The Washington Wetland Centre near Sunderland is having a baby boom.
Now an overnight camera trap has caught (brief) footage of two young otter cubs swimming through a stream.
The centre has been keen to encourage wild otters to breed on site - and this shows they have been successful.
A six week otter pup found in a caravan park near Stockton is being rehomed this morning.
'Otty' was handed into a vet's surgery last week.
Since then he has gained weight and is now ready for a new life at a wildlife centre in Cheshire.
