Crossbills are finches with large heads and bright colours: the males are red and the females are olive green. What makes them so unusual is that the tips of their beaks are crossed over; allowing them to rip into pine cones and extract the seeds. Different species of crossbills have different sized bills, which have evolved in association with the species of cones they eat. The Common Crossbill is found across the UK all year round and its numbers have been boosted by the planting of commercial conifers such as pine and larch. A real prize for birdwatchers is the larger and much rarer Parrot Crossbill, which has a very deep bill and can tackle the biggest and thickest cones. Presenter Trai Anfield and ornithologist Ian Newton, who has studied the movements of crossbills, take the rare opportunity to track down this flock, which probably irrupted from the breeding forests in Scandinavia.

In 1985, a dragonfly landed on Ruary Mackenzie Dodds. Up until this time, he had never had much interest in insects, but so astonished and bewitched was he by "this beautiful" insect which had landed on his shirt, that he decided to find out more about dragonflies and in time that led to the founding of The Dragonfly Project to enthuse and educate people about dragonflies. In August 2013, Ruary 'handed over the baton' of the Dragonfly Project to The British Dragonfly Society who will continue this work alongside their own work to conserve dragonflies and their wetland habitats, but Ruary's eagerness to share his enthusiasm for these insects continues "I don't know what it is about dragonflies ... they absolutely electrify me ... I get so excited when I see them in the air". In this programme, Ruary searches for dragonflies and their larvae amongst the reeds and watery places of Wicken Fen in Cambridgeshire and offers a fascinating insight into their lives.

Each year the reedbeds of the Somerset Levels become the winter home for hundreds of thousands of starlings. Making their way from across the UK and Europe these birds have found a safe haven to roost with plenty of food nearby. The famous evening murmuration, fantastic formations of huge flocks of starlings coming in to roost, brings hundreds of visitors to the levels each winter. But far fewer people see the spectacle of the dawn eruption when the starlings take off en masse to start their day foraging in the surrounding fields. Simon Clarke of Natural England talks Trai Anfield through the spectacle on Shapwick Heath. When it is all over and three quarters of a million starlings have departed for the day, thoughts turn to the reedbed and the effect the presence of so many birds has on their winter roost site and the animals they share it with.
