CAMERA TRAPS
In April we installed digital camera traps at a location on Skye where we have
been monitoring the otters, so that we can see how often they use freshwater
pools. The cameras detect movement
and can provide either still images or video as well as date and time.
Every time we check the cameras there is great excitement to see what has been
photographed. Sometimes we come
back to the computer with over 100 photos but to our disappointment a very large
percentage turn out to be sheep! We
also have excellent shots of oystercatchers, hooded crows and heron.
But then there are the actual otter pictures:
shadowy night shots of an otter grooming and rolling on its back;
a single animal running across the grass and the most exciting – a female
with her two cubs!
They have now been in place for six months and have already provided some
interesting insight into otter behaviour.
Unlike otters in freshwater which are largely nocturnal, we had always
believed our coastal otters were diurnal.
So we were surprised to find photos of the otters taken at their
freshwater pool at night on several dates in May.
Activity at night would be understandable in winter as day length is so
short but in June we have a photo of two otters taken at 1.30am and by then it
barely gets dark. So it would
appear that these otters are active on and off throughout the day and
night.
Here are just a few of the photos:
