Estuaries | Caerlaverock and Solway Firth

Sensational birds

Swans feeding

Caerlaverock lies on the Solway Firth in Scotland's Border country.

This small corner of the UK where Scotland meets England is rich in nature and boasts one of the greatest goose watching spectacles in the UK.

The Solway Firth is a great place for bird watching - even the historic name Caerlaverock means 'castle of the lark'.

In spring and summer Caerlaverock echoes to the sound of Natterjack toads but in late autumn and winter, it's a great place to go bird watching.

Stunning spectacle

Barnacle GeeseCaerlaverock is the place to go to see one the UK's great natural spectacles - 12,000 Barnacle Geese fly in to the reserve in October and November every year.

The Barnacle Geese make their 2,000 mile journey from Spitzburgen in the high Norwegian Arctic.

They spend the summers breeding in the Arctic but the lack of daylight, plus the fact that their food source is covered in snow, drives them south.

They start arriving at Caerlaverock in October and by December numbers are reaching their peak.

The number of geese has mushroomed in recent years.

Back in the 1950's there were fewer than 1,000 barnacles on the Solway Firth - now there's more than 20,000.

Close up and personal

Geese at sunriseDuring the winter visitors can witness the daily spectacle of these birds spending the nights out on the mud flats - and then flying in at first light to feed on nearby farmland.

One of the best times to see the birds close up is when they're eating.

These geese are true herbivores - they will eat only vegetable matter during their entire lives.

In order to maintain their strength and put on body mass to breed again means that they have to use daylight hours to graze.

The geese can sometimes be a bit skittish and are easily disturbed, so if you're coming to have a closer look, take a bit of cover behind a hedge or a car whilst you watch them.

The story behind the Barnacle Geese's name is as intriguing as the spectacle itself.

Hundreds of years ago the geese's nests wouldn't have been seen, and it was thought that their eggs were the barnacles found on boats.

Changing environment

Solway FirthThe Solway Firth is a place of constant change due to its geographical position

Swirling currents carry large amounts of sand and mud in and out of the estuary, resulting in a complex eco-system.

The locals call this landscape 'the merse'.

The ever changing mudflats provide rich pickings for birds in the form of worms, snails, cockles, crabs and shrimps.

It's a particularly good habitat for wading birds who are ideally adapted to hunting in this landscape.

Take the Curlew, for example, with its long legs and splayed toes which means that the bird can balance on the slippery mud.
The bird's long beak reaches far down into the mud so he can pull out his meal.

Whooper Swans

Whooper SwansOne of the other birds to be found at Caerlaerock is the Whooper Swan - and the great thing is that you can get really close to them.

The swans are winter visitors and they come in their several hundreds - a daily feeding station enables human visitors to get really near to them.

The swan's yellow bills are a tell-tale sign that they're not Mute Swans which are seen all year around in UK.

Mute Swans are characterised by their bright orange bills.

The birds stay at Caerlaverock throughout the winter months and then fly back to Iceland in the spring to breed.

Badger watching

BadgerThe Solway Firth and Dumfries has very health population of badgers, and at Caerlaverock you can get very close to these remarkable creatures.

The wildlife centre runs special badger watching events called Stars and Stripes nights in specially built hides.

Badgers have a really keen sense of smell and human scent scares them off so this is the best way to see them without disturbance.

Their typical food is earthworms, but Badgers are opportunists and will feed on anything even honey and peanuts, and in winter this is a good supplement to their diets.
