Probably metal detecting.
I don't do it very often. I think it's fun to find random things in the forest. I usualy find cans or bottle tops. Sometimes I find cooler things like bullets in the middle of the forest. That probably means that a battle happened there during the war or it's just from hunters. Interesting stuff.
Well, I don't usually tell people what I do for my day job but I'm literally a ninja. Or I tell myself I'm a ninja. But I'm more akin to a stalker lol. Like, no joke, I have to be really good at hiding and concealing myself and I watch people all day. And it translates to daily life in really weird ways. I'm a pretty big person but I sneak up on people a lot. My girlfriend has threatened to put a bell on me because I scare her every time I pop up in our room.
I like to toot my flutes sometimes, but not very good at fingering though.
See~ 
my go-to instruments. (not really flutes but recorders)
I'm a pretty boring person lol but I have a musical background! I'm sadly not a good singer or anything but I played flute for 8 years and I currently play the ukulele. I write my own songs sometimes, and someday I'd like to learn to play piano~
I can bend my whole left thumb to reach the back of my arm near the wrist. And I can call or confuse certain cats by meowing. Does that count?
I'm usually withdrawn and usually watch myself a lot especially in front of older people in a setting I'm not comfortable with. I cannot say I'm talented on this, but acting kind of shows people a different side I can't normally show. Like a type of controlled lashing out. Again, not talented on this, but I kind of liked dancing and being laughed at a lot by most people I know for having two left feet pushed me to try better when I was given a lot of time. At two years of building a dancing habit, some people would get surprised because the idea goes against what my image is like.
I crochet and knit! I was so excited when I did my first cabled knit hat!!! I want to get into embroidery/cross stitch but I don't have the time for more hobbies right now. I haven't even picked up my knitting needles in months 
I write comics.
Also I am obscenely good at Mario Kart Double Dash while playing with me feet. I can beat almost all casual karters and quite a few more intense people. Always a fun party trick. Don't ask how many hours it took, had a lot of time on my hands in university.
I'm fairly quiet and reserved in person and a lot of people mistake that for being shy (I used to be shy as a kid, but I think I've gotten over my social issues as an adult and really just prefer to keep to myself). Most people who know me might be aware that I know how to draw but what they might find surprising is that I enjoy performing on stage - stand-up and improv comedy, to be specific. I never got further than open-mics and small improv shows and with the pandemic that part of my life has kind of been put on hold indefinitely.
Sometime last year I was talking with some fellow performers that I was having trouble deciding whether to focus my attention on pursuing visual arts, writing, or comedy and one of them said "You know, I heard about this new thing that actually involves all three!" I responded with "Making a comic is too much trouble for me."
Not sure if this one's a random talent, but my parents and former classmates used to say so.
I can actually type fast without looking at the keyboard as long as it has tactile bumps on the letters J and F. I'm a horrible typist if those bumps are missing. I guess typing for a long time with those bumps actually helped me gain muscle memory.
Well if its about my random hobby than i love to play guitar, basketball and collecting kabuki noh mask.
Honestly, it fits my persona if you know my art and whatnot but I'm obsessed with moths. Watching moths, taking pics of them, learning about the different species, etc. Yeah. 
I'm an artist/writer that powerlifts, enjoys running 5ks, can solve a rubiks cube and plays magic the gathering at a reasonably high level, watches anime and enjoys traveling to other countries (pre covid). That whole pocket-protector nerd and dumb gym rat archetypes have been dying for a decade and a half
I do contact juggling. You know, the thing Jareth the Goblin King does in the movie Labyrinth. Only that I'm nowhere near as good and I'm still trying to learn how to make my practice ball roll smoothly from one hand to the other without making it fall :'D
Other than that, I make resin stuff:
And also collect/paint BJDs:
I'm pretty sure this is a little odd and not a talent or a hobby, just an odd quirk. I generally like sleeping on the floor. I do have a very thin mattress and blankets and stuff like duh. The reason I do it is odd and many people would be like, you a weeb but I digress. J I wake up much faster to my alarm clock when I'm on the floor. Other odd hobbies I guess would be, goin. Japanese use tatami mats and futons to sleep so it cuts the need for a bedframe and in general I love Japanese culture and would love to move there. This would be me just getting used to sleeping on a thin mattress if I move into a traditional Japanese home. I also do the tea ritual on some occasions.
Also I carry my blanket around the entirety of the house throughout the entirety of the day.
