In total, 52 different pairs (about 61% of the estimated territorial pairs) had been characterised, 29 in the first year, 38 in the 2nd and 17 in the third (bad wheather). 23 pairs were recognised from the first recordings in the second year, 11 in the 3rd from the 2nd recording serie, 8 of them (= 27.9% of the 29 pairs found in year 1) were recognised in all 3 recordings.
10 and 5 pairs, resp., had different territories than in the preceeding year, equiv to 43.5 and 45.5% of the recognised pairs, resp. They were choosing new territories up to about 15 km away from the former year's location, although shorter distances are preferred.
4 pairs were divorced. In the majority of the cases, new mates are a female, and the new pair returns to the male’s property. We have one unusual case: here, out of two neighboured pairs, one male and one female paired and took over both territories.
