One of the first things that overwhelms you when arriving on Thacher Island is the sheer number of gulls—and the constant squawking that comes with them. They start around 4 a.m. and don’t let up until about 10 at night.
There are two main types of gulls on the island: the herring gull and the great black-backed gull.

As noisy and aggressive as they can be, it’s important to remember—we’re the visitors here. This is their natural habitat.
Over time, you begin to recognize their behavior and patterns. When we arrive for the season, most of the chicks have already hatched, though occasionally we’ll see a mother still sitting on an egg.
If a mama us sitting on an egg, she will vigorously protect the egg and squawk at you to stay away or swoop down at you if you’re close to her baby.
Just as there is new life on the island, there’s also death. It’s not unusual to come across a dead gull along a trail.
By the next day, all that’s left is a pile of feathers—evidence of how quickly scavengers, often other gulls, take over.
Watching them fight and steal from each other, you start to realize that gulls aren’t just loud—they can be downright mean.
