ah, I thought it'd be a little more complicated! I suppose the top breeders could provide an anon contact.
Would be easy to add a 'last seen' feature for birds that are presumed to be resting and not contained. We're still just feeding her and leaving her to roost, she seems happy enough, although we saw a hawk take out an adult blackbird in the garden (which is pretty much open moor) a couple of weeks ago, so that's a concern. Plus the weathers a little tricky at the moment.
The union have got in touch but are communicating by post. We have been given the owners full name and address, but no contact telephone, which is pretty pointless (we could send it back pigeon post, I suppose ;D ) and doesn't really protect the owner from the scenario you described above. Letter says the owner has been given our address and will correspond in due course. I assume they have been provided our telephone number as well, but don't know.
it's been fed on standard mixed bird seed for about three days, is this okay for them?
