BASS ROCK (S.E. SCOTLAND) REVISITED. AUGUST 2019.

Recommended Posts

In June 2018 I posted a short trip report on a visit to the world renowned Gannetry on Bass Rock, southern Scotland. Without going over old ground (see original report Bass Rock. Firth of Forth. Scotland. May 2018. under Worldwide trip reports), I mentioned that I hoped to return this year but later in the breeding season when adult  pairs would be with their chicks. I also mentioned in my original report the unacceptable amount of litter on the island and that it was impacting on the wellbeing of a few of the Gannets. Despite sending two emails to The Seabird Centre offering to help clean up parts of the island, once the birds had left in October, my offer was not taken up. As I was keen to see the adults with chicks I made arrangements to make a landing on the 29th of July of this year, this was cancelled the day before due to inclement weather. We have enjoyed a pretty lousy summer in Scotland this year. Very few landings have taken place during 2019, so visitors particularly travelling from abroad take note that whilst the experience on the rock is outstanding and well worth doing, the few landings that are arranged each year are often cancelled at the last minute. However I was able to make a rescheduled landing on Monday 26th August, despite it being overcast the sea was calm. I am pleased to say the situation on the rock regarding litter had significantly improved. Someone had clearly been busy and I applaud their efforts. At the time of my 2nd visit there was approximately 75,000 breeding pairs of Northern Gannets and a huge number of chicks at various stages of development on Bass Rock, it was the chicks that had prompted my return. Bass Rock is the largest single stack breeding population of Northern Gannets in the world and accounts for a sixth of the total population. The population on Bass Rock has increased by 24% in recent years, however only around 30% of chicks reach adulthood. At around 13 weeks the chicks dive off the ledges into the sea where they develop their fishing and flying skills, if they survive the dive. Juvenile Northern Gannets are known to travel vast distances during the migration period that follows in October particularly during their first year, much further than adult birds.They usually return to their place of birth initially as a non-breeding juveniles (2-3 years) before finding a suitable mate at 4-5 years of age.  What also drew me back to Bass Rock is the sheer number of birds and just how close you are able to get to them, it is impossible to describe in text or capture in an image the Bass Rock experience, it is simply awesome.

On arrival, the welcoming party.

Beauty and the beast, you decide.

Another adult with a chick, 5 minutes before this was taken, we thought this chick was dead. The chick is around 4-5 weeks old, they are constantly being pecked by both their parents and other Gannets, and believe me a Gannet peck is none too pleasant an experience. As you can see the nest is not very impressive, last year many of the nests contained plastic debris.

A juvenile in flight, it has not quite got full adult markings therefore possibly about 2-3 years old. Aerial manoeuvres to resolve an itch!

Which has the largest carbon footprint?

It is a great place to practice taking images of 'birds in flight'.

The sheer concentration of birds is impossible to describe.

Landing always causes problems for the neighbours in the vicinity of the chosen spot. Watching them find the correct site is fascinating. They all approach from the same direction, hundreds at a time and often have to circle the island several times to get their bearings. Then when they have located the right nesting area it is flaps and undercarriage down and more often than not a crash landing.

It usually results in the adult birds then attacking each other and if there is a chick about that gets the treatment as well. Chaos reigns everywhere. The whole colony appears to be in a state of constant conflict. I am sure there is some sort of method in the madness, but it defeats me.

We took this chick back to the mainland, our guide was of the opinion it had been deserted. It would be well taken care of and then released. 

5H1A0834.jpg.603e1caad1157bfe10b60f8cb017cdec.jpgThe more usual Bass Rock trip involves circumnavigating the island without a landing, as in the dinghy in the centre of the image. These trips are very popular and can be taken throughout the season. Our trip (landing) lasted around 5 hours with 4 on the island. The group size was 5 plus a guide. I really enjoy a visit to Bass Rock it must be one of the best birding experiences on the planet and I will no doubt return again next year. During my time on the rock the only other species noted was two Herring Gulls, this is indeed Northern Gannet Central.

 

TO FOLLOW: An interesting sequence of images showing a chick being fed by one of its parents, not for the squeamish.

I had another visit to the Isle of May in late June from where you see a constant stream of Gannets flying backwards and forwards from Bass Rock, and on occasions diving in to the sea nearby. They never fly over the island though even though it's not very big. They do rib boat trips from North Berwick both to Bass Rock and the IOM.

Lucky you to make a landing.  Most interesting perspectives from the contrails in the background to the extreme closeup accentuating the marble eyes.  Glad the chick lived and I'll be awaiting the next installment, checking my squeamishness.

love the close-ups of the chick but was awed by that upturned head image - the details are vivid.
