- Tiaiset, leppälinnut ja pikkuvarpuset pesivät avoimissa pystyputkissa. "The preferred diameter of pipes increased with the size of the bird species as measured by the tarsus length -- This is related to the mechanism of bird locomotion up and down inside the pipes. In too broad or too narrow pipes birds are limited in climbing on a tube surface. Moreover, narrow pipes may decrease the breeding success by reducing the space for young, as it was pointed out for the Great Tit in the study area."
