John Aitchison presents the black-throated diver. Black-throated divers are strong contenders for our most beautiful bird. Their breeding plumage with a neck barcoded in white, an ebony bib and a plush grey head is dramatic. The black dagger-like bill and broad lobed feet are perfect for catching and pursuing fish, which the divers bring to their chicks in nests on the shoreline of the Scottish Lochs on which they breed.

John Aitchison presents the white-fronted goose. Flocks of White-Fronted Geese return each year to their favourite wintering areas, the bogs and and saltmarshes of Ireland and the Severn Estuary as well as western Scotland, although smaller flocks are found elsewhere. John Aitchison recorded the musical yapping of white-fronted geese for Tweet listeners as they flew over his home in western Scotland.

John Aitchison presents the golden pheasant. Golden pheasants are native to the mountains of China where they live in thick bamboo forest. The males are brightly-coloured; gold and scarlet, with a long tail and a cape of black and orange which they use to woo the much duller brown females. From the late 1800's Golden Pheasants were introduced to many bird collections and shooting estates around the UK. Today the strongest colonies are in East Anglia.

John Aitchison presents the lesser spotted woodpecker. Lesser spotted woodpeckers are the smallest of our three woodpeckers and about the size of a house sparrow. They have horizontal white stripes across their backs, hence their old name of 'barred woodpecker'. The lesser spotted woodpecker is one of our most elusive birds. For most of the year it's relatively silent but in late February and March, males begin to stake out their territories in old woods and orchards by calling loudly and drumming softly.

John Aitchison tells the story of the parrot crossbill. The Parrot Crossbill lives only in a few native pinewoods in Scotland. When they're at the top of pine trees a view of the Parrot Crossbill is tricky, so crossbill experts use the birds' calls to tell them apart from Common and Scottish Crossbills. Parrot crossbills have a deeper call than the others.

John Aitchison tells the story of the chough. Our healthiest chough populations are in Ireland, southwest and north Wales and western Scotland. The last English stronghold was in Cornwall and Choughs feature on the Cornish coat of arms. Even here they became extinct until wild birds from Ireland re-colonised the county in 2001. Now the birds breed regularly on the Lizard peninsula.

John Aitchison tells the story of the skylark. No other UK bird is capable of sustaining such a loud and complex song while hovering high above the ground, rapidly beating its wings to stay aloft. Some songs can last 20 minutes or more and their performance is likely to be as much a territorial display as an exhibition of the male's physical fitness to impress a female.

John Aitchison tells the story of the Canada goose. These large black-necked geese with white cheeks and chinstraps are native to Canada and the USA. The first reference to them in the UK is in 1665 when English diarist, John Evelyn, records that they were in the waterfowl collection of King Charles II at St. James' Park in London.

John Aitchison presents the waxwing. Waxwings are winter visitors from Russia and Scandinavia where they breed in conifer forests. They head south to feed on berries and other fruits, and if these are in short supply on the Continent, the birds flood into the UK. It happens every few years or so and the sight of these punk-crested plunderers swarming over rowan and other berry-producing trees is sure to attract your attention.
