Birds have the best view of nature, and Earthflight is the first programme to take you along with them on a soaring ride over spectacular scenery.
The BBC's latest nature show is hot on the heels of David Attenborough's Frozen Planet and has some high expectations to meet, but David Tennant does a fine job curating this birds-eye view of the world.
The first episode of the six-part voyage, which focused on North America, was a lesson in intelligence, brotherhood and survival and was given rave reviews last week. The Telegraph wrote: "Footage of bear cubs torn between feasting and continuing to hunt, the carnage of upturned horseshoe crabs on Delaware Bay, and of dolphins, flushing pink with excitement on the marshlands of South California stayed with me long after I'd turned off my television."
Meanwhile, the Independent said: "The camera appears to fly alongside a snow goose, peering up into its wingpit as it languidly beats its way northwards. Apparently, episode six will reveal all, but in the meantime we'll just have to marvel at what they've managed to achieve."
This week the show (BBC One, 8pm) takes us over Africa's landscape and wildlife, showing Cape gannets joining sharks, dolphins and whales as they feed off shoals of sardines. Also featured are kelp gulls following the trail of great white sharks, eagles diving for fish in the Zambezi river and vultures witnessing the wildebeest migration on the Serengeti.
The next three weeks are no doubt going to include chatter about the antics in the Celebrity Big Brother house. If you want to have a clue who people are talking about, or nature's not your bag, the launch show of Channel 5's CBB begins at 9pm with promises of screaming, fake tan and some hilarious introductions between celebrity egos.
Stars including Natalie Cassidy, Kirk Norcross, Frankie Cocozza, Page 3 girl Nicola McClean, comedienne Ruby Wax, Irish model Georgia Salpa and Denise Welsh are all rumoured to be spending weeks cooped up in the Elstree compound that's been transformed into a Swiss lodge.
