Preening

Gathering mud for the nest

It was easy for the parakeet to extract the seeds from the cotton-like substance of the fruit of the silf floss tree since its leathery cover had already been removed. We can see how it peels the seed and drops the shell.

The first fo the season

When we reached the river coast there were several great grebes scatteres along the coast. To one side I counted 10 and to the other there were as many.

Several females with a white-winged coot preening
