yo people, i have 2 parakeets called fernandez and lopez

i've had them for 1 and a half years now

i got htem both at petco from the bin o budgies

they are quite tame, they will come onto anyone's finger if you put your finger in front of them

but it's hard to play with them and take them outside because they always fly back when you move hand away from perch

once you get them out,they fly around a lot in my room and smash into things and stuff, and they always fly back to top of cage, if i cover the cage completely with a towel, they fly onto the blinds of the window,

once i put them back on my shoulder, which is the only place they seem to want to be, they'll fly back within 30 seconds

how can i make them more playful? thanks
