What elements affect the Lesser Spotted Woodpecker migration?
Last Friday a study was published in the peer-reviewed journal Ornis Norvegica. The article presents the results from a study of 136 Lesser Spotted Woodpeckers ringed at Lista Bird Observatory during the last 26 years.
Although little is known about the migration of this species along the coast of southern Norway, this study shows that sex, age and physical condition may affect the birds of this species and when they actually migrate.
It is also shown that the numbers from Lista are positively correlated with the corresponding data from Falsterbo Bird Observatory (in southern Sweden). This suggests that the annual variation in the number of migrant birds are quite similar over a wide area in Scandinavia.
