This past weekend, Sea Watch
Foundation held its annual training course, where members of the public could
attend lectures and gain fieldwork experience in cetacean research. Lectures
covered topics such as the marine mammals found in UK waters, how data is
collected, and the importance of the Sea Watch sightings network for
understanding the distribution, behaviour and habitat use of cetaceans as well as
implementing and maintaining Special Areas of Conservation.
Trainees joined us first thing on Saturday
morning, ready for the weekend ahead. After initial introductions, the trainees
were launched into the amazing world of marine mammals, learning how to
identify them from their fin type, body size and other features. Survey methods
that Sea Watch uses were also covered, as well as the use of underwater
acoustic monitoring.
Land watches from Birds' Rock and boat trips
in Cardigan Bay were also conducted on both Saturday and Sunday so that the
trainees could put into practice the techniques that were learnt during the
lectures. Observers took turns filling out the effort and sightings recording forms,
which provide valuable data.
The weather had been pretty dire over the weekend,
but we were fortunate to still see dolphins on the land watches as well as the
boat surveys, despite the poor sea state.
There was a mix of apprehension due to the
weather conditions and excitement at the prospect of what we might see on the
second boat trip of the weekend. The trainees and Sea Watch volunteers and staff
boarded our survey vessel and prepared the equipment and observers for our search.
Upon leaving New Quay harbour the conditions were really not favourable; the
swell reached over one metre and the sea state left much to be desired.
However, approximately fifteen minutes into
the survey the observers spotted a group of seven bottlenose dolphins, one of
which was a newborn calf. Thirty metres off the bow a commotion ensued and a
small body was seen being flung into the air amongst some of the adult
dolphins. Initially it was thought to be a porpoise that was being attacked,
but after multiple observations it was confirmed to be the newborn calf. Looking
back through photos of the incident and comparing them to individuals in our photo
ID catalogue, Sea Watch staff concluded that the dolphin responsible for the
calf’s aerial activity was quite possibly its own mother.
The reasoning for this behaviour is not
clear, but Peter Evans, Sea Watch director, suspected it was a form of scolding,
perhaps to ensure the infant did not come too close to either a hostile male
dolphin or to the survey vessel. Another possible explanation is that the
behaviour was just playful. The calf luckily was seen swimming very closely
alongside its mother from that point onwards, suggesting that the calf was not
injured badly. The spectacular event was also witnessed by a volunteer and guest
conducting a landwatch from the cliff tops of New Quay and from the harbour
wall. It was an occurrence rarely seen
and one that will certainly be remembered by all of the trainees and Sea Watch staff.

Overall, the training weekend was a busy,
information-packed experience, but was thoroughly enjoyed by all those who
attended.
