San Miguel Island is an isolated island located off the coast of California. It is a unique habitat for many different species of birds. The island’s diverse landscape, consisting of beaches, cliffs, and valleys, offers a variety of habitats for the resident and migratory bird species.
From seabirds like Western Gulls and Brown Pelicans to inland species like the Island Scrub-Jay, San Miguel Island is a paradise for birdwatchers. The island’s location and isolation make it an important stopover for migrating birds on their seasonal journey.
In this article, we will explore the fascinating world of birds that inhabit San Miguel Island and why it is significant to conservation efforts.
1. Rock Dove
Rock dove, also known as Rock Pigeon or Common Pigeon, is a member of the bird family Columbidae.
It is considered to be an important creature worldwide due to its domestication by humans centuries ago; resulting in the modern-day Domestic pigeon which descends from this species.
Its population has increased over time because some domestic pigeons have escaped captivity and joined wild populations.
The rock dove can most easily be identified by its prominent blue-grey feathers with darker bars on wings and tail along with two black bands on each wing.
They are typically found in large flocks near cliffs or buildings but may also inhabit rural habitats such as open fields and meadows if there’s enough food available for them nearby.
Although they don’t migrate far distances like other birds, their numbers increase significantly during winter months.
When more food sources become available closeby so that they won’t need to travel too far away from home base for nourishment.Scientific classification:

4. Cattle Egret
The Cattle Egret is a heron of the family Ardeidae found around the world in tropical, subtropical and warm temperate areas. It has two subspecies: western cattle egret and eastern cattle egret.
They have white plumage with buff plumes on their head, neck and back. The beak is yellowish-orange with black tip while legs are orange or yellow coloured depending on species variation.
This bird usually feeds near large herds of animals such as cows, horses etc., where it finds plenty of insects to eat like grasshoppers, crickets etc..
Its presence benefits these animals by removing ectoparasites from them which leads to healthier livestock population.
It nests colonially in trees or shrubs located close to water bodies during breeding season which generally takes place between March-June every year.Scientific classification:
