Juvenile Nankeen Night-Herons on the Molonglo

[Con Boekel <>]

The NKNH youngster at Giralang Pond looked very young to me which seems to suggest that it was raised locally - possibly on the island in the Pond. The JWNR trio seem to be more mature and physically they could have flown in from elsewhere. The only straw in the wind is that they seem to behave a little bit like siblings - a very little bit. This suggests that the too may have been raised locally.

Not at all sure about either proposition.

Looking at the 'Movements' section for this species in HANZAB the first words are "Poorly understood" which are I think HANZAB-speak for "Anyone gotta grant for a post-doc?".  However they specifically mention "dispersive movement from drying swamps of Murray- Darling...." and give other examples of birds moving from Victoria to Darwin and birds turning up in NZ and Christmas Island.

So my guess is they've a good breeding season out West, the cornucopia out there is running a tad empty and they've heard of the bounty out this way.

Apparently there are still two at Jerra Wetlands this morning, and I came across two more at West Belconnen Ponds. Where are they coming from? Where are their parents?
