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

Flying Squirrels
Once I first heard about flying squirrels, I didn’t consider the particular person describing them to me.
You see, I’m exterior loads and take delight in making an attempt to know and determine as a lot native wildlife as attainable. So after I was advised that there are small squirrels that glide from tree to tree at evening 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 america. However since these squirrels are small, nocturnal, and dwell on the tops of timber, they’re RARELY seen.
Do flying squirrels truly fly?
Let’s clear up essentially 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, known as a patagium, which extends from their wrists all the way in which to their ankles.

Whereas these nocturnal rodents eat nuts and acorns like typical diurnal tree squirrels, it’s not the vast majority of their food regimen. Apparently, fungi (mushrooms) and lichens are their primary supply of diet. Another meals which might be eaten embody bugs, hen eggs, and tree sap.
Not like most different squirrels, Northern Flying Squirrels don’t collect and retailer a lot meals for winter. Since they don’t hibernate and are lively throughout the entire yr, there may be not as massive 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 come back collectively to assist one another keep heat!

Southern Flying Squirrels are widespread within the jap United States.
However regardless that 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 hen feeders at evening, feeding on sunflower seeds and peanuts.

The Humboldt’s Flying Squirrel is definitely a brand new species!

However after in depth 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 shade variations are what initially inspired scientists to run DNA assessments. To the untrained eye, it’s nearly not possible to inform them aside!
Humboldt’s Flying Squirrels are what’s known as a “cryptic species.” This implies they give the impression of being nearly similar to a different species however are thought of completely different and may’t interbreed.
Now that we all know they’re completely different species, scientists are working onerous 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 america?
