In  the spawning area we meet spawners as well as their ”satellites”

Members of the LK forum have been interested in what small animals we can see in action in such waters. The information below is provided by Henn Timm from the Estonian University of Life Sciences:

"In the upper reaches of rivers and streams where the flow is rapid and the water is cold there is almost no plankton. The zoobenthos (the animal fauna of the bottom) is dominated by crenobiotic species (invertebrate aquatic organisms living in cold spring waters), for instance unicellular species, crustaceans, insect larvae, leeches, snails … Typical fish species are river trouts and graylings “.

Spawning period is ending

The spawning period is coming to an end in spring-fed water bodies.

This year viewers could see in the webcam, and thanks to the low water level, even the spawning under the ice cover. Unfortunately the water turned more muddy due to the low flow rate, but such a view we have simply not seen in previous years.

Meeting a goshawk in the city no longer rare event

Urban people meet goshawks increasingly often. In winter migrants from the east and north add to the birds that have nested here and so they are even more easily seen.

Why then in the city where they have also started to  nest? Simply in order to catch prey more easily. In winter there is no lack of domestic pigeons or jackdaws and other corvids in cities.
