White-tailed Eagle and Corncrake: Birdwatching in the Scottish Hebrides, Part 1

Dr. James J. S. Johnson

Let them give glory unto the LORD, and declare his praise in the islands.

Watching coastal birds is a favorite pastime in the Outer Hebrides, according to Outer Hebrides Tourism.  Having visited some of the Inner Hebrides, with marvelous birdwatching opportunities (including puffins!), I am not surprised.

The Outer Hebrides archipelago is a unique island chain perched on the North Western edge of Europe. Here the landscape ranges from white sand beaches and flower covered machair grasslands to barren hilltops, fjord like sea lochs and vast peatlands. Wildlife is abundant and birds of prey are a particularly visible feature of the open landscapes . . . Spring and autumn are the best times to spot migrating birds in the Outer Hebrides with large numbers of seabirds passing up and down the coasts of our islands on their way to and from northern breeding grounds and wintering grounds to the south.  These are both exciting birding seasons in the Outer Hebrides when almost anything can turn-up but the highlights of spring and autumn birding in the Western Isles include the passage of Skuas offshore and the flocks of geese and whooper swans passing overhead. Visit in the spring and summer to see the Outer Hebrides seabird breeding colonies of terns and gulls, which be found scattered along the coastline on headlands, beaches, islands and sand dunes.  Although most breeding colonies are found offshore they will travel long distances to feed and birdwatchers can often see seabirds in the Western Isles from the shore.  Spot Gannets in the Outer Hebrides as they make their spectacular dives after fish and keep eyes open for Black Guillemot, Guillemot, [Atlantic] Puffin, Razorbill and Fulmars, as all are common island birds.

Some of the coastal birds that frequent the Outer Hebrides include shorebirds (such as Black-tailed Godwit, Curlew Sandpiper, Dotterel, Dunlin, Jack Snipe, Little Stint, Oystercatcher, Pectoral Sandpiper, Purple Sandpiper, Redshank, Ringed Plover, Ruff, Sanderling, Turnstone, Heron), seagulls (such as Glaucous Gull, Iceland Gull, Lesser Black-backed Gull, Greater Black-backed Gull), as well as various ducks (such as Eider, Goldeneye, Black-throated Diver, Great-northern Diver, Red-throated Diver, Red-breasted Merganser, Shelduck, Shoveler, Long-tailed Duck), plus Shag and Cormorant, Atlantic puffin, Northern Gannet, geese (Dark-bellied Brent Goose, Greylag Goose), Mute Swan, plus a mix of passerine songbirds (such as Barred Warbler, Blackcap, Bluethroat, Brambling, Chiffchaff, Common Crossbill, Common Whitethroat Warbler, Corn Bunting, Dunnock, Hawfinch, House Martin, House Sparrow, Meadow Pipit, Pechora Pipit, Pied Flycatcher, Redwing, Rose-colored Starling, Stonechat, Yellow-browed Warbler), the Ring Ouzel, the ever-versatile Woodpigeon, and more!

The Hebrides, formerly known as the “Western Isles”, are wildlife-watching venues.

With the islands enjoying one of the last untouched natural landscapes in Europe, wildlife in the Western Isles is some of the finest in the world, with Outer Hebrides animals and plants all at home in their surrounding without fear of poaching, pollution or disturbance.  Wildlife watching in the Outer Hebrides offers a glimpse into a time almost forgotten by the rest of the world, where the white -tailed eagle soars over the rugged coastline as red deer roam proudly over the peaty moorlands and [river] otters swim in many sea lochs.  Much of the wildlife in the Western Isles is unique and protected, meaning that visitors enjoying Scottish island nature breaks here can enjoy pursuits as diverse as spotting minke whale in the sea around the Outer Hebrides and eagle watching in the sky. 

[The Outer Hebrides] are a popular destination for birdwatching in Scotland, as birding in the Western Isles offers opportunities to see everything from birds of prey to seabirds and waders. Look out for the Bird of Prey Trail which spans the Outer Hebrides with location markers for the best places to see birds of prey. As well as this, the Western Isles are the summer home to two thirds of the elusive British corncrake population from April to September.

In the above quotation the White-tailed Eagle (a/k/a “Sea Eagle”) is mentioned; this raptor is Great Britain’s (and thus also Scotland’s) largest bird of prey.  It habituates almost all of Scotland, including the Inner and Outer Hebrides.

The White-tailed eagle is one of the largest living birds of prey. It is sometimes considered the fourth largest eagle in the world and is on average the fourth heaviest eagle in the world. White-tailed eagles usually live most of the year near large bodies of open water and require an abundant food supply and old-growth trees or ample sea cliffs for nesting. They are considered a close cousin of the Bald eagle, which occupies a similar niche in North America. The adult White-tailed eagle is a greyish mid-brown color overall. Contrasting with the rest of the plumage in the adult are a clearly paler looking head, neck and upper breast which is most often a buffy hue. The brownish hue of the adult overall makes the somewhat wedge-shaped white tail stand out in contrast. All the bare parts of their body on adults are yellow in color, including the bill, cere [nose-like part of upper bill], feet, and eyes.

Watching these sea eagles catch fish in their talons, as they wing to, near, and then away from the seawater surface, is much like watching Bald Eagles catch fish in the coastal seawaters of Southeastern Alaska.  [See video clip of a Sea Eagle catching fish, at rspb.org.UK – website of the Royal Society for the Protection of Birds.]

