If Penfold Park was demolished, where would be their next stop?  :-/

Interesting formation!

But..it seems to me that the "Great Egrets" are too small......when compared to the Little Egrets next to them...

I think the birds in the photo are Cattle Egrets, of which there is usually heavy passage through HK during September.

On a quick second look I think three are either Great or Inter Egrets, the latter probably, this also being a migatn through HK esp. in Sept.

Thanks Mike and dominic!! :)
I could see the cattle egrets now. That's why the "great egrets" are too small!! hahaha... ;D
However, how to distinguish inter from cattle egrets in flight? ???

May be I should also ask here about the identities of the following egrets:

Mai Po Natural Reserve
25/8/2004
EOS 10D, 400/5.6, 1.4X

Are they intermediate egrets?
Their beaks' line stopped under the eye, but the neck looks like a great egret.

I think it is a intermediate egret. :)
Their necks are usually not a reliable factor. :P

Hope to share the three 'necks' with you...

Great Egret: Long, often held straight such that it looks even longer than the body, and always thin.

Intermdiate: Long, often thinner at the top half and quite thick at the bottom half when held straight, with the impression of 'full-chest' when seen from certain angles.

Cattle: Always thick and short for a egret even when held straight.

And wish this all helps a bit in the identification of these very angelical birds seen with such relative ease in Hong Kong that we should all take care to value their presence!
:D

So..the BENT-S shape of the neck is not a distintive character for great egret......
Thanks Koel!

A flock of 70 egrets were flying over Shing Mun River this morning. :D
