Reduction of garbage in the diet of nonbreeding glaucous gulls corresponding to a change in waste management Reduction of garbage in the diet of nonbreeding glaucous gulls corresponding to a change in waste management
Glaucous gulls (Larus hyperboreus) are major predators in the Arctic and may benefit from human development. We studied use of garbage by glaucous gulls in Barrow, Alaska, in 2007, when municipal waste was disposed of in a landfill, and in 2008, when it was incinerated. In both years, diet samples from breeding adult gulls contained less garbage than those from loafing nonbreeding gulls...

Does garbage in diet improve Glaucous Gull reproductive output? Does garbage in diet improve Glaucous Gull reproductive output?
Anthropogenic subsidies are used by a variety of predators in areas developed for human use or residence. If subsidies promote population growth, these predators can have a negative effect on local prey species. The Glaucous Gull (Larus hyperboreus) is an abundant predator in northern Alaska that is believed to benefit from garbage as a supplemental food source, but this supposition has...
