In hindsight, eating sand was a bad sign, but it might just as likely passed the sand, waddled back down the beach and started swimming for colder water (or at least out of sight). If it had been 'rescued' in the first couple of days there would probably have been an equal outcry that it should be left to its own devices
That is a very good piont....I would have thought it would have been prudent of DoC to maybe google or even ring around say the LA zoo who I believe have these birds, for advice on that, and the effects of the warm temps, very early...which I think if it had been they would have been told "get that bird into a chiller now".
DoC does have a record of going off on what it thinks, rather than consult experianced people outside DoC for opinions, but does have a record of the grass roots guys consulting "off the record" before getting over ruled from above.
Personal experiance, on more than 1 occassion been rung and visted.
