Friday Feb 26th.
On the return trip from viewing the migratory waders at the hide tide roost at
Toorbul Pt, nth of Brisbane, I and my companion saw 4 Brolgas in the cow
paddock near a local dam enroute towards the Bruce Hwy.
I believe that 3 have normally been in the area but now there are 4.
My question to the more learned Birding -Aus reader is:
What would explain the following behaviour?
One Brolga was grazing far away from the other 3. Suddenly a Brolga leading 2
others started moving quickly towards the single bird. After a running start
the pursued and the pursuer took to flight. The "rear guard" pecked at the
front bird. They did a circle over us and then landed, whereupon this occurred
again including pecking attempt. Then they both landed near the grounded 2 and
clustered as a group of 4. No offensive/defensive behaviour. Two birds started
head bobbing, raised their long beaks simultaneously and gave a long Brolga
call. No more fuss or action. All four carried grazing like a happy family.
"What was that?" we said to each other.
Any thoughts?
Happy Birding,
Burney
