September 10th-A brilliant day for birds continued….

As the tide began to return to the shore, every exposed rock in Penrhyn Bay was occupied by beady-eyed Cormorants.

Black-headed gulls also waited.

It seemed Rhos Point was the place to be for seabirds and waders today. In the time I have lived here I have never seen as many here all at once. I got there an hour or so before high tide, which is one of the best times to get close views of the birds waiting for their evening meal to be delivered. But as there were also such a large number of terns and gulls swimming on the sea’s surface and flying low over it, there must have been fish there drawing them in, perhaps a shoal of small fish, sprats or whitebait¹.

The tideline at Rhos Point was crowded with Herring Gulls, Black-headed gulls and Sandwich Terns. A woman arrived with two dogs and stood and watched as they chased along close to the water’s edge, sending many of the birds skywards. I will resist having a rant about that, but it troubles me that people think it’s OK to allow their dogs to do that.

Whilst waiting to see if the upped birds would return and re-settle I scanned along the sea edge to see what else might be waiting there. There were a whole host of Oystercatchers, trickier to see when their bright orange-red bills are tucked away whilst they rest. A few little Turnstones were dotted amongst them and then a larger bird at the back of this group, fast asleep with its head tucked well down – a duck for sure, maybe a female Red-breasted Merganser? Identifying ducks is not one of my strong points even when I have a good view of them.

Standing in the shallow water were a good number of Redshanks

and more Black-headed gulls.

A few Sandwich Terns were in amongst this group of Redshank, Turnstones & black-headed gulls.

I found only one Ringed Plover, although there could well have been more.

A large number of Sandwich Terns occupied a finger of exposed rocks with a few Oystercatchers and gulls, with many more gulls bobbing around on the surrounding sea.

The Sandwich Terns, here in large number today were noisy and excitable, with groups taking off and settling again in spots a few metres away along the shoreline. Some will remain here for the autumn and winter, but others will move on.

Their association with Black-headed Gulls is one I’ve seen many times.

There’s usually a crow or two waiting for the tide’s incoming feeding opportunities too.

Amongst the multitude of gulls swimming around were several Red-throated Divers – difficult to keep in sight as they dive frequently and disappear just as you think you may have one in focus, but a man close by with a brilliant telescope patiently located them and let me have a close-up look. Still not easy as you can’t predict where they’re going to pop up again, but I managed a couple of spots – what an exciting treat. At one point I thought I may have got lucky with a view of a group of six birds, also swimming and frequently diving and disappearing beneath the surface, but they turned out to be Razorbills, not quite as ‘special’, but still lovely to see.

They separated and mostly stayed too far out to see well without the aid of binoculars or a telescope, but as the tide progressed inwards, so also did one of the birds, allowing me a much better view of it.

As I watched the razorbill, the duck also took to the water.

I’m fairly confident it was a female Red-breasted Merganser. (The female Goosander looks similar but brown colour of head extends around neck leaving just a white chin). On this bird the white of the throat seems to extend down the front of the neck.

¹ Whitebait is a collective term for the immature fry of fish, typically between 25 and 50 millimetres long. Such young fish often travel together in schools along the coast, and move into estuaries and sometimes up rivers.

Bird Study: Cormorant

coastal birds, Cormorant, phalacrocorax carbo

Cormorants are breeding residents here and since I arrived in July sightings of the birds flying or swimming in the sea have been consistently frequent, but in recent weeks their numbers have increased manyfold. Numbers of them now joined the ranks of oystercatchers and gulls that line the sea-edge as the tide comes in, and they can be spotted on the rocks of the harbour breakwater and perched on top of available posts. There are almost always a few to be seen on the lower reaches of the Little Orme, but now there are many, their black forms punctuating the pale limestone.

Cormorant – Phalacrocorax carbo

Scientific name from: Greek: phalakros=bald + korax=the raven and Latin: carbo=charcoal

Common name: definitions of ‘Cormorant’

(n.) A voracious eater; a glutton, or gluttonous servant.
(n.) Any species of Phalacrocorax, a genus of sea birds having a sac under the beak. Cormorants devour fish voraciously, and have become the emblem of gluttony. They are generally black, and hence are also called sea ravens, and coalgeese.

The Cormorant's flight is strong and purposeful

A large and conspicuous waterbird, the cormorant has an almost primitive look about it.Its long neck makes it appear almost reptilian, particularly when swimming with the bulk of its body submerged.

Some of the Cormorants dotted across the base of the Little Orme

Cormorants are coastal rather than oceanic birds, and many have colonised inland waters – in fact the original ancestor of cormorants seems to have been a fresh-water bird, judging from the habitat of the most ancient lineage. They range around the world, except for the central Pacific islands.

All are fish-eaters, feeding mainly on small eels and flat fish. They dive from the surface of the water. All four toes on each foot are webbed which aids them in swimming and in pursuing fish underwater.

Cormorants are supreme fishers which can bring them into conflict with anglers and they have been persecuted in the past, although some enterprising Japanese and Chinese fishermen employ the bird’s expertise to assist them, training one species of the birds to dive and catch fish for them.

A juvenile Cormorant with partial paler underparts still present.

The birds are often seen standing with their wings held out to dry and the reason for that is a bit of a mystery and the focus of study. It seems strange that a bird that spends much of its time in the water should need to dry their plumage and all cormorants have preen gland secretions that are used ostensibly to keep the feathers waterproof. It has been variously stated that cormorants have waterproof feathers; they have water permeable feathers; that the outer plumage absorbs water but does not permit it to penetrate the layer of air next to the skin; that it aids thermoregulation,digestion, balances the bird or indicates presence of fish. However, a detailed study of the Great Cormorant concludes that it is without doubt to dry the plumage. (extracts from article in Wikipaedia)

Cormorants in human culture

Cormorants feature quite commonly in heraldry and medieval ornamentation, usually in their “wing-drying” pose, which was seen as representing the Christian cross. For example, the Norwegian municipalities of Røst, Loppa and Skjervøyhave cormorants in their coat-of-arms. The species depicted in heraldry is most likely to be the Great Cormorant, the most familiar species in Europe.
In 1853, a woman wearing a dress made of cormorant feathers was found on San Nicolas Island, off the southern coast of California. She had sewn the feather dress together using whale sinews. She is known as the Lone Woman of San Nicolas and was later baptized “Juana Maria” (her original name is lost). The woman had lived alone on the island for 18 years before being rescued.
The bird has inspired numerous writers, including Amy Clampitt, who wrote a poem called “The Cormorant in its Element”.
The cormorant was the disguise used by Satan in Milton’s Paradise Lost. The cormorant was significant as a symbol of “true Life/ Thereby regain’d,” and was ironically used by Satan. Satan sat on top of the Tree of Life as a cormorant in his first attempt to deceive and tempt Eve.
There is a cormorant portrayed in the first of the fictional paintings by Jane Eyre in Charlotte Bronte’s novel, representing Blanche Ingram.
The mythical ‘Liver Bird’ symbol of Liverpool is commonly thought to be a cross between an eagle and a cormorant.
