Polar bear mother with 3 cubs has lost 2 of them

In May 2015, a polar bear fami­ly with 3 cubs has been obser­ved in Tem­pel­fjord and Bill­efjord (click here for May arti­cle on this web­site).

Triplets are very rare, twins are nor­mal. The fema­le in ques­ti­on, did, howe­ver, not have triplets for the first time: in april 2011, she had alrea­dy been caught, seda­ted and exami­ned by sci­en­tists on the east coast of Spits­ber­gen, when she had triplets. Back then, only one of three cubs sur­vi­ved in the end.

In spring 2015, the fema­le was caught and seda­ted again. At that time, her 3 cubs were so small that they were not seda­ted, but they were pre­sent during the exami­na­ti­on of their mother. Accord­ing to data from the satel­li­te trans­mit­ter on the col­lar that was atta­ched to the fema­le on the occa­si­on, the fami­ly then star­ted a remar­kab­le jour­ney nor­thwards to spend the sum­mer north of Nord­aus­t­land. Later, they retur­ned south again, cros­sing Nord­aus­t­land, Hin­lo­pen Strait and nor­the­as­tern Spits­ber­gen to return to Tem­pel­fjord, whe­re the fema­le was recent­ly seen. Only one cub was still with her, the other two are appar­ent­ly lost. It is not known when and how they died, but it is com­mon that mother polar bears lose part of their off­spring during the first sum­mer or later. Access to food can be dif­fi­cult, and com­pe­ti­ti­on bet­ween the cubs can be strong then.
