Sažetak
During 1977-1995 the return of the local migratory breeding population of the starling (Sturnus vulgaris) from wintering quarters in North Africa to the area of Hrvatsko Zagorje was investigated. The earliest date of return was recorded in 1992 (February 7), and the latest in 1997 (March 4). During the 19-year research period, starlings usually returned from their wintering areas in mid- February. The first appearance at nesting-boxes was recorded 13 times during that period. The period of occupancy of all the 30 nesting-boxes regularly observed differs considerably from year to year. The later the date the starlings return from their wintering area, the shorter the period between the first observation and the occupancy of the nesting-boxes.
