News of the birds tagged with GPS / GPRS transmitters from the Rescue Centre.

04.12.2012
As we reported earlier, unfortunately “Theo” the Long-Legged Buzzard was found dead in August near Varna. The analysis of the coordinates of the GPS / GPRS transmitter confirms our conjecture that the death of Theo found by railroad Targovishte – Bulgaria was either hit by a passing train, or died by the voltage of the wires, but in both cases the scene does not match the location of the find. It happened between 12:44 pm on August 28 to 06.44. August 29.

The Lesser Spotted Eagle “Crea”, who was freed in early September near a protected area is still there. Recent data on Crea stopped in the middle of last month, when unfortunately the battery voltage of the transmitter fell, and he went into protection mode. The reason is that Crea spent most of their time perched and partially covered. The solar panel was also covered by the feathers of the bird and did not allow the transmitter to charge normally. Although we conducted field monitoring at the end of last month we reached a visual contact with the Lesser Spotted Eagle. So Crea is yet to start the migration, albeit much later than other Lesser Spotted Eagles. We expect when the transmitter is loaded, we will continue to receive location data from her.

Hollyhock, a White Pelican who was freed a month and a half ago, lived in Vaya Lake and Mandra near Burgas until the signal ended. Unfortunately for about a month now we have had no data from the transmitter, and we cannot confirm with certainty the fate of the young pelican.

There are also interesting developments around the two owls released last month.
Owl “Bagan” who was released immediately after tagging it with the transmitter turned south and crossed the Balkan Mountains near Shipka and then became established in the lake area of Koprinka. The most recent data from its transmitter was 11th Nov. Field monitoring conducted at the end of the month did not lead to eye contact with the bird. But the place is very rich in food, and is inhabited by many raptors such as buzzards, harriers, falcons and Dr. Tova still gives us hope that the owl was able to eat and adapt successfully. The Owl may have been moved to an area where there is no coverage from the mobile operator, and therefore cannot get information. So we continue to hope that soon we will see what happens to Bagan.

Another Owl “Bulgarka” was released a week after marking it with a transmitter from the aviary in GMP Bulgarka. Unlike Bagan, he turned to Gabrovo, following the river, and was found in an industrial area in the north of the city. Just as we prepared to check the spot for how and why it stayed there the transmitter data showed that the bird had a problem. A visit to the last coordinates of the owl confirmed our concerns ... and Bulgarka was found dead on the roof of a building. An autopsy showed that the probable cause of death was septic process (or starved in consequence occurs multiplication of pathogenic microorganisms or root cause is a disease in consequence of which he died).

Another of our patients a Lesser Spotted Eagle called Boril who was liberated in the Eastern Rhodope at the end of July, beginning a long stay near Municipality. After monitoring of the site by a team from Green Balkans, it was identified in migration with a small cluster of dozens of eagles.
So on Sept. 13, nearly a month and a half after his release, began the autumn migration of the young Lesser Spotted Eagle which took him to Cairo.

It was a struggle at first in its long journey, across the Bosphorus, then the central part of Turkey, around the Mediterranean Sea to the east, and is currently located in the Nile Delta in Egypt, Africa. For nearly 30 days the migrating Eagle travelled over 2393 kilometres. On the way, it struggled and stayed for several days in the regions of Turkey and the Suez Canal. In November Boril went up the Nile. For several days we have had no information from him, and we think he has focused in areas where no mobile operator connection.

We hope to see that our assumptions are correct.

And if the information about our birds seems rather pessimistic, then we only regret that we can try to prepare them as best we can and give them a new chance at life in the wild ... but life in the wild is cruel, and is subject to other, often major forces.
The use of advanced tracking technologies, however, gives us new information that otherwise we cannot get. Everything you learn about our patients and their level of adaptation in nature will help us to optimize their work and be more effective in protecting the biodiversity of our country.
