[Note Guidelines] Photographer's Note
On the same place where hundreds of Puffins breed on the cliffs, on the flat upper side of this former island, breeds the Skua, a great enemy of the Puffin. I saw a Great Skua flying with a young Puffin in its beak.
The skuas were attacking us while we walked very careful between their chicks.

The Great Skua (Stercorarius skua) is a large seabird in the skua family Stercorariidae. In Britain, it is sometimes known by the name Bonxie, a Shetland name of Norse origin.

Description
This is a large skua, measuring 50–58 cm long with a 125–140 cm wingspan. The adult is streaked greyish brown, with a black cap, while the juvenile is a warmer brown and unstreaked below. Its tail is short and blunt. The flight is direct and powerful. The Brown Skua's call is a harsh hah-hah-hah-hah; quacking and croaking noises have also been heard. Distinguishing this skua from the other North Atlantic skuas (Arctic Skua, Pomarine Skua and Long-tailed Skua) is relatively straightforward. The Herring Gull size, massive barrel chest and white wing flashes of this bird are distinctive even at a distance. It is sometimes said to give the impression of a Common Buzzard. Identification of this skua is only complicated when it is necessary to distinguish it from the closely related large southern-hemisphere skuas. Some authorities still regard the Great Skua as conspecific with some of these southern skuas, and as a group they have sometimes been separated in the genus Catharacta, although currently this is not commonly followed.

Breeding
The Great Skua breeds in Iceland, Norway, the Faroe Islands and the Scottish islands, with a few on mainland Scotland and in the northwest of Ireland. It breeds on coastal moorland and rocky islands, usually laying two spotted olive-brown eggs in grass-lined nests. Like other skuas, it will fly at the head of a human or other intruder approaching its nest. Although it cannot inflict serious damage, such an experience with a bird of this size is frightening. It is a migrant, wintering at sea in the Atlantic Ocean and regularly reaching North American waters. Vagrant to Mediterranean countries (e.g. Turkey).

Diet
This bird eats mainly fish, seabirds, eggs, carrion, offal, rodents, rabbits and occasionally berries. It will often obtains fish by robbing gulls, terns and even Northern Gannets of their catches. It will also directly attack and kill other seabirds, up to the size of Great Black-backed Gulls. Like most other skua species, it continues this piratical behaviour throughout the year, showing less agility and more brute force than the smaller skuas when it harasses its victims. A common technique is to fly up to a gannet in mid-air and grab it by the wing, so that it stalls and falls into the sea, where the Great Skua then physically attacks it until it surrenders its catch. Due to its size, aggressive nature and fierce defence of its nest, the Great Skua has little to fear from other predators. While fledglings can fall prey to rats, cats or the Arctic Fox, healthy adults are threatened only by greater raptors such as the Golden Eagle and the White-tailed Eagle, and more rarely by the Orca whale.

Hi Peter.
What a sweet scene taken at amazing lowest POV. Expressive poses of the birds, attractive curve of the ground and nice smooth sky with light clouds. I like timing a lot as well as exposure of the image. Well done and TFS.

Hello Peter,
Iceland seems to be a most interesting country for nature-photographer. Again a well presented shot showing birds I didn't know until now. I like your point of view from below and the vivid expression of these big Skuas.
Interesting note too.
Thanks a lot
Anne

Hello Peter,
I just return from a short holiday at the Black See and in Bucegi Mountains - Romania.
Once again a wonderful photo taken from a very good angle and POV. Exceptional quality....Excellent details. Outstanding colors and perfect focus.
You managed perfect this composition. In the next weeks I will post some photos with birds living around the Black See coast.
Thanks for sharing!

Hello Peter

Excellent photo of these large seabird species
that with the POV you choose and the action
of the birds it gives dynamism to the image,
great focus, sharpness, and details, TFS

Asbed

Hello Mr.Peter,
Natural picture of this couple.Natural moment.Natural colour and nice POV.
Thanks for sharing,
Kind regards,
Srikumar

this is a great photograph mostly because it is taken in lower angle to frame the species in action very dramatic. good work.

This candid image shows that these birds from Iceland are obviously angry, Peter. You have mentioned their aggressive behaviour in your note.
Very impressive capture.
Regards.
Ram

Dear Peter,
A wonderful capture of the aggressive Skua, and I add your work to my theme "Animals' Behaviour".
I am extremely pleased to see this wonderful photo from you. When we were in Antarctica, they stole eggs from the penguins, fought over a baby bird in mid air, and we were advised to wear sunglasses to protect our eyes from the skua's ferocious attacks dive bombing us!
The sharp details and natural colours make it a true pleasure to view your work, and I add it to my favorites.

Thanks for sharing.
Warm greetings from the Tzaneen Dam in Limpopo, South Africa

Hi Peter,

The birds are well placed in the frame. The point of view is showing the details and colours of the Great Skua. The good luminosity is bringing out the colours. Have a nice day.
