White-rumped Sandpiper in Brandenburg at Gülper lake

WeißbürzelstrandläuferThe White-rumped Sandpiper (Calidris fuscicollis) – initially recorded as Baird’s Sandpiper (Calidris bairdii) – from Lake Gülper was intended to be observed on Saturday, July 22nd. Already at 7:00 am I arrived after 2 hours’ drive at the southeast corner of the small village Prietzen at the south end of Lake Gülper. Some birders had already placed their cars along the road. But on Saturday morning nobody had seen the bird in the Havelaue already.

Since Wednesday, July 19, the White-rumped Sandpiper had been seen loosely associated with river Little Ringed Plover (Charadrius dubius), Common Sandpiper (Actitis hypoleucos) and a Little Stint (Calidris minuta) on the sands on the banks of the southern shore. The White-rumped Sandpiper was busily searching for food with little resting phases. The bird was steadily to be seen until evening.

The southern shore of Lake Gülper is, however, crowded in summer by thousands of resting geese, predominantly Greylag Goose (Anser anser). For longer periods of time, White-rumped Sandpiper could not be found between the Greylag Geese. Thus, e.g. on Friday, July 21, 2017 between 7:45 and 8:00 pm, the bird could only be discovered after a White-tailed Eagle (Haliaeetus albicilla) had flushed all the Greylag Geese. Before that, he had not been seen Continue reading White-rumped Sandpiper in Brandenburg at Gülper lake

Weissbürzel-Strandläufer am Gülper See

WeißbürzelstrandläuferDer anfangs als Bairdstrandläufer (Calidris bairdii)  bestimmte Weißbürzelstrandläufer (Calidris fuscicollis) vom Gülper See sollte am Samstag, den 22. Juli beobachtet werden. Schon um 7:00 war ich die 2 Stunden angereist und stellte den Wagen am Südostausgang des kleinen Dörfchens Prietzen am Südende des Gülper Sees ab. Einige Birder waren schon unterwegs. Am Samstagmorgen  hatte aber noch niemand den Vogel in der Havelaue gesehen.

Der Weißbürzelstrandläufer war seit Mittwoch, 19. Juli, locker mit Flußregenpfeifern (Charadrius dubius), Flußuferläufern (Actitis hypoleucos)  und einem Zwergstrandläufer (Calidris minuta) vergesellschaftet auf den Sandflächen am Uferrand des dicht mit Mauserfedern bedeckten Südufers gesichtet worden. Der Weißbürzelstrandläufer war  hauptsächlich auf Nahrungssuche mit wenig Ruhephasen zu sehen und anfangs stetig bis abends anwesend.

Das Südufer des Gülper Sees wird allerdings im Sommer von Tausenden rastenden Gänsen, ganz überwiegend Graugänsen (Anser anser), bevölkert. Über längere Zeiträume konnte der Weißbürzelstrandläufer zwischen den Graugänsen nicht Continue reading Weissbürzel-Strandläufer am Gülper See

Remarks to wintering Solitary Sandpipers (Tringa solitaria) in the Pantanal

EinsiedelwasserläuferDuring scientific research in the northern Pantanal between the 20th of December 2012 and the 10th of January 2013 I often observe Solitary Sandpipers along the muddy ditches on a farm. Of the two subspecies of the solitary sandpiper recognized the subspecies present probably was Tringa solitaria solitaria which usually has a more well-defined streak between the eye and the bill which are clearly visible on the images shot. On the other hand Tringa solitaria cinnamomea typically lacks these streaks, being more finely spotted and speckled instead. First I saw the Solitary Sandpiper (Tringa solitaria) on the muddy fringes of small pools, where you could see them from wooden bridges crossing these waters. There were no more but 3 individuals which you could see at one time. In between 10 days the water level rose by about half a meter. After that you only saw Solitary Sandpipers on muddy pieces of grassland between leaves of grass. These patches were characterized by highly degraded grassland, where cattle used to feed on quite recently.

The Solitary Sandpipers were never numerous and obviously preferred the open muddy shores of various types of pools. In „Birds of Brazil, The Pantanal & Cerrado of Central Brazil“ von J. Gwynne, Continue reading Remarks to wintering Solitary Sandpipers (Tringa solitaria) in the Pantanal
