Hi All,
   
Margaret Leggoe  recently had a posting which implied creching by Dusky Moorhen.
Nobody responded, and i am wondering whether there is any mention of it in the literature.
This because i recently watched a group of eight moorchickens in charge of a pair of adults and wondered whether they were a single brood.
 
Today i watched over a period of two hours  nine cootlings still with red-transparent heads being fed almost continuously by two adults.
One gets used to seeing duck families of this size, but waterhen?
--------------------------------------------------
Different topic: does anyone know how large a Rufous Songlark’s territory would be?
Most mornings i walk a fairly linear 1 1/2 kms.
At the start of it there is usually a Rufous Songlark ,
at the end of it likewise and at at least a couple of points along the way.
How many songlarks? How can i tell ?
------------------------------------------------------
And different topic again?
On West Belconnen Pond are three, 3 to 4 month old cygnets in the company of a single adult.
Somebody probably knows their exact age and if i searched amongst my photos
i could figure it out but 3~4 months is close enough.
For ~2 months there has been only one adult accompanying them.
 
47 days ago ‘another”pair started sitting on the same nest.
Last sat-sunday 6 cygnets were hatched.
Today with two parents in charge this family took a tour of the pond.
The 2-parent male proceeding to chase the one parent ( i think female) family at every opportunity.
It actually savaged one of the near adult birds.
Question: is it likely that one of the new pair is the missing bird from the old pair?
