Weatherfish enemies are northern pikes, hedgehogs, herons …


This video is about European weatherfish, Misgurnus fossilis, mating.

Hedgehogs, rats and herons like eating European weatherfish, which is evident from transmitter research by RAVON. This loach is also high on the menu of the purple heron in the Natura 2000 area Zouweboezem. It was suspected that the northern pike, the main freshwater predator fish, also likes to devour weatherfish, but evidence for this was lacking, until …

Recent research in Hungary (pdf, 0.4 MB) shows that in water with a big weatherfish population, the diet of pikes in the spring may consist for more than 90% of weatherfish. Probably the nocturnal loach, which normally hides during the day, during the reproduction period is easy prey as they swim along the banks by day.

Recently, also in Brabant province in the Netherlands, proof was found of a northern pike eating a weatherfish.

Honey buzzards returning from Africa


This video shows a honey buzzard, digging at a wasps’ nest.

Translated from the Dutch Sovon ornithologists:

Saturday, May 16th, 2015

On May 5, the first bird of the transmitter project ‘Honey Buzzards of the Kempenbroek‘ returned to our country. In the third week of April the birds left their wintering grounds in West Africa. The birds needed more time than usually for the journey due to bad weather over the Sahara and Europe. The coming period we will be able to see if and when the other birds will arrive with us. The Honey Buzzard, along with species such as Turtle Dove, Icterine Warbler, Marsh Warbler, Reed Warbler, Golden Oriole, and Red-backed Shrike is among the last species to return to us from Africa.

Meanwhile, more honey buzzards have arrived.
