I don't live there for the entire duration of the year and they have a tendency to be extremely
skittish and prone to tail dropping, but yeah, on occasion back when I was rearing baby birds there and one would happen to be basking I'd successfully offer a nice, juicy worm
Now that I have a baby northern (spoilers, hah. I will make a proper introduction when it's a bit more accustomed to its new home) there will probably be suitable leftovers more often.
There was a big, chill(...ish) male I used to see particularly often on a rock near the front door (they key word here being 'see' as opposed to 'hear panicked skittering of a lizard no longer there'), unfortunately he wasn't present at all this summer so he probably passed already, they sadly don't really live longer than 4-5 years as far as I know.
From what i've observed they have a sedentary lifestyle, they will move around a bit as juvies then pick a big rock/flowerbed/log as main residence and sort of roam around that as their central hub. The territories can overlap. The babies are extremely cute and somewhat more docile.
Taking reptiles from the wild unless maybe it's for rehabilitation purposes is illegal in Poland and highly frowned upon in terraristic circles, even if this one happens to be a very common species. So yeah, no, not really. My main reptile conservation contribution is picking up slowworms (adorable legless lizard) off forest roads before they become regrettable pancakes :')
