I found these pellets (not poop, and most likely from an owl) on my driveway yesterday. Thanks to the many trees, we have a lot of owls in the neighbourhood.
When the rabbit, mouse, or rat populations get too high, the owls show up in greater numbers and stay until those populations are down again.
By the way, did you know that while rats and mice belong to the order rodentia, rabbits do not? They belong to the lagamorpha order.
You might think that owls are greedy, eating the whole animal from head to toe (and they literally do start at the head), but they have it all figured out. The crunched up fur, bones, and claws are cast out in pellet form. In plain English, they throw up the parts they don’t want to digest. This is sometimes called casting.
In the pellets below you can see that the owl probably ate something with gray fur. A few bits of bone are showing in one of the top left pellets.
If you think this is a rather disgusting way to eat, consider how we might tackle a piece of meat with our knife and fork. We cut around the bone and we cut away pieces of fat and gristle. The owl, lacking a knife and fork just does this job in a different way, but the result is the same. The unpalatable parts are discarded.
You might not give a hoot about this info, but owl bet you learned something. 😉
