Thanks for the mammaries.
A Saturday Squirrel feature I posted a couple months ago seemed to draw excitement from everyone that my backyard may soon be overrun with squirrel babies. While I have yet to see any little ones romping around on my lawn, I did get a big surprise when I uploaded the photos I took of some squirrel activity this past Tuesday. Above is the very first picture from that set. Do you see what I see?
Here’s another photo of the same squirrel on the ground:
My modesty demands taller grass!
Yes, this squirrel’s not only flashing nipples, but she’s quite obviously actively nursing! Notice the condition of the fur on her backside and at the base of her tail. Somewhere in 
the vicinity, there are most definitely some little squirrels! I’m not so sure that location is my tree, as this squirrel’s fur pattern is very dark and splotchy compared to most of the critters I normally see in my yard, and I don’t recall it from any of my past viewings. But nevertheless, there’s a nursery somewhere within the range of my camera!
While doing some research on the subject of squirrels and their privates, I came across this excellent reference from a blog dedicated to The University of Washington’s squirrel population. I love how most college campuses treat their resident squirrels like royalty!
Anyway, from the UW squirrel blog post I linked to….
Their (squirrels’) gender is most obvious during breeding season, when you can see male squirrels’ testicles and females have prominent nipples with which to feed their babies. During the breeding seasons, from December to January, and May to June, if you find a squirrel without testicles, it is definitely a female. During the non-breeding seasons, unless you are able to feel around, the gender could go either way. When it isn’t breeding season, males carry their testicles inside their bodies. When it is breeding season, their testicles enlarge and become exposed.
So there you have it! It is breeding season, and I have a squirrel lingering around with prominent nipples! I’ll be on the lookout for any signs of squirrelets!
Oh, and as to that other gender’s prominent trait that’s mentioned there….. well…….
Happy Father’s Day to all you nutty Dads out there!!!
Have a fantastic weekend everyone!
Evil Squirrel's Nest 
Do I need to add you to my list? The one of blogs that I have to watch out “liking” posts because of the image that ends up being featured? Squirrels gone wild(er) .
LOL! I noticed that on your sidebar… you can either hope that the more unobtrusive mother gets displayed, or you’ll quickly have to find 10 other posts to like! 🙂
😀
I appreciate UW giving guidance in case we can’t just feel around. I think there are laws against that type of thing.
Aw, what squirrel wouldn’t appreciate getting a little feel up now and then? 😉
Very interesting. Hope you get to see baby squirrels!
I’m hopeful too! From what I read on the UW blog though, by the time they venture from the nest, they’d be hard to differentiate from adult squirrels….

think that testicle-thingy we all have in common with the squirrels :o)
Yeah, I hide mine when it isn’t breeding season too… 😀
Great photos. I do hope we get to see some juniors. 😀
I’ll look for squirrels wearing beanies and carrying slingshots….
Would be sweet to see some baby squirrels. Would be even better if they were reds and not greys… 😉
I’d love to see some red squirrels in my backyard! Alas, I think the neighborhood is all grey grey grey….
Plus Reds are native to the UK. Greys over here are rather poorly treated because they’ve taken over rather and the Reds are protected (only the Greys don’t seem to know this and will still beat up the Reds).
