Anhingas in Florida

Amerikanischer SchlangenhalsvogelThe ditch along the visitor’s trail is teeming with fish. Suddenly a sharp, dart-like beak emerges out of the water right in front of us. It is followed by a long piece of neck. Like a snake, Anhingas – the snakebird – (Anhinga anhinga) glides silently through the water. Its water-permeable plumage reduces the buoyancy that occurs during diving and suppresses any rippling. For a while we see the slender bird body still sliding underneath us through the fairly clear water. Now it’s time to take care. Far more spectacular than Cormorants (Phalacrocorax carbo) they fish under water. Anhingas use their pointed beak like a harpoon. The long neck, which is bent back in an S-shape before being impacted works like a taut feather and allows lightning-fast fishing under water. The Anhinga Trail in Florida’s Everglades offers ideal conditions to observe these black fish hunters. They harpoon the fish by piercing it with their closed beak.

Pochard: a bird population in decline

TafelenteThe fate of the Common Pochard is discussed intensively in the relevant forums. Scientific research suggests that the sex ratio of the populations of Common Pochard (Aythya ferina), a medium-sized diving duck, in Europe and North Africa has changed. This could play a role in the decline of the species in the Western Palearctic.

Sex ratio results have just been published in the Wildfowl & Wetlands Trust (WWT) Journal Wildfowl. These conclusions show that populations are becoming increasingly “masculine”. Using the data obtained in January 2016, the researchers compared counts from surveys conducted in January 1989 and January 1990 in the same region. The proportion of men in the total population was 62% in the years 1989 to 1990 and in 2016 this disparity even increased to 71%.

Interesting clues for the pochard, a bird in a sharp population descent, provides an investigation of ZIMMERMANN, H. (2010), which was published in: Brut und Mauser der Tafelente Aythya ferina im Naturschutzgebiet Fischteiche in der Lewitz (Breeding and moulting of the pochard Aythya ferina in the nature reserve fish ponds in the Lewitz) in Orn. Newsletter Meckl.-Vorp. 46: 367-373.

The fish ponds in the Lewitz are a traditional breeding and moulting area of the Common Pochard in Mecklenburg-Vorpommern in Continue reading Pochard: a bird population in decline

Handa, a Scottish bird island

SkuaSpray foam feet high. The air is impregnated to the saturation limit in puccinellia. Metre-high waves crash against the craggy, rocky shores that extend indomitable and majestic into the air. Just having left the small fishing port of Tarbet in County Lairg, Highland in a calm sea, a beautiful sound between a rocky coast and a rocky island enchants the visitor. The crossing to the bird island is short-lived. The landing site is an unaffected looking, lonely sandy beach. But this is the east side facing away from the Atlantic sea. On the west side, the world looks very different. Sun rays breaking through the cloud cover giving the wild scenery wrapped in warm colors a melancholy charm. The air is filled with the piercing cries of a countless multitude of seabirds. Despite cold, wind and water they have set their breeding colony on Scotland’s west coast.

The visitor is first simply overwhelmed when the first rays of the wild scenery of moss and rocks give off warm colors wrapped in melancholy charm. In the distance the Continue reading Handa, a Scottish bird island
