I have my beardie for 9 months now (he's 12 months old now).
Big contrast
I remember him, a slender lizard-like creature, sliding behind its basking branch once I entered the room.
I remember him scratching me up violently and whipping with the tail when I put him into his carrier for the first time.
I remember him freaking out at the sight of me doing normal household chores (that I could not avoid doing in front of him).
And I remember him not daring to take a worm from me. He didn't dare for a long time.
Nowadays he comes towards me when I enter the room or just stays wherever he is in a relaxed manner, he goes into his carrier and doesn't even show stress marks, likes to be pet everywhere on his body, and he loves watching me doing household chores and also things he was very afraid of like the broom, the iron board and clothes on a hanger are absolutely no problem anymore. Such a relaxed, nice beardie
I just always remember how much they have to learn: Learning to trust a human - as an animal that just by the way they live has nothing such as caring parents, or a hunting partner or such, and then it "should" trust another being and one that's so much bigger! For a mammal or bird it's much easier - it might see a human as somebody like a parent, or somebody from their natural social group like their pack, flock...
Then we pick them up, pet them - in nature there is nothing that picks up and touches a reptile with good intention. Whoever does this is a predator, but they learn we do it in a good intention.
In nature nobody would share an insect with him, he would not have parents who feed him or a partner who comes by to share the bounty of the day, and if he would dare taking it away from another lizard, there for sure would be a fight. I'm thinking of: When he eats while being hand-feed, he had learned that it's okay to take away food from me and that "huge strange being" won't be angry!
So for that, I'm really proud of my beardie, and of all those beardies (and other reptiles, other animals) who learn that. They are often not seen as smart, sadly, but learning that requires IMHO a good amount of brain
If they would be just "instinct-driven", they would not be able to do that big adaption.