White-tailed eagles are powerful predators and hunt mostly from perches, in a “sit-and-wait” style, usually from a prominent tree perch. Fish is usually grabbed in a shallow dive after a short distance flight from a perch, usually with the eagles only getting their feet wet. At times they will also fish by wading into shallows, often from shores or gravel islands. When it comes to non-fish prey, White-tailed eagles often hunt by flying low over sea coast or lake shore and attempt to surprise victims. [emphasis added]

[Quoting “White-tailed Eagle”, Animalia, https://animalia.bio/white-tailed-eagle .] 

These coastal raptors mostly eat fish.  However, they also eat waterfowl and small mammals (such as rodents).  During winter they eat lots of carrion.

In previous centuries the White-tailed eagle populated the coasts of Scotland, but it was hunted to extirpation in the A.D.1920s.  However, it was conservationally re-established on Rhum in A.D.1975, and (thankfully) it has since re-colonized (beyond 25 breeding pairs, apparently) many of the indented inlets of the coastal strands of Outer Hebrides islands, including Harris, Lewis, and South Uist. 

White-tailed Eagles are large birds (2-to-3 feet, from bill-tip to tail-tip; 6-to-8 feet wingspan; 9-to-16 pounds), famous for eating fish (such as salmon, trout), yet they also prey on rabbits and hares, geese, available seabirds (such as fulmars and petrels), and lamb carrion.  Like their Golden Eagle cousins—which reside in the Hebrides—these eagles establish and defend territories for their families.

Other birds of prey, habituating the Outer Hebrides, include two types of owls, the Short-eared Owl and the Long-eared Owl.  Other birds of prey include hawks (such as harriers, sparrow hawks, and ospreys) and falcons (such as kestrels, peregrines, and hobbies), which routinely find and consume rodents (such as voles).  Other birds of prey, sometimes observed, include Buzzards, Snowy Owl, and Gyrfalcon. 

However, in contrast to such carnivorous raptors, consider the common Corncrake.

The chicken-like Corncrake is a migratory rail that frequents grassy parts of Hebridean islands, as well as Scotland’s semi-marshy floodplain grasslands (dominated by grasses or sedges) and coastal wetlands (such as nettle beds, iris beds, and reed beds), yet the Corncrake prefers the tall plant-cover of farmed crop-fields (such as hayfields, fields of wheat and other cereals, and clover meadows).  This rail arrives from mid-April and stays for breeding and beyond, till August or September.  After that the Corncrake migrates to North Africa, for over-wintering.

The Corncrake’s appearance somewhat resembles a young Grey Partridge (or somewhat like a moorhen or coot), yet it is almost as small as a blackbird.

Plumage softly but richly coloured, with pale grey face, fore-neck and breast, yellowish-buff upper parts, lined with cream and spotted or streaked blackish-brown, chestnut wings ‘catch fire’ in flight, barred white flanks.  Bill and legs dull pink.  Flight typical of [rail] family, loose-winged and clumsy; usually escapes by running into dense cover. 

[Quoting Roger Tory Peterson, Guy Mountfort, et al., A Field Guide to Birds of Britain and Europe (Houghton Mifflin, 1993), page 93.]

Because Corncrakes (a/k/a Land Rails) routinely reside in grassy fields, where photosynthetic biomass productivity is high, they have a smörgåsbord of seeds – as well as other foods, available just for the taking.

Besides seeds these rails eat bugs (especially cockroaches and beetles, including dung beetles), fly larvae, termites, ticks, spiders, dragonflies, earthworms, grasshoppers, slugs, snails, weevils, and even small frogs. [Regarding the diet of Corncrakes, see further Suzanne Arbeiter, Heiner Flinks, et al., “Diet of Corncrakes Crex crex and Prey Availability in Relation to Meadow Management”, ARDEA, 108(1):55-64 (April 24, 2020), posted at https://doi.org/10.5253/arde.v108i1,a7 . ]

Corncrakes themselves must be careful—they serve as prey to other animals, including mustelids (mink, ferrets, and river otters), foxes, larger birds (such as white stork, harrier hawks, seagulls, and corvids, especially hooded crows).

Wonderful birds are there to be seen, in the Outer Hebrides (Scotland’s “Western Isles”).  If you get the opportunity, go see them! 

Meanwhile, appreciate that they are there, living their daily lives—filling their part of the earth—glorifying their Creator (Isaiah 42:12).

    • Thanks, Lee — it’s good to know that modern technology, especially cyber-technology, can give us access to places we can’t physically travel to, and thus also to birds we otherwise won’t see in this life.

  2. Excellent post JJ SJ, very descriptive narrative, makes you want to be there. These were the parts of Scotland we never saw. Beautiful images of these birds. The White-tailed Eagle is most impressive, and of course to see a Puffin would be an immense delight.

    • Thanks, Ashley — your website [ AussieBirder.com ] is very descriptive itself, so I recommend that Leesbird’s readers check your website out too! By the way, speaking of Puffins, in the soon-coming (D.v.) issue of ACTS & FACTS, i.e., the January-February issue (for A.D.2022), I have an article on Puffins. IT should be online in about a week or so [ http://www.icr.org ]. Meanwhile, please have a wonderful CHRISTmas!
