Do adult Olive-backed Orioles depart ahead of juveniles?

aka DDDs (Departure Date Determinations). When migrants return, we delight in claiming the "First for the season". So why is it that we don't place equal emphasis on claiming the "Last for the season"? Well we all know why. It's too darn hard. Unless we religiously keep a diary of our sightings and then compare notes in the off-season to determine whose was the last sighting, how would we do it? Well now I think I know: provide another avenue for some one-up-manship on a public forum! If you've bettered the last date, please set the record straight ...

Do adult Olive-backed Orioles depart ahead of juveniles?

Post by Mick Atzeni » Fri Apr 11, 2008 4:41 pm

Olive-backed Orioles are a summer breeding migrant (Sep-Apr) in south east Australia.

I'm not sure if this is significant, but yesterday we saw individual immature Olive-backed Orioles at three locations: Murphy's Ck, Highfields Falls and Withcott, but no sign of any adult birds. I'm wondering if anyone else has noted the same thing lately?

Furthermore, will all the immatures eventually depart or do some remain until maturity. Are these what we intermittently see throughout the cooler months?

So take note of the orioles you're seeing lately and let us know if there are any adults around still.

Hello Mick

I just came upon your post. Yes I too noted a group of about 8 immature Olive-backed Orioless at my place on Flagstone Creek. Not an adult among them. This would have been Sunday 30 March. They were feeding on an exotic pine which was endowed with 100s of small purple fruit.

No adults around at the moment. Not sure if the last of the immatures have gone.

Cheers

Immature orioles

Theory's holding up so far. The Olive-backed Oriole in my yard today was an immature bird too.

Immature Orioles on the move?

Post by Mick Atzeni » Thu Mar 26, 2009 10:37 pm

I hadn't seen or heard an Olive-backed Oriole for a couple of months at Upper Lockyer but today saw two birds, both immatures. The presence of only immature birds at this time of year is intriguing.

Is the same phenomenon occurring in your area? Where are the adults at present? Please let me know one way or another.

Adult

Theory rocked today by a sighting of an adult oriole at Abberton, Helidon.

Still maintain the majority are immatures, and you'll be hard pressed to find an adult locally at present.
