Sažetak
I made an experiment with egg removal on the nest box population of the Starling in the Mokrice (NW Croatia). The manipulation was done on a total of 12 nest (first clutch, April 2003). Each morning I checked nest-boxes to determine the timing of clutch initiation. In two nests I removed all eggs laid after the first laid egg, in two nests after the second, in two nests after the third, in two nests after the fourth and in two nests after the fifth laid egg. In two nests I removed the first laid egg and every egg laid after the first one. Eggs were removed from the nests on the days they were laid. The average removal clutch size (i.e. total number of eggs laid in rasponse to egg removal) of these ten nests was 6.11 eggs. It is not a significant difference (p>0.05) in relation to the average clutch size in Starling in this area.
