A grebe was nesting
A heron was fishing
The heron got a bit closer than the grebe was comfortable with, so she gave a bit of a warning, which the heron completely ignored. The coot didn't get involved.
The heron was acting completely oblivious to the grebe.
Then things got more intense.
|... he's bigger than I thought|
The heron climbed onto the nest and poked around.
|... a little help?|
The grebe had finally convinced the heron that its presence was unwanted...
... when its mate arrived to give back up.
A few repairs to the nest where the heron had stomped all over it,
a change of shift,
and the disgruntled grebe was able to get off the nest and have a bath.
