KARL - 25.11.2016 (Nov. 25)/last data in autumn 2016/winter

EEDI - 19.11.2016 (Nov. 19) - 1.12. – 12.12. – 23. 12. (24.) – 30.12.- 12.1. - ...
Urmas wrote (2016): Data from Eedi during winter we receive after every 10 days through satellites, therefore long to wait for next ones.

probably we will have new data from Eedi on Dec. 7 - 8, but from Karl :puzzled: :bow:
we only can hope, that our storks are doing well :shake:

Thank you Solo for the pictures. :wave:
Only now I realize the immense vastness, which the birds are flying. On the map it does not look as far as on the globe.
You are doing wonderful work for us. :thumbs:

Last year Eedi had another transmitter, but now there is no any waiting days for data. Only what limits it is GSM coverage. Seems not always there in wintering area Eedi is accessible for data download.

Thank you, Solo 8-)

A stupid question which I never dared to ask: Black Storks are very secretive birds which need their peace and quiet and forest to breed.

Where they go for wintering is barren land, do they find enough shelter and food? Are there Black Storks who winter elsewhere, I mean not in a desert?

Rita :hi:

There are no stupid questions :laugh: We are curious, that's how we learn. This includes asking questions.

Here you can see the wintering areas from our Black Stork. The map is not up to date. There are also areas in Saudi Arabia. Eedi is there! The blue areas indicate, the winter areas from the European black storks.

They eat snakes, lizards and similar animals. But they also need water. They do not wintering in the desert.

Solo, thank you for the update :bow: :2thumbsup:

Solo :mrgreen: two answers are better than no answer! we have the same thoughts ..

Rita, it is very unusual/rare wintering area for black storks, but Eedi was successful in this area also previous year (2016, 2015 - with transmitter).
In Saudi Arabia, 200 to 300 storks are probably wintering in wadi's with permanent water in winter. (source http://www.aves.be/fileadmin/Aves/Bulle ... -4_127.pdf)

they are also trees, and storks spend the night also on rocks

Hello everyone! :wave:

Thank you Solo and Liz for all observations, comments and pics!
Rita, your question is very interesting.

Apparently, there is not very much information available about BS wintering in Africa.
This is what I found.

Study of fall migration of Black Storks (Ciconia nigra) by satellite telemetry, Aves, 40 (1-4) 2003 : 155 - 164
Most wintering grounds of Black Storks breeding in Europe are located in Sub-Saharan Africa. Most common natural habitats in wintering grounds are grassy, shrubby or tree-scattered savannah, enriched with water points, ponds or rivers (BOUSQUET, 1992). When human pressure is moderate, open habitats and low tree canopy favour the presence of Black Storks (D. Chevallier. Bird Study (2010) 57, 369–380).
When BS arrive on their wintering sites, the rainy season is just over and water levels in wadis and rivers are at their highest. With the progression of the dry season, those wadis dry up, leaving small separated pools behind where BS can easily catch fish (a very easy prey by then). The storks follow the drying of wadis, and finally come closer to the main rivers (HOURLAY, 1999).
(A wadi is a riverbed that is drying up during the dry season.)
Adults show a real fidelity to their wintering sites, as they do for their breeding sites. Immature BS (first and second years of their existence) have to search for sites that meet all the necessary features. Juveniles prospect widely for suitable habitats during their first winter periods.

(Chevallier D., Duponnois R., Baillon F., Brossault P., Grégoire J-M., Eva H., Le Maho Y. & Massemin S. 2010. The importance of roosts for Black Storks Ciconia nigra wintering in West Africa. Ardea 98: 91–96.)
Nocturnal roost of Black Storks is often situated in dead trees (46%) or poor-health trees (37%), and rarely in healthy trees.
Black Storks use on average 41 different nocturnal roosts during the wintering period.
Roosting trees were on average located at 3 km from foraging places.

URL: http://dx.doi.org/10.1080/00063651003678467
During wintering in Africa, Black Storks feed almost exclusively on fish (Chevallier et al. 2008) and follow the river courses. (Libois & Jadoul 1997, Jadoul 1998, Jadoul 1999) (However, during the breeding period in Europe BS consume a wider variety of food items including insects, fishes, small mammals, snakes, amphibians, lizards and passerine chicks.)
“Clearly, animals know more than we think, and think a great deal more than we know.”

Solo, Liz01 & Anne7: Thank you for explaining. Very interesting, also the part about roosting. This is the first season that I am following the BS migration thread. :blush:

:hi: Anne7,
TY very much for all yours source :thumbs:

The situation in Saudi Arabia, Bisha and Tarj Valley is another one - not the same how in Afrika (and Afrika is also not the same in all areas/very different where BS wintering). I think Eedis wintering area is very specific :puzzled: .

Btw. nocturnal roost of BS is not only in trees, it is situated also on power poles - e.g. Abu Na'ama (Sennar, Sudan) viewtopic.php?p=556541#p556541 and they are enough much photos storks roosting on rocks/mountains in Sharm el Sheikh area - for example: http://www.panoramio.com/photo/16661652 ... google.com
