Distribution patterns of Black-necked Grebes

SchwarzhalstaucherBlack-necked Grebes (Podiceps nigricollis) know how to use favorable conditions surprisingly spontaneously in individual years, as if “scouts” were permanently on the move, which guide other birds to new habitats and locations. One example is the spontaneous emergence of a breeding colony at the Alfsee in the Landkreis (district) Osnabrück in Lower Saxony in June 2011 with 52 pairs which tried to use the favorable conditions through the mass occurrence of emergent water plants. It goes without saying that not all breeding occurrences emerge and disappear so quickly; there are also numerous breeding sites that have been occupied for decades and are often located near colonies of gulls, especially those of the Common Black-headed Gull (Larus ridibundus).

One other example is an occurrence in southern Brandenburg. In a vast shallow lake area, the Rietzer See near Kloster Lehnin, the numbers are impressive since the beginning of counting and on April 13, 2012 more than 110 Black-necked Grebes were counted.

It was not until 2011 that the first Black-necked Grebes appeared at the Reckahner ponds, also in the municipality of Kloster Lehnin, but in a fish pond farm. Then there were no more reports for 7 years and then from 2018 onwards some reports, which then culminated in a Continue reading Distribution patterns of Black-necked Grebes

Dancing Great Egret in morning fog

Egrets in fog are a great motif. By the white color , the herons have always something mystical in the morning mist. White creatures are often used in myths and legends to serve as leaders to a different world. White deer, white horses and white rabbits are probably the most common associations for magic and are often brought into connection with fairies and other magical figures. To see a heron flying out of the fog in the first dim light of the early morning is a magical experience. The plumage of the Great Egret (Casmerodius albus) has a brilliant, pristine white. They seem to act as messengers from world far away from daily business life. The slow wing-beat has a unique beauty. If they stand patiently on the hunt in the shallow water, they are looking very majestic.

Great EgretIn nature only very few things are of pure white. Well, there are milk and snow , and of course white birds. A long time human being had to live with earthy tones, before technical progress brought us bleach and white color. White in the natural environment was unusual and therefore all the more fascinating .

There was no white heron in Germany when I was a kid. In general, there were very little egrets or herons. Herons were followed up in the 80s as a fish predator. The name “Fischreiher” (fishing heron) for the Grey Heron (Ardea cinerea) can be found even today in zoological textbooks. The Great Egret (Casmerodius albus) has spread only in the last few decades in Germany. The population is on the rise in Germany for about twenty years. First as a winter visitor the first nest could be detected in 2012 in the north of Germany. The first definite breeding record for the egret in Germany involved two couples who had settled in a colony of Grey Herons. Egrets are not part of traditional fauna of the country. The people , therefore sometimes mess up identification with storks and cranes . Of course, the Herons do not dance – just as those shown in the gallery – nor does the Spoonbill (Platalea leucorodia) dance on the images but they do follow each other. For fun or to secure their feeding territory? Who knows?

The Great Egret is the heron with the largest geographical distribution. It is found on all continents except Continue reading Dancing Great Egret in morning fog
