Our investigation was made in Cholgyni and Turov stations. Cholgyni
ringing station is located in Western Ukraine, 50 km west from Lviv, and Turov
station ? in Southern Belarus in Middle Pripyat.
Birds were mistnetted during autumn migration. Mist-nets were located
in reed beds and near willow bushes. Reed Buntings were tested shortly after
their capture with the Busse?s orientation cages for 10 or 15 minutes. A total
number of statistically significant tests were 212 (2000-2006) in Cholgyni and
46 in Turov (2005). For data processing following programs were used: Quatro
Pro 8 and Orient 4.5.
The results showed two directions of the Reed Bunting?s orientation: SE
and SW. In some years we observed also some minor directions, i.e. SW or
SWW in Cholgyni?s birds. When giving these directions in degrees, then it will
be SE - 126? (112-139?), WS ? 237? (226-251?), SW - 209-211? and WWS -
249-259? (to within 11?; on terms: 0? - North, 90? - East, 180? - South, 270? -
West). We have some retraps that confirm SW directions. And we assume that
the absence of retraps from SE direction can be bound up with element ringing
stations in east-southward.
Reed Buntings migrating through both ringing stations (Cholgyni and
Turov) show high repeatability of directional preferences in all studied periods.
