If you’ve recently spotted a black squirrel in your yard or neighborhood and thought, “What is that species?” you’re not alone. We’ve had many customers asking about these squirrels and why they seem to be showing up more often around Los Gatos. The short answer is they’ve been here for decades and love suburban environments..
What Is a Black Squirrel?
Black squirrels are not a separate species. They are usually a color variation (melanism) of the Eastern Gray Squirrel. Melanism causes an overproduction of dark pigment, resulting in black fur instead of the more familiar gray. Aside from color, black squirrels behave just like gray squirrels:
Same diet
Same nesting habits
Same enthusiasm for bird feeders
Why Are We Seeing Them in Los Gatos Now?
Several factors are likely contributing:
1. Natural range expansion
Eastern Gray Squirrels — including black variants — have been expanding their range for decades. Once established, they adapt extremely well to suburban environments like Los Gatos.
2. Genetics + local populations
When a population includes the gene for black fur, it can become more common over time, especially if black squirrels successfully reproduce and thrive.
3. Urban and suburban habitat
Los Gatos offers ideal squirrel habitat with:
Mature trees
Backyards with food sources
Parks and greenbelts
4. High visibility
Black squirrels are simply more noticeable than gray ones. Even a small increase in population can feel dramatic because they stand out so clearly.
What Does This Mean for Birds?
As squirrel populations increase, competition at feeders can increase too, often leaving birds with less access to food. Black squirrels aren’t more aggressive or destructive than gray squirrels, but like all squirrels, they are:
Persistent
Clever
Very interested in bird seed and suet
Feeding Birds Without Feeding Squirrels
One effective, bird-safe solution is hot pepper–treated bird seed and suet. Birds can’t taste the heat from hot peppers, but squirrels, as mammals, find it very unpleasant. This allows birds to feed normally while discouraging squirrels from taking over feeders. It’s a simple way to restore balance without harming wildlife.
A Sign of a Changing Landscape
Seeing black squirrels is a reminder that wildlife is always adapting to changing landscapes. Whether you find them fascinating or frustrating, they’re now part of our local ecosystem, and learning how to coexist helps both birds and people enjoy their outdoor spaces more.
