Description

The large Sotonera reservoir west of Huesca was put into service in 1963. During spring migration, thanks to its strategic position, it is used as a last stop for cranes before crossing the Pyrenees mountains between mid-February and mid-March.

Numbers accumulate when bad weather with strong winds and heavy rainfall prevent birds from crossing the mountains and up to 40,000 or even 80,000 birds have been counted on those occasions.

The most spectacular moments to observe cranes are in the morning when the weather is fine and large groups soar to cross the Pyrenees, disappearing behind the sierras near Riglos.

 

During winter (November – February) 1,000 to 2,000 cranes, wintering in the Sotonera, feed in the surrounding area.

In Montmesa the village just North of the reservoir, a small information centre has been set up (www.grullasmontmesa.es).

To get at the best places to watch cranes take the track that goes West from Montmesa.
After 300 m. you will cross a small bridge and the track divides into three.
On the left (item 1) you go to the Observatory (600 m, good for photographers), on the right (item 5) you go to La Mezquita where the largest numbers can be seen when they take off and straight ahead it will lead you to some old farm buildings named "Corral de Antonié". For the Corral de Antonié (item 3) turn left at the next junction and left again after 200 m. This spot gives you good views over an older reservoir called Alberca de Alboré, which is now part of the Sotonera reservoir and traditionally the most important resting place for cranes. When Alberca de Alboré is filled, groups of cranes gather on the island close to Montmesa.

Management

The site is protected as an Important Bird Area (IBA), the responsible organisation for this being the Aragón Government, but no management plan exists. Farmers are compensated with European subsidies for damage cranes may produce when feeding.

Since 1980 regular counts are carried out by the Huesca Bird Society called Grupo Ornitológico Oscense (GOO) and published on their website www.avesdehuesca.es.

The Limousin area is made up of three departments: Haute-Vienne (area capital for fire arts and porcelain), Creuse (Gueret) and Correze (Tulle).

 

 

 

 

 

 

Some geographical contrasts:

The area is made up of a layered landscape of plains, plateaux and mountains from west to east, with a basin in the south:
- some mountains in the east with a peak at 976 m: the Mont Bessou in Correze,
- some terraced plateaux from 300 up to 700 m high around the Limousin mountains,
- the Brive basin, a rich land and a door towards the South.

The Kingdom of trees and water:

Water is omnipresent in Limousin with:
- two large hydrographical basins: the basin of the Loire in the north and the basin of the Garonne in the south,
- three large artificial lakes: the lake of Val (north-east of Correze), the lake of Vassiviere (Haute- Vienne and Creuse) and the lake of St-Pardoux (Haute-Vienne),
- numerous lakes on which cranes sometimes stop for a while in order to take rest during the
migration (some immature cranes sometimes stay a bit longer, particularly in the spring).
The forest covers a third of the territory. The broad-leaved trees (beech, oak and chestnut trees) represent two thirds of the wooded surface whereas the evergreen trees are rather located in the mountain areas.

A mainly oceanic climate:

The climate changes according to the altitudes:
- on the Limousin mountain: a more continental climate,
- on the plateaux: a transition climate with a strong oceanic predominance,
- in the Brive basin: an Aquitaine type climate.

Agriculture :

The area is famous for its livestock farming (Limousin cows, sheep, ...).

The regional nature parks and the national nature reserves:

Thanks to a territory with natural, cultural and human resources, the Limousin has two regional nature parks:
- the regional nature park of Millevaches,
- the Perigord Limousin regional nature park on which the site of Flavignac is located (Long: 01°03'18''E - Lat: 45°43'53''N),
as well as two national nature reserves:
- Tourbiere des Dauges (Long: 01°25'17''E - Lat: 46°00'42''N),
- Etang des Landes (Long: 02°19'29''E - Lat: 46°10'49''N) located at Lussat in Creuse. The largest lake of the Limousin (100 ha) has some exceptional ornithological resources. Numerous cranes take a break there before starting again their migration.

The Common Crane:

This emblematic bird arouses many passions. The Limousin is entirely swept by the west migration corridor of the Common Crane, with a higher flight frequency over Haute-Vienne and Creuse. We can estimate that the majority of the cranes wintering in Spain and in the South of France (140,000 to 200,000 cranes) flies over our area.

