Distribution and Trends in Kelp Gull (Larus dominicanus) Coastal Breeding Populations in South America

Introduction: A Historical Perspective on Trends in Some Gulls in Eastern North America, with Reference to Other Regions

“…A second path to understanding the current North American declines is to compare the life histories and ecology of Herring and Great Black-backed gulls with other species of Laridae. This Special Publication includes status reports for the Kelp Gull (L. dominicanus), which is thriving in both South Africa (Whittington et al 2016) and South America (Yorio et al 2016), and for the Ring-billed Gull (L. delawarensis), which shares a range with Herring and Great Black-backed gulls and is facing a similar decline at least in northeastern North America (Giroux et al 2016).…”

First records of Gray-hooded Gull, Chroicocephalus cirrocephalus (Vieillot, 1818) (Charadriiformes, Laridae), in the state of Espírito Santo, Brazil

“…In Argentina, population growth and range expansion of Kelp Gull, Larus dominicanus Lichtenstein, 1823, was observed on the coast of northern Patagonia and was possibly linked to anthropogenic food resources (Lisnizer et al 2011). However, there is no confirmation that Kelp Gulls have expanded their breeding range in South America as a whole (Yorio et al 2016). Additional studies are necessary to comprehend whether Grayhooded Gull and other gull species in South America are expanding their ranges and to investigate the possible causes.…”

Occurrence and Quantification of Antimicrobial Resistance Genes in the Gastrointestinal Microbiome of Two Wild Seabird Species With Contrasting Behaviors

“…In accordance with our hypothesis, kelp gulls presented higher occurrence and load of ARGs than Magellanic penguins, findings that may potentially be influenced by the contrasting behaviors of these two seabird species in regard to feeding niches, interaction with human-impacted areas and dispersal. The kelp gull is the most widespread and abundant gull species in the Southern Hemisphere (38)(39)(40). Like other gull species, kelp gulls are extremely opportunistic and generalist feeders, very adapted to exploiting a wide variety of human-impacted and highly populated areas, and food subsidies (e.g., fishing discards and (48,49), storks (50), and vultures (49)].…”
