Abstract:
In the 1950’s, the Lesser White-fronted Goose (Anser erythropus) was a regular migrant in Western Finland during spring migration, but in the 1960’s the number of migrants seen has decreased abruptly despite increased ornithological field activity. This maybe an alarming indication of a very recent decline in the Scandinavian breeding population of the species.
