Hello birdgirls,
I see from Google Earth that Bilbao is near the northern coast of Spain, close to the corner where it joins France.
Pigeons racing northerly to Britain set out from Barcelona, not so close to you.
I see that the airport of Bilbao is named La Paloma, which means "pigeon" or "dove" in Spanish, so apparently someone there liked pigeons at one time.
One of my neighbor ladies, Fr. Brunner, here in Cologne, started an animal shelter somewhere in Spain years ago, and the local city kept it going. I met her when I took over bird-sitting a beautiful pigeon she found exhausted on the roof of a car, with a broken wing, on which she spent a lot of money at the vet's. I will try to contact her when she is home to see if she has any advice for Spanish contacts. Probably not, but doesn't hurt to check.
I'm from Texas, living in Cologne. If you would care to PM (Private Message) or email me your phone number, I can call Bilbao for 0,015 Euro or 1-2 cents a minute from here. Same time zone as yours. I sleep late, until noon-ish.
Keep pigeon warm, as you know. If it has nerve damage, drinking water might be dangerous. But it does need to stay hydrated. Resources section lists IRS International Rehydrating Solution formula. Pigeons drink like horses from a water trough, heads down, beaks in water. Opening to the trachea or windpipe is at the base of the tongue, on the topside; not near the roof of the mouth.
I rescued a pigeon last June, Mister Fifty, with PMV (ParaMyxoVirus). If he tried to pick up a seed it would throw its head up and toss te seed any which way, and would push its legs straight, effectively pushing itself upwards and backwards, and flapping its wings at the same time, so that it looked like it was flying backwards a few feet. Imagine yourself on a diving board wanting to do a swan dive, but doing a back flip instead, and you get something of the picture. He tried to pick up a seed, but would hit the ground near the seed. If he wanted to see what was behind and above him, he had to turn his head upside down. I kept him in a quiet, dark, pet carrier at first, where he felt safe; force fed him and used a hypodermic syringe with a baby bird feeding needle (curved needle with a blunt, bulbous tip) for water and medications, and after five weeks with us he flew off to chase te local females. His voice changed while he was with us. My wife saw him a few months back, acting like a normal healthy male street pigeon. She recognized him partly because he had been scalped before I caught him.
I won't advise you to do this, because I am not an expert on breaks, but if I recall correctly, someone (fp/feral pigeon?) told me back in March that if you pull the wing out gently and the pigeon can retract it, then it is not broken. But I will let someone else advise on that. We have a female pigeon Osk-gurr who was hit by a car or by a raptor whom I rescued on March 20th, who had "soft tissue" damage (to nerve or muscle, and who cannot use her left wing). She had all of her tail feathers missing, many secondary feathers on the left wing missing, and feathers on her upper back from being pecked by other pigeons. Quick on her feet, and very healthy now.
Big question: do you speak Spanish? (I don't, but sister in USA does). There are some PT members who do, such as Victor, if this is necessary to find help.
Even if for some reason she cannot eat on her own, a bowl of seeds and a deep jar (1-2 inches deep) of fresh water in front of her will be a psychological boost.
When you loom over a bird, you are in the predator position. The "Hand" is always an enemy (even to my rescued-as-a-baby and hand-raised two-year-old macho male pigeon Wieteke). I know you know this, but even I tend to forget this at times, all too often. It is always much more convenient to have them on your lap or on a table when you handle them, and they are often scared stiff and very, very vulnerable. I need to work on my care-taking skills and attitude.
