Nachdem ich die Steppenweihe (Circus macrourus), einen wundervoll, elegant fliegenden Greifvogel schon bei Reisen im Monat September auf ihrer Zugroute entlang der Schwarzmeerküste in der Nähe südlich des Donau-Delta und an der Schwarzmeerküste in Rumänien sowie an der Wolga in Russland gesehen hatte, war ich gespannt, ob es mir gelingen würde, diese Vogelart auch während ihres Aufenthalts im Winterquartier in Äthiopien zu sehen. Vorher hatte ich Steppenweihen in Afrika bereits in ihren Winterquartieren in Südafrika (Krügerpark) und Continue reading Awash NP: Weihen im Winterquartier in Äthiopien
Spectacular numbers of Pallid Harrier, Circus macrourus, and Red-footed Falcon, Falco vespertinus, were the highlight of the first day. Having spent 3 days in May north of Constanta at Romania´s Black Sea coast, it was decided to try our luck with birds again in the area around the village of Vadu. The target was, to increase the birdlist and to look what differences in the bird diversity we could experience. South of the Danube Delta is wide stretch of a sandy shoreline with shallow lagoons. This is part of Romania´s Black Sea coast. September– like May – is migration time. Whereas the association of the east Romanian countryside is normally with the core Danube Delta with its special birds like Pelicans, Black-necked and Red-necked Grebes, Glossy Ibises, Spoonbills, the stretch of coast just south of the Danube Delta up to the northern city limits of Constanta is an excellent birding spot not only for migrating birds, too. Two dedicated bird photographers went for the countryside area near of Vadu at the sandy coast in the 3rd week of September 2012. The area called Dobrudja with its steppe habitat more to the west was neglected this time. All breeding specialities should have gone already.
The trip date was perfect, allowing us to see good variety of species, many of them in considerable numbers, especially raptors. We also saw waders, gulls, herons, pelicans and passerines.
The Bird Diversity we enjoyed was high; exactly 90 species of birds we found in only 2,5 days. Highlights of the tour you will find in the gallery. Among others we made photos of Black-necked Grebe, Podiceps nigricollis, Dalmatian Pelican, Pelecanus crispus, Purple Heron, Ardea purpurea, Ruddy Shelduck, Tadorna ferruginea, Common Shelduck, Tadorna tadorna, Black Kite, Milvus migrans, Western Marsh-Harrier, Circus aeruginosus, Pallid Harrier, Circus macrourus, Montagu’s Harrier, Circus pygargus, Eurasian Sparrowhawk, Accipiter nisus, Red-footed Falcon, Falco vespertinus, Eurasian Hobby, Falco subbuteo, Peregrine Falcon, Falco peregrinus, Common Quail, Coturnix coturnix, Syrian Woodpecker, Dendrocopos syriacus, Red-backed Shrike, Lanius collurio, Sedge Warbler, Acrocephalus schoenobaenus, many Willow Warblers, Phylloscopus trochilus, Common Chiffchaff, Phylloscopus collybita, lots of Blackcaps, Sylvia atricapilla, only a few Common Whitethroats, Sylvia communis, many Lesser Whitethroats, Sylvia curruca, many Spotted Flycatchers, Muscicapa striata and Red-breasted Flycatchers, Ficedula parva, good numbers of Common Redstarts, Phoenicurus phoenicurus, Whinchats, Saxicola rubetra, Northern Wheatears, Oenanthe oenanthe and a single Tawny Pipit, Anthus campestris.
This tour gave us the opportunity to witness the spectacular autumn migration Continue reading Fall migration at the Black Sea Coast/ Romania
Looking at field guides like „ Collins Bird Guide“ from Peter Grant, Dan Zetterstrom, Lars Svenson and Killian Mullarney the ID look quite simple. But even in the breeding plumage Chlidonias – or Marsh – Terns can cause some headache identifying in the field. Then even the Whiskered Tern (Chlidonias hybridus) can be confused with the Black Tern (Chlidonias niger) especially if seen in poor light facing the sun when both terns look remarkably dark.
A remarkable fact is, that the scientific name arises from Whiskered Tern´s similarities in appearance to the Black Tern but also to the (more whitish) Sterna – Terns.
To distinguish Black Tern (Chlidonias niger) and the 3rd member of the genus, the White-winged Tern (Chlidonias leucopterus) is even more sophisticated. The wings do not always look decidedly white – as the name suggests. Often the upper parts of the wings do not look so much brighter than in the Black Tern. On the other hand a good deal of black is shown in the underwing-coverts. Hence the black & white contrast of the underwings might be the best criterion to distinguish flying White-winged Tern from Black Tern in the field.
