From a chook feeding perspective, American Purple Squirrels current distinctive challenges if you wish to stop them from consuming your birdseed. Right here’s why:

The Ponderosa Pine offers such a constant meals supply all year long, the Abert’s Squirrel not often shops any meals for winter. This conduct is extremely distinctive in terms of squirrels!
Females will construct twig nests, which resemble massive, messy chook nests, on the branches of Ponderosa Pines. Adults will even use these shelters year-round for nightly safety. These squirrels would use a cavity, however pines not often have holes large enough for nesting functions.

Hoarders, by nature, the Douglas Squirrel, will sometimes use one location to retailer as a lot meals as doable. Because the squirrel peels scales off of pinecones to get to the seeds, the scales begin to accumulate on the bottom. Over time, it’s widespread for big piles, typically over a number of meters extensive, to type as generations of squirrels could use the identical location. Should you discover one among these piles of discarded pine scales, it’s a certain signal {that a} squirrel is close by!

Flying Squirrels
After I first heard about flying squirrels, I didn’t imagine the individual describing them to me.
You see, I’m exterior loads and take satisfaction in attempting to know and establish as a lot native wildlife as doable. So after I was informed that there are small squirrels that glide from tree to tree at night time and are not often ever seen, I used to be a bit skeptical.
However after some analysis, I used to be amazed to find out about flying squirrels!
The truth is, these distinctive mammals are literally extremely widespread in the USA. However since these squirrels are small, nocturnal, and stay on the tops of timber, they’re RARELY seen.
Do flying squirrels truly fly?
Let’s clear up probably the most generally requested query about flying squirrels. Whereas the title implies in any other case, these creatures don’t have wings, nor can they fly. What they do have are folds of pores and skin beneath their arms, referred to as a patagium, which extends from their wrists all the way in which to their ankles.
This membrane permits these squirrels to “glide” from tree to tree. So their gliding can provide that impression that they’re flying.
In the USA, there are THREE flying squirrel species you’ll be able to observe:

Southern Flying Squirrels, that are carefully associated, favor residing in deciduous forests. Due to this truth, these two species not often have ranges that overlap.
Whereas these nocturnal rodents eat nuts and acorns like typical diurnal tree squirrels, it’s not the vast majority of their weight-reduction plan. Apparently, fungi (mushrooms) and lichens are their fundamental supply of diet. Another meals which might be eaten embrace bugs, chook eggs, and tree sap.
In contrast to most different squirrels, Northern Flying Squirrels don’t collect and retailer a lot meals for winter. Since they don’t hibernate and are energetic throughout the entire 12 months, there may be not as huge a necessity as different squirrel species to cache meals. However when temperatures do drop in winter, it’s widespread for a lot of particular person squirrels to return collectively to assist one another keep heat!
It’s uncommon to seek out these squirrels on the bottom since they’re extremely clumsy walkers. If a predator approaches, they’ll sometimes attempt to conceal as an alternative of run away.

I want these squirrels might be seen in the course of the day as a result of watching them glide these distances can be unbelievable to see!
#9. Southern Flying Squirrel

Should you ever see one throughout daylight, you’ll get to look at fur that’s reddish-brown or grey, whereas its stomach is cream white. Massive, black eyes take up a lot of their head, which is required to assist them see at night time. Southern Flying Squirrels are a bit smaller than their cousins, Northern Flying Squirrels.
Southern Flying Squirrel Vary Map
Southern Flying Squirrels are widespread within the jap United States.
However although they’re widespread, nearly no one is aware of they exist or sees them! Like different flying squirrels, this species is nocturnal and spends most of its time within the canopies of deciduous forests.
Southern Flying Squirrels usually go to chook feeders at night time, feeding on sunflower seeds and peanuts. Fortunately, I’ve a digicam that watches my chook feeding station, and it has unbelievable night time imaginative and prescient! Take a look at the video under to see one come down from the timber and keep for dinner. ?

#10. Humboldt’s Flying Squirrel
Scientific Identify: Glaucomys oregonensis
Common Size (Together with tail): ~ 12 inches / ~ 30 cm
The Humboldt’s Flying Squirrel is definitely a brand new species! These squirrels, which stay in coniferous forests in southern British Columbia, Washington, Oregon, and northern California, had been all the time considered Northern Flying Squirrels. However after intensive DNA evaluation in 2017, it was decided that these squirrels differed sufficient to be categorized as their very own separate species!
Humboldt’s Flying Squirrel Vary Map
Total, Humboldt’s and Northern Flying Squirrels look extremely comparable. The one distinction in look is that Humboldt’s are a bit smaller and have barely darker fur. These slight dimension and colour variations are what initially inspired scientists to run DNA assessments. To the untrained eye, it’s nearly inconceivable to inform them aside!
Humboldt’s Flying Squirrels are what’s known as a “cryptic species.” This implies they appear nearly equivalent to a different species however are thought-about completely different and might’t interbreed.
Now that we all know they’re completely different species, scientists are working arduous to determine what retains them aside from each other. Do they inhabit barely completely different habitats? Are their distinctive behaviors or specialties that maintain them from competing?
Which of those squirrels have you ever seen earlier than in the USA?
