moreover, storage type and the proportion of animal protein (red meat and fish) within rubbish bins directly affects foraging aggregations in vultures. We recommend that policymakers should invest more efforts in building larger and more resistant closable waste containers to avoid organic solid waste exposure. We also identified five outdoor markets as urgent priorities to improve waste disposal. Finally, our waste management guidelines would not only reduce aviation collision risks but also benefit human health and well-being in most cities.

“…The movement pattern of this species is mainly between their roosting sites and their food sources (Novaes & Cintra, 2013). They tend to be faithful in terms of movement to the food source area (DeVault, Reinhart, Brisbin, & Rhodes, 2004;Novaes & Cintra, 2015).…”

Scavenger birds exploiting rubbish dumps: Pathogens at the gates

Different bacteria are present in rubbish dumps used as food resources by various bird species. Birds may be good indicators of the presence of zoonotic diseases in these sites since they can be infected with zoonotic pathogens by foraging on organic waste, and can also act as carriers. We studied if foraging in rubbish dumps increases the occurrence of Salmonella spp. and Chlamydia psittaci in American black vultures (Coragyps atratus, hereafter black vultures) from northwest Patagonia. We compared these pathogens isolated from or detected in cloacae and oropharynx swabs in two different groups of black vultures: individuals trapped in (a) the Patagonian wild steppe and (b) in a rubbish dump. We found that black vultures are colonized by Salmonella spp. (particularly Salmonella enterica serotypes Typhi, Paratyphi A, Salmonella enterica subsp. arizonae) and Chlamydia psittaci. Interestingly, there were differences in the prevalence of Salmonella spp., especially Salmonella Typhi, between individuals foraging in the rubbish dump and the steppe, but not in the prevalence of Chlamydia psittaci. The pathogens isolated from black vultures may impact their health status but could also have health impacts in other bird species and even humans. In fact, Salmonella Typhi can cause severe disease in humans leading to death. Our results are globally relevant given that bacterial infections from rubbish dumps may affect different species exploiting these sites around the world. There is a need to better control pathogens in rubbish dumps to avoid the risk of infecting wildlife, which could act as potential dispersers and reservoirs of these pathogens.
