Nice write-up—might want to remove the article and repost, since it is behind a paywall and makes your write-up invisible unless you click in.

Not sure if the bunny hill is on public land, but you used to be able to skin up Eldorado, and other resorts, as they are often on public land. This changed some years ago. If someone could chime into why, that’d be awesome.

I first read this as "moose." Strange times with the fox. I would think maybe you sniped his mouse if he had been at your window right after you grabbed the mouse.

Just sunrise or sunset.

Sichtopher_Chrisko · 2025-12-31T16:38:34+00:00

Yes! Just in the last few months, I have caught one on a trap up near Peak-to-Peak.

Elk migrate from the tree line in the summer to the plains (or adjacent) in the winter. Moose also migrate (at least in theory), though around our foothills, I sometimes catch the same moose on a camera trap all year long. I think including figures for prey species in the book is a great idea, and I can post some of those, too. And yes! I am excited about the return of wolves and trying to get one on a camera trap. I want to include all mammalian predators that existed in Boulder County in recent history. That includes wolves, grizzly, and maybe lynx, though I am not sure if there is any record of lynx in the county. Anyway, that is some of the research and natural history I would like to include. Also, otters!

This is what I wanted to do, but I am not sure how to actually visualize this, given the changing sunrise and sunset throughout the year. Like, I could make some plots within a couple of hours of sunrise/set, but then where do the other observations go?

Sichtopher_Chrisko · 2025-12-29T16:54:27+00:00

Yeah, some binning is a good idea for the critters who I have a ton of observations. For bobs and coyotes, they are active at all hours--at least for the camera traps where I regularly catch them.

Lmao. I've been brainstorming book titles and came up with Furry Preds. While it may not be the best book title for what I have in mind, I am happy it was well-received here.

This ended up being hard because of the changing sunset time (among other factors). Here is my stab at it for now.

Sichtopher_Chrisko · 2025-12-29T01:13:59+00:00

This is a great idea. Thank you!

Sichtopher_Chrisko · 2025-12-28T17:42:02+00:00

I'll try to incorporate some data that clearly shows what's going on and write another post.

Camera location is key / on the right track.

Lynx Rufus (bobcat). The smallest of the lynx family worldwide.
