The
Seychelles magpie robin (Copsychus
sechellarum) at one stage was facing extinction. With numbers as low as
twelve, it looked like this species would be consigned to the ages as another
extinction brought about by habitat destruction the accidental introduction of
rats (stowaways on shipping vessels). Fortunately this has not been the case at
all and they have been a truly remarkable success story of conservation proving
that it is not too late to take positive action and save a species.

Denis
Island has the privilege of being a part of their recovery. The magpies are
believed to have inhabited most of the Granitic islands of the Seychelles
however with the development of these islands and the introduction of rats by
accident and cats (to control the rats), they quickly went extinct on all but
one island (Fregate island). As part of the recovery efforts, the magpies were
translocated to other islands that provided the right habitat for the and
crucially, were rat and cat free. Translocation efforts not only increase the
overall area the birds can be found in thus allowing a larger population of
this highly territorial species, they provide security that should a population
fail due to disease, habitat destruction or introduced threats, populations of wild
birds still exist.
Denis
Island was one such destination and, in 2008, 20 magpie robins were translocated
here. Since then, the birds have been monitored by conservation staff on the
island to ensure the population is stable/ growing and the birds are showing no
signs of disease or abnormal behaviour. It is was observed that the invasive myna bird on Denis was having a detrimental effect on nesting success as this
problematic species is a nest raider eating both eggs and chicks. This species
was eradicated in 2015 and it is with great pleasure to say that since the
initial 20 birds first released, the 2016 census showed magpie numbers on Denis
were up to 78!

Success
stories like this are only possible thanks to constant monitoring of
populations of wildlife especially species at risk and then the appropriate
steps taken to ensure success. Even after the huge challenges of moving a
species, constant monitoring still needs to be done to look for any potential
problems on the horizon which can be prevented before having a chance to take
hold.
By visiting
Denis or the other islands with magpie populations, you are helping contribute
to the protection of such a fascinating species and we hope you are fortunate
to see these charismatic birds whilst you are here.

Fun fact:
The Creole name for this species is pisantez means ‘singing pie’. Pie after the
birds black and white plumage, and singing because of its melodic voice.
