A celebration of the importance of the British countryside.

This short ends with a warning that the birds helped "to preserve the leafy loveliness of our English countryside. We should therefore protect the warblers."

The first in the Secrets of Life series of short films.

The film tkes us to the North of England to follow the migration of the black-headed gull down to London. There, the narrator asks viewers to "listen to their gossip", before demonstrating the bird’s flight in slow motion. We see a polecat feasting on gull eggs, and then a man collecting the eggs for human consumption, with the film telling us that they are considered a “delicacy” in London. Indeed, according to the British Trust for Ornithology, around 300,000 gull’s eggs were sold every year in Leadenhall Market in London during the 1930s, when London Visitors was made.

Go with the flow: to gentle but spellbinding effect this innovative natural history film glimpses marine life astride rising tides at Millport on the Isle of Cumbrae. Urchins, lugworm, weaver-fish and crabs are the shy-but-elegant stars coaxed onto the screen (with the assistance of Millport’s local research station) for this archetypal edition of Gaumont-British Instructional’s 1930s cinema series Secrets of Life.

"If they were as rare as orchids we would probably rave about them" opens this film in the Secrets of Nature series, directed by the prolific Mary Field. The mesmerising time-lapse photography is offset by a jokey commentary voiced by EVH Emmett, then best known as the voice of the Gaumont newsreel. The flippant tone is exemplified by his comment on the range of responses to dandelions: "Some gardeners tear up the lawn and lay crazy paving, some tear up a high cliff and jump off".

King Penguins are first seen in their natural habitat, the Antarctic, after which we see them in the Edinburgh Zoo. With slow-motion pictures we see how they swim with the use of their flippers and feet. Their mating and incubating of their eggs and later, the hatching of them; the rearing of the young at various stages of their growth are also shown.

The Secrets of Life series (1934-50) may not conform to modern expectations of nature filmmaking, inclined as it is towards giving cute fluffy creatures human names and characteristics. But it couldn't be accused of shielding kiddies from the harsher realities of the food chain, as this exercise in ruthless Darwinism demonstrates to unintentionally hilarious effect. A more than usually eccentric narrator introduces us to the newborn bunny quartet of Donald, James, Charles and Clifford, but as the film's title gives away, "the boys" aren't all long for this world as they face an assault course of hungry owls, predatory badgers, shotgun-happy gardeners and aerial bombardment (no harm in a little anti-Nazi detour, this is 1942 after all).

History - and natural history - filmed on location in Selborne, East Hampshire. This unusual edition of the long-running series Secrets of Life tells the story of the village's famous son, Rev Gilbert White, whose 1789 book The Natural History and Antiquities of Selborne is a classic of natural history. The film follows in his footsteps, with camera rather than quill in hand, focusing on nature but also taking in views of the village and its human inhabitants. The ingenious close coverage of bird, reptile and other wildlife was the stock-in-trade of the filmmakers at Gaumont-British Instructional, producers of the series. Under the direction of the redoubtable Mary Field, the behind-screen talent here includes legendary 'cine-biologists' Percy Smith and Oliver Pike. A tribute by one generation of pioneering naturalists to another, it's a quietly moving film in spite of its clipped English reserve - or perhaps partly because of it.
