Curious

"It's amazing how this park has changed since the first day, the trees are turning different colors. Maybe because of the change in temperature! Anyways, I haven't been observing the birds a lot lately, cause there is a lot more than just birds. Today I saw a hole in the ground, I took a look at it more closely and whatever animal did this has amazing abilities but I wonder what animal did this, maybe a rabbit?" (My field notes 10/18)

 A picture of the hole I observed and took a closer look at. I got closer to the hole I saw a squirrel run it's little feet across the other side. I wonder if squirrels can make holes that deep? 

 I researched if squirrels can dig holes and it turned out to be true. According to the web site http://ucanr.edu/sites/Ground_Squirrel_BMP/Biology/Identifying_Burrows/

Squirrels can dig holes up to three feet deep and four inches in diameter. Many of the squirrels that dig up the holes usually end up leaving them abandon because they either: die, there's lack of food, they found a new area to dig, and invasion of pest species.

 Squrriels dig burrows usually underneath rocks, logs, or other protective structure. Many of these burrows have interconnected systems with multiple entrances and exits, to according the web site Ucanr.edu. 

 All along I thought it was a rabbit hole, but apparently I was wrong. My curiosity, made me learn new things about squirrels I never knew. It's always a good idea to keep your eyes open and always have a curious mind.
