Top predators have been proposed as reliable biodiversity signposts, but their role is controversial. Identifying efficient biodiversity indicators is a key pillar of the global conservation strategy. In abundance of arthropods may determine the segregation between non-corvid passerines and scavenger Similarly, inter-specific competition in carrion exploitation as well as a decrease With an increased abundance of invertebrates, and coincided with periods of higher energy demand Thus, their appearance was linked to seasons and conditions Through predation on scavenger arthropods. Non-corvid passerines profited from carrion opportunistically, especially Passerines avoided simultaneous presence with vultures and delayed their attendance toĬarcasses from the time of input. Furthermore, corvids mismatched their presence with vultures,īenefitting through commensalism from the generation of residual small pieces and scraps. Regarding the selection of carcass characteristics (i.e., format, scattering, biomass), the surrounding Individuals of the Corvidaeįamily, recognized facultative scavengers, showed a similar trophic behavior to obligate scavenger raptors Its relationship to other species, and to reveal its ecological implications. The objective of this study was to evaluate the patterns of attendance of passerineīirds, including the non-scavengers, at carrion inputs in order to divulge the importance of this resource, However, carrion is important for otherįacultative scavengers, and even for other non-scavenger species, which may be influenced by the onset of Mainly using scavenger birds and arthropods as study models. Years progress has been made in understanding the scope, implications and value of carrion ecology, Carrion provides energy transfer to food webs as a primary trophic resource for many taxa.Įcological relationships around this pulsed resource are highly complex and are influenced by manyįactors, including those related to its availability and the management of carcasses by humans.
