I sent an e-mail to the Peregrine organization which maintains the condor registry. I got a response early Monday morning advising me that Y0 was born on March 11, 2019 in Oregon (presumably at the Portland Zoo, like one of the others I had seen last week). There was no release date provided so I don’t know how long it has been “out and about”. There is another release of “new” condors scheduled for late September at Vermilion Cliffs and it can be viewed online. Check the Peregrine Fund website for details.
