Internet mapping for presenting satellite telemetry data from Lesser White-fronted Geese (Anser erythropus)
Within the project the method for searching and capturing goose (Lesser White-fronts) was worked out and successfully used on the large tectonic lakes with vast area, up to 100 m depth and coast line up to several hundreds of kilometers long. Really, the method for “searching of a needle in a hay stock” has been worked out. The team of only 4 people successfully used this method. In 2006 6 local breeding Lesser White-fronts were successfully captured and marked with satellite transmitters. Birds were marked since 24.07.2006 to 02.08.2006, during post-breeding moult. All marked birds were captured from the boat on the open water area of the lake. The signals of the transmitters, working over 100 days, have already revealed the main migratory direction of birds: from the Putorana Plateau birds fly south-westwards (over West Siberian depression to Kazakhstan). Argos-tools software was used on all stages for processing of the original telemetry data..

Schematic map of movement
General scheme of movements of marked Lesser White-fronted Geese, each color is for a certain bird. The detailed schemes of movements can be seen as the interactive maps based on Google Maps, and also as a more detailed map.
Short information on a state of marked birds on 01.04.07
At present the satellite telemetry is being received only from one bird - 3H (references are above; the other maps are not updated any more due to absence of movements).
After long staging at the border between Kazakhstan and Orenburg Province of Russia, the birds 3H and 0H flew over the Caspian Sea to the border between Iran and Nakhichevan Province of Azerbaijan, where they still stayed since early November not far from each other. 0H all the time was moving along the coasts of the large water reservoir in northern Iran (since 4.11 untill the end of December), 01.01.2007 it moved to southern Iraq to Mesopotamia. Last telemetry from this bird recieved on 13.01.07 from densely populated region of Kut-El-Amara city in Tigr valley. It is equally possible that it died or transmitter is out of order.
3H stayed for a long time on the junction of the border between Azerbaijan, Armenia, Turkey and Iran, at daytime in the Araks River valley, at night in the mountains of Iran. Between 30.11 and 03.12 the latter bird flew southward along the border between Syria and Iraq, where it stayed until the end of January (the Euphrates River valley). During this period, transmitters battery must have depleted, as the locations became rare and low quality. From 19.02 until 16.03 the bird stayed in Naryn-Chai river valey to the south of Mnt. Karatepe in eastern Iraq, ocasionally moving to nearby mountains. After 20.03 the bird started to move to nesting area. Location from Caspian Sea (to the south of Ogurchinsky island) could be a mistake, though it has a class 0, as the previous location A was obtained from the same wintering area 2.5 hours ago (this location was considered to be a mistaken one). Since March, 27 the bird is located in Kura river valey in Central Azerbajan.
Other birds:
Birds 4Z и 5B – the transmitters are likely damaged. Locations are absent since early September; however there was a location of A grade of the bird 4Z from the Pura and Taz rivers watershed on 9 October, but it is likely an error.
The bird 6B died between 19 and 23.08, but the transmitter works: The locations of high grades (1-3) are transmitted almost from the same point at Dyupkun Lake up till now.
The bird 7B also had most likely died, since the transmitter stopped working in the area with intensive hunting. However the transmitter damage is also possible.
