Wildlife can thrive in city centres, as well as in reserves, wild moors and remote islands; you just need to know what to look out for, say our tipsters
Cuckoos, kingfishers, water voles, marsh harriers, seals and fantastic views from the coffee shop: inside the M25! Take a bow, Rainham RSPB reserve. A two-mile walk around the reserve (which is only a 20-minute stroll from Purfleet station) yields rich rewards, and even spectacular views of Eurostar trains. Spring is particularly noisy, with warblers of all sorts, and winter, with large flocks of lapwings and a gazillion ducks, is spectacular. There are also rare bearded tits, comfortable hides, simple walking, kids’ events and a great coffee shop with a small playground. The Thames views are wonderful: the sun filling the cafeteria, which has huge windows over the reserve and the river with basking seals, makes one forget the nearby big smoke.
