with respect to all who've posted, am I the only one thinking we've possibly talked this one into the ground?
come on, none of us can say 100% where UK EO's are from, but I'm betting we're all in agreement that a bloody large percentage are escapees or released by fed-up owners ... against that backdrop, anyone wishing to further the cause of wild occuring EO's in the UK (or bird/s from the re-intro near continent population) is going to have to come up with the goods, or they are pishing into the wind ... there's too much contention to expect the RSPB, BOU or anyone else for that matter to be falling into the 'expansion into the UK' theory just yet (though of course some do) ... that may change, maybe some glorious morsel of undisputed fact will come to light, maybe they have or will expand into the UK, assumption is just assumption ...
None of us appear to really know what the figures are of birds/pairs at large in the UK (1 pair bred, 2 pairs bred, 3 pairs bred, 11 breeding pairs, 40 pairs, many escapes) or at least I'm certainly more than a little confused by some of the numbers I've seen that don't add up to what's on the official breeding record, do these reports of 40 'pairs' constitute a paired male and female, or simply two birds in the same area? am I repeating myself? yes ... are people just going out and locating EO's and not bothering to submit the record?
We also know that the authorities aren't going to be shooting EO's and are in fact keeping an eye on however many they know about (?) so that IF it came to pass that EO was having a detrimental effect, something more reasonable could be done ... the shooting issue doesn't exist although I dare say there are many that would shoot one.
all the arguments about the UK being conducive to EO biogeographically are of course valid, but pointing out that bones from the Pleistocene exist means nothing ... no doubt they'd do well if the gene pool is healthy enough combined with the few (if any) limiting factors the UK would present EO's ...
what's the problem?
for those worried about negative impacts ... watch out for monitoring results, feed whatever info you personally hold to those that need to know, shed some light ... whether EO's turn out to be relatively 'benign' in the UK than the studies should show that, if not then so be it ...
as for ticking, that's for everybody to decide for themselves ...
