you cant count a bird if it was ringed that day? that werid it just as wild as that day then the day afther that
Yeah, this is the official ruling in a lot of European countries - as far as I've been able to figure out, this has a few main reasons:
1) The safety and welfare of the bird: allowing people to count the bird while it is in the hand or immediately after release could allow for the bird being held for a lot longer than necessary (for example: "my friend will be here in 20 minutes, could you wait for releasing it until they arrive?")
2) The privacy and work efficiency of the ringers: some ringing stations, definitely in migrant hotspots get rarities pretty much daily, if all of those stations would constantly be flooded with twitchers waiting for a rarity to show up they could no longer ring birds effectively. By only making birds countable the day after ringing, ringing stations have time to prepare for a lot of people coming the next day.
3) Unfair advantages for people that know ringers: some vagrants (mainly warblers) are all fairly regularly captured by banding stations but only very rarely encountered in the field in Northwestern Europe. This is for a few main reasons: they're very skulky, they're very hard to identify, and they're very scarce in numbers. Ringing stations often play song/calls of rare species continuously all night long in hopes of convincing them to come down, and thus create situations where birds that are normally almost never seen can be captured multiple times a year. This isn't really a natural situation at all because the birds are directly called in even though they would otherwise migrate over, and twitchers that are good friends with people in otherwise inaccessible ringing stations would have a huge advantage over everybody else if they could count them as wild.
There's a few other reasons I've heard of as well (among others that ringing just isn't really within the spirit of birding because it simplifies identification immensely), but overall in my opinion waiting until the next morning for a bird to become countable is a fairly good solution for the "official" birding competition where everyone is competing against each other for the best year list, life list, etc. It makes it so that these birds (that are on migration and only came down because they heard the song being played) have a chance to move on before any birder gets to see them, it makes it so that ringing stations aren't overrun by twitchers, and it evens out the playing field so that everyone has equal chances competitively.
Personally I'm not that bothered, and everyone does what they want for a personal list. If I only saw a bird while it was being held (or only immediately after, when it dives in a bush not to be seen again) I don't think I would count it - the bird isn't really displaying any natural behaviour then and is by all meanings of the word still "captive", or at least still has direct effects of being held "captive". On the other hand, if I saw a bird on the same day, a few hours after it was ringed and after it had resumed normal natural behaviour I think I wouldn't have any problems counting it then - as you say, they're still wild birds.
