Jefferson Shank Posted March 1, 2020 Share Posted March 1, 2020 Actually about 1.25-1.5 years of age That's why I said "Immature" not juvenile. Link to comment Share on other sites More sharing options...

They don't become "immatures" until they start conducting their 2nd prebasic molt. That molt, depending upon where it was produced, could start soon; certainly in the next couple months. We can see that this individual has not started dropping flight feathers, so until then, it's a juvenile. https://cobirds.org/CFO/ColoradoBirds/InTheScope/87.pdf 1 Link to comment Share on other sites More sharing options...

Learned something new today! Thanks! Edited March 1, 2020 by Jefferson Shank 1 Link to comment Share on other sites More sharing options...
