White-winged black terns in the Netherlands

This video is called White-winged Terns (Chlidonias leucopterus) in Belarus 2013.

The Dutch SOVON ornithologists report that this year quite some white-winged black terns have been seen in the Netherlands.

This species used to be considered a rare vagrant in western Europe. However, in 2007 over 1000 white-winged black terns passed the Netherlands on their spring migration to their nesting grounds, in Poland and still further to the east. And four couples stayed to nest in the Netherlands.

What will happen this year? It is still too early to say.

From the British Trust for Ornithology:

Summary of all Ringing Recoveries for Grey Heron (Ardea cinerea)

This page presents information on recoveries of Grey Heron that have been ringed or recovered in Britain & Ireland. The map shows all records of birds ringed in Britain & Ireland and recovered abroad (purple) and birds ringed abroad and recovered in Britain & Ireland (orange).

The table then summarises the number of birds that have moved between different counties of Britain & Ireland and between other countries and then gives a selection of recoveries. First are listed the number of birds found in each county, then the number of birds ringed in each county. In the next two columns are listed the number of birds ringed abroad and found in Britain & Ireland and the then number of birds ringed in Britain & Ireland and found abroad.

For longevity and distance records an individual is only included once, for reports to and from countries an individual may be reported multiple times, particulary if it bears a colour mark or other means of identification in the field. Some older (mostly foreign) recoveries are also included where these were received in the year reported on. For full details of how these birds have been selected click here.

For other information, have a look at the BirdFacts page for Grey Heron.

German cuckoo migration research

This video from Britain is called How to Tag a Cuckoo.

From Wildlife Extra:

German cuckoo satellite tagging programme – Where do German cuckoos go?

German cuckoos tracked for the first time

July 2013. The first Bavarian Cuckoo, fitted a few weeks ago with a mini satellite transmitter, has reached the Africa. Until now, it has remained a mystery as to exactly where the cuckoos head to, or by which route, when they leave Germany after their brief three months stay. Thanks to the international project can now for the first time both the conservationists and the general public watch live on the internet, draw routes on which the popular birds with their high-tech backpacks in the south and where they reside there until the next spring.

A cuckoo known as “Richard” was tracked to eastern Libya, an area mainly dominated by desert. From his capture in Bavaria his route led him initially to Switzerland, then down through the Italian boot and finally over the Mediterranean. Among the 13 cuckoos given satellite tags in Germany, two animals were in Italy and four in the Balkans.

Several cuckoos, as part of the same project, were tagged in Belarus, with some interesting results. They appear to be heading for the same part of Africa, by very different routes, including one that flew south via the Arabian Peninsula, Eritrea and Sudan.

Why they spend time there, when soon the birds will move on on completely different routes to Africa, only to meet again in Africa, are the interesting questions to which the international telemetry project aims to find answers in the coming days, weeks and months.

You can follow the German & Belarussian cuckoos here.

“Already at the beginning of the migration period, we have discovered how little we know,” said LBV Conservation Officer Andrew of Lindeiner. “It starts with the unpredictable migration routes and continues with the different rest areas and regions that are flown across without stopping.”

Successfully conserving the Aquatic Warbler

OTOP (BirdLife in Poland), Aquatic Warbler singing

The numbers of Aquatic Warblers are declining in Europe mainly due to habitat loss and speeded up by changes in water management. The Polish Society for the Birds Protection (OTOP, Birdlife Partner) started a project to protect Aquatic Warbler back in the 1990s and conservation measures have focused on two big projects financed by the LIFE Programme.

In 2012, OTOP conducted a national Aquatic Warbler count, in which birds were counted not only in the places where conservation measures, like mowing and bush removal are taking place, but also at smaller sites throughout Poland. During these counts, thanks to an enormous effort of over 120 volunteers, OTOP now estimates the population at 3,256 male birds. This result supersedes the count in both 2007 and 2009; so it seems the decline has stopped.

Compared to other countries it appears like the Polish population of Aquatic Warblers is the only one that is stable. In Belarus and Lithuania the population decreased in 2012. Fortunately, conservation measures of restoration or increasing the quality of habitats are being implemented also there. In Germany, after several years of absence, three singing males have been observed in the Lower Odra Valley. Due to lack of research the situation of the species in the Ukraine and Russia is not known at the moment.
