Jackdaws, buzzards and great egrets

This video from England says about itself:

5 February 2014

Researchers in Cambridge and Exeter have discovered that jackdaws use their eyes to communicate with each other — the first time this has been shown in non-primates.

While what humans do with their eyes has been well studied, we know almost nothing about whether birds communicate with members of the same species with their eyes.

The new study, published today in Biology Letters, shows that jackdaw eyes are used as a warning signal to successfully deter competitors from coming near their nest boxes.

Today, near the railway station, at the same spot as yesterday, a jackdaw couple. Probably the same birds as yesterday. Like yesterday one of the two jackdaws had nesting material in its bill.

As the train passed Naardermeer nature reserve, a male and a female buzzard circling around each other in the air.

Also at the Naardermeer, two great egrets.

Near the bridge, a coot still sitting on its nest.
