'Dem Dry Bones' gonna rise again!

We've an owl in our habitat. We haven't seen it around, but it does rotate around roosting locations. We haven't seen the owl since Nov. 3rd. This was the photo. 

Just because we haven't seen or heard it, doesn't mean it has gone elsewhere. I keep looking for the white owl poop called 'mute.' I found some Dec. 16th!


For those inclined to be grossed out, I find that there is no smell. It is far less gross than cat or kid throw ups. It is just bones and fur, and have been through stomach acids. Owl digestion is interesting:
The first part is the stomach  (proventriculus), which produces enzymes, acids, and mucus that begin the process of digestion. 
The second part is the muscular stomach, called the ventriculus, or gizzard. It serves as a filter, holding back insolubles: bones, fur, teeth and feathers (more about this here).

It is best to dry the pellet first. It sat in a dish for a few days. Putting it on the heater, I'd forgotten where it was! (Don't tell the kids. We're not failing!) 

 It was massive. They are normally half this size. Previously I'd found 5 rodent skulls in 3 pellets (Jan., 2019), but this was a find.

I began picking it apart, after it dried out, using my reptile tweezers. The fur is amazingly compacted in the skulls, and around the bones. I could make a whole new vole out of it all! 

Look at the little teeth! It looks like three skulls.


That was the highlight of my day. Happily, we've critters on the cameras.

 I was working on a suet ball, but that didn't happen. I took the container down to the forest. The fisher quite liked it.

Out front, I think this is a bat! They hibernate, but our temperatures have been upsy downsy.

We had lunch in Smiths Falls, after having returned the sink drain to Rona. More on that later! I celebrated actually eating out, and getting out of the house.

You would have been an excellent Anatomy and Physiology instructor, but humans aren't as interesting! Linda in Kansas, with the occasional buffalo skull on the plains.

Hello,
Love your critters and the owl photo.
I heard an owl one day last week, it sounded so loud but still a good distance away. People are still having bear sightings around my neighborhood.
Take care, have a happy day!

Eddie and I heard an owl the other evening, but alas could not see it!

All the best Jan

That was his Christmas Feast to surpass all other meals. Biology, Anatomy ? You are a whizz at all of this. Keep warm, Friday, -2, -11 overnight then on the 25th you reach a mighty 5C.!!! This is according to Yr.no.

You get fascinating animals in your area. Excellent info on the owl too, cool to see the bat fly through. Thoroughly enjoyed all. Thank you Jenn!

the pellets tell a detailed story.

Neat owl pellet dissection.

One of my favorite things to do with my kids, then my grandkids was to hunt owl pellets and take them apart.
We also hunted the forest to find bones and skulls out of curiosity.
Love it!

Were you a scientist in a previous life? Because you certainly one now -- filled with curiosity about the natural world. I love it! Alas... sink problems! No!

Love seeing the inside of the owl pellet:)

Kay said...

Wow! Those owl pellets are truly fascinating. Being able to turn your head all around is also incredibly amazing too.

Fascinating! I liked seeing what all that owl has been eating :)

Good to have an owl around.
