Summarised
results of wintering inventory of Red-breasted Goose in Ukraine in 2003-2006
In general, seven field teams coordinated by leading Ukrainian
ornithologists participated in the winter inventory of red-breasted Goose in Ukraine
during three years. Inventory areas for each team were as follows:
- Danube region and delta, Odessa region — M. Zhmud;
- Black Sea coastal zone from Odessa city to Lake Sasyck, Odessa region — I.
Rusev;
- Black Sea coastal zone and estuaries in Mykolayiv region — Z. Petrovich;
- Black Sea coastal zone in Kherson region — O. Yaremchenko;
- Continental area in Kherson region and coastal zone of the Carkinit bay —
V. Havrylenko;
- Coastal area in Zaporizhya region, Eastern Syvash — V. Popenko;
- Western and Central Syvash, Steppe Crimea — O. Hrinchenko.
Teams used both point and route methods of counts. They counted
geese at the key sites where birds fly off in the morning and then continued work
at the most important sites of region. Combination of methods allowed to cover
previously identified main roosting sites and other irregular groups with considerable
number. Unlike methodological approaches applied in Romania and Bulgaria, Ukrainian
ornithologists didn’t use point method as a basic, because geese in the Azov and
Black Sea region are very dynamic in utilizing feeding sites and roosting waters.
Apart from the Red-breasted Goose, teams also counted other species that occurred
along the routes, namely, the White-fronted Goose Anser albifrons, the Greylag
Goose Anser anser and the Lesser White-fronted goose Anser erythropus.
Results of the winter inventory indicate instable character of
the wintering groups of the Red-breasted Goose in the Azov and Black Sea region
of Ukraine. Main factors of instability are as follows:
- Unusual weather conditions;
- Poor feeding resources on the field with winter cereal crops;
- Disturbance of the population by hunters and poachers during hunting season;
and
- Disturbance of the birds by poachers during other seasons
Considering the summarised data for 2003-2006 the highest number
of the Red-breasted Goose is registered in Ukraine in January.

Project results have an important scientific value mostly for
understanding the mechanism of establishment of wintering groups of birds, analysis
of weather impact upon distribution of wintering birds in the region, and terms
of stay and time of geese departure from the Azov and Black Sea region. Project
plays significant role since results of inventory in 2003-2006 can be used for
revision of an Action Plan on the Conservation of the Red-breasted Goose in Ukraine
and in the whole species habitat as well.
