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. Quote 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 Quote Link to comment Share on other sites More sharing options...
