Black Terns catching flies in the Danube Delta

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 have been categorized as: gleaning (perched bird takes prey from branch or tree trunk), snatching (flying bird takes prey from ground or branch), hawking (bird leaves perch and takes prey from air), pouncing (bird drops to ground and takes prey) and pursuing (flying bird takes insects from air).
To cope with the growing demand for top shots of the rarer species of the Palearctic Bird-Lens is keen to enrich the range of pictures of birds you can find in the western palearctic. Trips to remote places as described above – but also to the in Macin Mountains – to capture images of rare birds of western palearctic were very successful. The nice images you find in the gallery are only a first impression, what you will find in the gallery in the “Pictures Shop” very soon. Just give me a message, if I could serve you with an image needed before the new pictures are online.
Other successful shootings you can see in the Picture Shop under: www.bird-lens.com.
