This is a video of two black-necked grebes in the Netherlands.
Before arriving there: two adult black swans with young, near the Valkenburgse meer.
Immediately after the Kikkervalleien entrance: two black-necked grebes swimming.
A lady working for the nature reserve shows us a very young natterjack toad, which was a tadpole not long ago. Also many still very small common frogs. Later, also an adult common toad there. There are also invertebrates in the water here, including great pond snails.
A bit higher, not so close to the water: scarlet pimpernel flowers.
Orchids of Zwanenwater reserve: here.
Many great cormorants flying overhead.
On the water’s edge of a small shallow dune lake, many very small common frogs. Swimming in the water: their brothers and sisters, still in the tadpole phase.
A bit higher, in the dunes: star gentian flowers.
When we get back to the entrance, a black-necked grebe swimming at the same spot where we have seen it earlier.
Slavonian and Black-necked Grebes are superficially very similar in their black-and-white winter plumage, and structural features are important in their separation: here.
