In the field season of 2007 we mounted an adult male crane “Matti” with a 80 g battery powered PTT manufactured by North Star. The crane was captured in Eastern-Lapland, Finland, where it stayed within its home range with a female crane from early May to late August. The pair did not produce any offspring, which was in agreement with the field observations from much of Northern Finland where the chick production of crane appeared to be low in the summer of 2007.
