In my post published earlier this morning I wrote about Great Horned Owl variations in plumage color … often called “phases” or “morphs”. While I’m sure most birders understand the concept, it can be helpful to see the different variations next to each other.

First in this post you have the “Desert or Southwest Phase” Great Horned Owl which I saw yesterday afternoon in the Sonoran Desert a bit north of Tucson. Here is that bird and its grayish / white feather colorations which tends to match its habitat found in the desert

Second I present the “Arctic Phase” Great Horned Owl which tends to be found in the northern Canadian Boreal Forest I saw this owl and its youngster during the June of 2023 in Alberta. This owl’s feathers are more white which helps for winter camouflage during that long season of the year.

In closing here is my own “Boreal Forest Phase” Great Horned Owl which tends to be the most common in North America, and helps the owl blend in with its forest habitat.  This bird is the female Great Horned Owl that has nested six years straight near my home in northern Minnesota. You will note this owl’s feather coloration is much more brown and gray. Note how the coloration blends with the white pine tree in which it is perched.
