Silver Gull
The Silver Gull is a species of gull found around Australia and New Zealand. It is the most common gull in Australia, where it is simply known as "seagull".
Silver Gulls have an incredibly varied diet. They scavenge food from dumps and parking lot refuse. They hunt for fish and marine invertebrates. They forage for seeds and berries. They eat insects, eggs, and more. They are opportunistic feeders and may even steal food from terns, pelicans, and other birds.
Silver Gulls are found in all states of Australia and their population trend is increasing as of December 2014.

Conservation
The Silver Gull is listed as Least Concern on the IUCN Red List and was last assessed in 2014 by BirdLife International. This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