In flight, all these terns appear slim – less so the Whiskered Tern. The wing-beats are full and dynamic, and flight is often erratic as they descend to the surface for food. Chlidonias – or Marsh – Terns do not dive for fish, but forage on the wing picking up items at or near the water’s surface or catching insects in flight. They mainly eat insects and fish as well as amphibians. The feeding habit is quite unlike Continue reading Identifcation of flying Chlidonias Terns in breeding plumage
I was almost titeling Black Tern flycatching… but then I found an interesting nice article in Wikipedia, (http://en.wikipedia.org/wiki/Hawking_(birds)) to the meaning of feeding strategies of birds involving catching flying insects in the air. Wikipedia says, that the term “flycatching” refers to a technique of sallying out from a perch to snatch an insect and then returning to the same or a different perch.” Ok, this is not what I saw in mid May 2012 in the Danube Delta. For sure, a flock of approx. 50 Black Terns (Chlidonias niger) in a joined effort with some Whiskered Tern (Chlidonias hybridus) were catching flies in a swift, elegant and almost effortless looking manner but now I know, you should not call it “flycatching”.
2 species of Chlidonias – Terns, Black Terns and Whiskered Tern are breeding in the Danube Delta. Mid of May they have just arrived from their wintering grounds and they are in urgent need of nutrient-rich food after the strenuous migration and in preparation of breeding. A mass occurrence of black flies is the right food to fill up resources for the tasks ahead. The gallery show more pictures of the terns in the air that one unforgettable evening mid of May in the Danube Delta/ Romania.
According to a very nice article in Wikipedia. The various methods of taking insects Continue reading Black Terns catching flies in the Danube Delta
South of the Danube Delta is a wide stretch of a sandy shoreline with shallow lagoons. This is part of Romania´s Black Sea coast. May is Migration and early breeding time. Whereas the association of the east Romanian countryside is normally with the core Danube Delta with its speciality birds like Pelicans, Black-necked and Red-necked Grebes, Glossy Ibises, Spoonbills, the stretch of coast just south of the Danube Delta up to the northern city limits of Constanta is an excellent birding spot, too. A small group of bird photographers went for that countryside, with the area called Dobrudja more to the west and the area of Vadu at the coast. The tour was organized by Sakertours. The Bird Diversity we enjoyed was high; over 90 species of birds we found in only 3 days, some had just arrived from their wintering grounds in Africa. Highlights of the tour you will find in the gallery. Among others we made photoshots of Great Bittern, Botaurus stellaris, European Honey-buzzard, Pernis apivorus, Montagu’s Harrier, Circus pygargus, Long-legged Buzzard, Buteo rufinus, Lesser Spotted Eagle, Aquila pomarina, Imperial Eagle, Aquila heliaca, 2 species of Sparrowhawks Continue reading Top Birds at Romania´s Black Sea Coast
Bird Diversity in the delta of 2ndlargest river delta in Europe, after the Volga Delta is very high. Over 320 species of birds are found in the delta during the summer, of which 166 are breeding species. A group of bird-photographers decided to visit this site in May 2012 on a trip with Sakertours. Highlights of the tour you will find in the gallery. Among others there were photoshots of 7 species of herons (Little Egret, Egretta garzetta, Grey Heron, Ardea cinerea, Purple Heron, Ardea purpurea, Great Egret, Casmerodius albus, Squacco Heron, Ardeola ralloides, Black-crowned Night-Heron, Nycticorax nycticorax, Little Bittern, Ixobrychus minutus), 2 species of pelican (Great White Pelican, Pelecanus onocrotalus and Dalmatian pelican, Pelecanus crispus), 3 species of grebes (Red-necked Grebe, Podiceps grisegena, Great Crested Grebe, Podiceps cristatus, Black-necked Grebe, Podiceps nigricollis), 2 species of Chlidonias-terns (Whiskered Tern, Chlidonias hybridus and Black Tern,) Chlidonias niger), 2 species of ibises (Glossy Ibis, Plegadis falcinellus and Eurasian Spoonbill, Platalea leucorodia) and top birds like Pygmy Cormorant, Phalacrocorax pygmeus, White-tailed Eagle, Haliaeetus albicilla among others
Starting from Mila 23, a village right in the middle of the Romanian part of the delta Continue reading Bird Diversity in the Danube Delta
The Danube Delta is home of two species of pelicans. The pelican is the symbol of the Delta. Here is home to Europe’s most important colony: 3.500 pairs live in the Danube Delta . we decided to visit this site in May 2012 on a photographer trip with Sakertours. One of the highlights were photoshots of starting Great White Pelican, Pelecanus onocrotalus and Dalmatian pelican, Pelecanus crispus.
With his 9 – 11 kg of weight the adult Great White Pelican is one of the heaviest and largest flying birds in the world. Ahead of this pelican species in weight is only the Dalmatian pelican (Pelecanus crispus), Black Vulture (Aegypius monachus), the Great Bustard (Otis tarda) and the Mute Swan (Cygnus olor). To provide his lungs with enough oxygen, he has five air sacs, which extend through the entire abdominal cavity. A special technique is also the flapping flight, with which he strikes 70 times per minute, a gull (Laridae), e.g. needs 180 beats per minute. With its 3.60 m wide wings the Pelican is able to use (as one of only a few water birds) the thermals by the rising warm air for circling in the air without any physical effort of his own.
Like many birds, the pelican has a very light skeleton. His bones Continue reading Great White Pelican takes flight in Danube Delta
