What actually is a Darvic ring please? (1 Viewer)

[Richard]

Could any one tell me what a Darvic ring is please? Is it a particular type of ring? Is it a place or an area?

Thank you

Richard

Darvics are numbered plastic rings which are read in the field, for example on Mute Swans. The name comes from the Darvic PVC sheeting used to make the rings. They were considered virtually indistructible but I head theat older Darvics (exposed to water and air, getting a bit brittle) were likely to shatter if hit by shotgun pellets.

Thanks Touty,

That's an interesting link. There is a White Stork in Nottinghamshire which has a Darvic ring. According to the bird news services the bird was ringed in Holland suggesting it is a true vagrant. A friend also told me that the bird must be wild 'because it has a Darvic ring'. I guess the latter statement is not necessarily true.

Would you happen to know where I could go to find out more about where and when the bird was ringed please?

Thanks again

Richard

I think I have seen in the last few days a mention somewhere that the Stork was from an introduction scheme so sounds a bit dodgy to me tickwise.

Can anyone expand on that?

'Tis what I think but several people have told me that the yellow Darvic ring indicates that it was ringed in Holland as a wild bird. There must be a way of following up on that. At least I know what Darvic means now.

There's been much mention of this Dutch-ringed White Strok, but I must admit I've failed to find out who thinks its Dutch and why! It doesn't have a metal ring, so as far as most would be concerned this isn't a wild bird.

One naughty English ringer many moons ago began to put the Darvic ring OVER the metal ring ... (name ring any bells, Mark? :-O ). He was soon politely asked to stop doing it 'cos we had to take the Darvic off to read the BTO one.

Wouldn't be the first we have had in Notts!

Do you have a contact there so that I can ask which colours and numbers they are using?

Thanks