Flavignac:

The site of Flavignac is located at the axis of the migration corridor at 25 km north-west of Limoges.
For around twenty years, numerous ornithologists have observed there many birds. One of the first ones has been Patrick Labidoire. For around ten years, the site is lead by an ornithologist of the village: Patrick Precigout.


The site is a real lookout tower for this corridor crossed by many birds, with two main bird-watching places at around 350 m high:
- for the postnuptial migration: near the hamlet of Cessaguet which is an open space towards the north-east and from which the city of Limoges can be seen,
- for the prenuptial migration: near the hamlet of Eynanças.
A continuous presence is carried out during the migration period, particularly by Patrick Precigout and Jean-Louis Vareille who operate an accurate counting of all the birds and particularly of the Common Cranes.
The site of Flavignac has henceforth joined the Reseau Mission Migration (www.migraction.net).

The Common Crane was a breeding species in Hungary up to the end of the 19th century, the start of the water regulation programmes carried out alongside the course of the large rivers and connecting marshlands. However, Hungary is one of the most important staging-over sites for the Common Crane in Europe as outlined in the followings.
Up to the end of the 1970-ies, Lake Kardoskút in South-Hungary was the most important roost site for cranes during spring and autumn migration periods.

From the beginning of the 1980-ies, its role was more and more taken by some artificial fishponds in the Hortobágy, which can be explained by the following reasons:

  • desiccation of the Lake Kardoskút because of a long droughty period
  • intensive hunting in the same spot
  • reduced hunting activities in the Hortobágy
  • fortunate, but unvoluntary synchronization of draining large fishponds (normal way of fishing) and peak time of migration.

Consequently, the peak number of staging cranes in the Hortobágy increased from 3,000 in 1983 to 65,000 to 1993 and then to 120,000 in 2015, which still continues to increase . Cranes roost in 3-15 roost sites annually depending on the amount of precipitation filling up marshes.  Roost sites are occupied by 2,000-70,000 cranes from mid-September to late November with peak numbers in late October.

However, it is important to note the increase of the number of non-breeding, oversummering cranes: this number has increased from 200 in the early 80-ies to 600 to the present time. In mild winters occasional overwintering also occurs.

Recognizing the importance of the Hortobágy in the survival of the Common Crane, the Hortobágy National Park Directorate started a programme aiding this process:

  • all sort of hunting is banned in and near roost sites
  • even public access is limited in such areas
  • it became an important consideration in marshland reconstruction programmes to provide suitable roost sites for cranes
  • maize is sown in arable lands inside the NP to attract cranes to less disturbed areas
  • showing the way of life of the Common Crane is an important feature in the study paths of the NP raising public awareness.

In the Hesse region, the migration of Common Cranes has been followed since 1987.
In Autumn and spring, 20 to 25 people count the migrating cranes every day. Martin Kraft sends the results of the counts to the migration specialists every evening through the list « grus-grus ».
These counts are very important for the survey of cranes in Europe and particularly in autumn for France as the birds which are seen in the Hesse region will normally then head towards the north-east of France (Lorraine and Champagne-Ardenne).

To get an optimal visibility, the counts are made from several places situated on higher elevations, between 300 and 400 metres above see level around Marbourg, on a 70- kilometre long line roughly centred on Marbourg, between Alsfeld (40 km east of Marbourg) and Herborn (30 km south-west of Marbourg).

The most important of these places are the roof of the Department of biology in the Marburg Lahn mountain (some 400 metres above see level), the Marburger Hasenkopf, west of Marbourg (340 metres) and the Altenberg in Odenhausen in the Lahn valley, about 17 km south of Marbourg (300 metres).

Der Chantecoq Lake : a regulator

Covering 4,800-hectares, lake Der-Chantecoq is the second largest artificial lake in western Europe. This reservoir was created to regulate the river Seine to avoid its devastating floodings in Paris and to support its flow in summer. The lake is fed by a canal that branches off the river Marne in Saint-Dizier and the outflow is a canal that joins the Marne in Arrigny.

