thanks for your replies - i did contact the owner who said he would collect but on subsequent conversation with others i was informed that the bird would "probably" be euthanized. i did email the owner stating the extent of the bird's injuries & asking for advice etc but received no reply - i also texted. as i mentioned, if i have to keep him then fine however if someone could please answer the question of release or not i would be really grateful. that is, if i do release him what are the chances of him either returning to me, the owner or just getting lost & dying of starvation or predator attack - appreciating it's a question requiring an answer based on speculation. also if i can't release him then what outdoor facilities (and other) would be required to give him a reasonable existence? the little guy's a real fighter so i wouldn't want to give up on him. i live in co. antrim, n.ireland. thanks again.
