Welcome!
Denver Audubon has a newish youth/ teen birding club that has regular trips around the front range. So far we've gone to the Barr Lake bird banding station, attended the Denver Christmas bird count, and most recently a duck trip to south Platte park.
I copied Kate, the community outreach coordinator who can add you to the email list. I also copied Santi (maybe you already know him) who is an active teen member and avid birder in Denver.
There are a few other youth birding clubs around the front range as well. One in Boulder and two college clubs (that I know of) one at CSU and one at CU Boulder.
Feel free to reach out if you have any questions or are in search of connections!
