Seasonal changes in diel haul‐out patterns of a lacustrine ringed seal ( Pusa hispida saimensis)
Abstract Seasonal changes in diel haul‐out patterns of the lacustrine Saimaa ringed seal ( Pusa hispida saimensis ) were studied using a combination of satellite telemetry and camera traps during 2007–2015. We found the haul‐out activity patterns to vary seasonally. Our results show that during the...

In contrast, over the spring molting period, Saimaa ringed seals tend to haul out around the clock. The spring molt is also the only period when a slight difference in haul‐out behavior between the sexes is observed, with females having a haul‐out peak at nighttime while the males have a less visible diel pattern. According to our results, the diel haul‐out patterns of Saimaa ringed seals are similar to the ones of marine ringed seals.
