If you was a birds doing serious mileage each year, coming
up from a place where food is plentiful and passing up through Africa and
Europe and ending up in Shetland around mid- May only to find that a few more
of your neighbors have failed to make the journey this year, would you be in a
good frame of mind?
Then after settling down with your mate you managed to
produce some eggs, closely guarding them from all intruders such as Skuas,
gulls, rats and even otters. They hatch out and the race is on to find enough
food which is hard to find most years.
These are Arctic terns who for around 20 years or so have
found going difficult, numbers in Shetland being reduce from around 35,000 to
around 7,000. Having traveled around 22,000 air miles a year for 15- 20 years
they have not produced any young for a number of years.
This year however things are looking a lot better, perhaps
the best year for 20 years, with a large number of adults bringing in large –
medium sand eels for several weeks.
As a result some Juv Arctic Terns have been seen at three
colonies which is a great sight. This has brought more Skuas in for a closer
look but with numbers of these predators low, more terns seem to be getting
back to the nest unmolested.
Arctic Skuas
At the Grutness tern colony, the problems are the common
gulls that nest in close attendance, also sheep and Shetland ponies roam
through the nest site no doubt crushing a few eggs as they go.
Let’s hope this is a good year for all seabirds the auks
need a good year but I have only seen a few young and only a few adults with
fish and also there are the Kittiwakes that have also been having a poor time
of it
