The grey gull, Leucophaeus modestus, is also commonly referred to as the garuma gull. This gull is indigenous to South America.
It is a member of the Laridae family and belongs to the Leucophaeus genus. It can be confused with the grey-headed gull, which is a completely different species of the genus Chroicocephalus.
Male and female birds of this species are similar in appearance. Grey gull adults can grow up to 18 in (45.7 cm) in length and can weigh between the range of 13-14 oz (368.5-396.8 g). The color of this bird's head changes with the season!
In the summer season it is white in color, whereas in the winter season, it becomes brownish-grey. The wings and body of the grey gull are grey-colored with the upper side being darker than the underside.
The grey gull inhabits mudflats and sandy beaches along South America's western coasts where it feeds upon mole crabs, fish, nereid worms, and offal. This bird breeds inland in northern Chile's dry Atacama Desert, which is quite unusual for gull birds.
It also occurs across its non-breeding range which comprises much of South America's Pacific coast, namely, Colombia, Costa Rica, Chile, Peru, and Ecuador. It has also been seen in the Falkland Islands, the South Sandwich Islands, and south Georgia.
This bird has a restricted breeding range and its population has been observed to be declining slightly.
However, as it is present in abundant numbers, it has been listed as Least Concern by the IUCN. Keep reading to get to know more about the world of the grey gull!

How to help grey gulls
Grey gulls are listed as a Least Concern species by the IUCN as they are present in abundance. However, these birds face difficulties as a result of storms that cause breeding failures and as a result of a loss of eggs due to predation.
These birds live in a marine ecosystem that is known to be one of the world's most productive ones, leading to them often being disturbed by the activities of humans.
These birds can be conserved by reducing human disturbances in their region. This is how we can help them!