Interest of the lake for birds

Situated on a major migration route between the northern breeding grounds and the wintering areas of France, Spain and Africa, it started attracting numerous species of birds as soon as it was created in 1974.
The filling up of the lake between December and June followed by its drain between July and November make the landscapes change drastically. When the water recedes, mudflats appear, attracting waders, ducks and geese, gulls but also the emblematic Common Crane thanks to which this site has acquired its international reputation.

The lake and the cranes

Lake Der-Chantecoq is very attractive for the Common Crane. It provides this bird :

  • a vast open space which is ideal for this wary bird
  • predator free islands where thousands of cranes can gather every evening and spend the night from October to March
  • pastures, meadows, oaks providing acorns, and fields (corn fields in particular) all around the lake
  • a vast undisturbed space, as the access to most of the lake is forbidden at this time of the year.

This lake is the main stopover and wintering site in Europe for this species. Every year, between 200,000 and 350,000 cranes stop there, either for a few hours or to overwinter. The last record dates back to 11th November 2014 when 206,000 Common Cranes where counted as they were leaving the lake early in the morning ! Some 20,000 to 30,000 cranes now regurlarly overwinter there.
This lake is a wintering site of major importance in Europe for many species of birds, therefore its preservation is essential.

History of the counts

A particular attention is paid to this species and numerous data have been collected :

The area is known as a resting area for at least 200 years. The positive development of the breeding populations in the countries of origin (Sweden, Norway, Poland, Baltic States, etc) has leaded to an increase of the numbers of resting areas and roosting places in the region, which covers today an area of over 1,000 km².

On the autumn migration from the beginning of September until the beginning of November up to 70,000 cranes with tens of thousands of geese (White-fronted, Bean, Greylag, Canada and Barnacle Geese) and ducks can take a rest there, in spring there can be for a short time up to 15,000 cranes.

Overall, over 20 sleeping places are known, seven of which are regularly used. The roosting places are almost all in the Western Pomerania Lagoon National Park and more precisely in two European bird reserves.

 

During the day, most birds feed on the land on the stubble fields around the Crane Information Centre (NABU, WWF, Lufthansa) located in the village of Groß Mohrdorf, 14 km northwest of Stralsund. In the permanent exhibition open all year round, you have the opportunity to learn almost everything about the cranes. Informative panels, audiovisual media and supplements give an insight into the life of this impressive big bird. You can discover the best observation places and get update information on the migration.

Special events, such as the "week of the crane" held each year in September and guided tours complete the range (Tel. +49 (0) 38323 80540, Fax - 80541, email: Cette adresse e-mail est protégée contre les robots spammeurs.

Very good viewing opportunities are possible on a platform at the feeding site of the Kranichschutz Deutschland (Organization Responsible for the Crane Protection in Germany) at the lake Günzer, 4 km SW from the Crane Centre.

There are special hides for photographers (info at the Crane Centre).

In addition to his informaton work to the public, the Crane Center carries out scientific research projects and coordinates protective measures at national and international levels. This includes, among others, the monitoring of ringed birds (colour rings) and the equipment in transmitters of some birds - in cooperation with some crane protection associations from other European countries, which enables the identification of behaviors during wintering and migration and the information on biological breeding.

drapeau franceLake Tåkern is one of the most important staging sites for Common Cranes, Geese and ducks in Sweden and an internationally important wetland for wetland birds. The nature reserve is a Natura 2000 area and is assigned under the Ramsar convention of wetlands.
The Reserve is 54 km2 and the lake is about 45 km2.

Huge reed areas of about 15 km2 surround the lakes edges. Tåkern is a very shallow lake with a mean depth of 0,8 meters only. The lake has a rich underwater vegetation dominated by myriophyllum and potamogeton.

The surroundings consists of grazed wet meadows and wet forests. A total of 270 bird species have been observed. The reed-living birds are specially dominant with 50 pairs of Bitterns and Marsh Harriers respectively and around 250 Great Reed Warblers. The breeding population of Cranes is increasing and is now about 25 pairs.

Furthermore, Tåkern is a key area also for waders, birds of prey (e.g. Osprey, Hobby and White-tailed eagle), and staging geese such as Bean Geese Anser fabalis fabailis, Greylag Geese Anser anser, Pink-footed Geese Anser brachyrhynchus and White-fronted Geese Anser albifrons.

A new popular Visitor Center was established in 2011 – naturum Tåkern.
