Far from just being an urban jungle, London is one of the UK\u2019s greenest cities, boasting around 13,000 species and more than 1,500 sites of conservation importance. One of Mayor Sadiq Khan\u2019s election pledges was strong protection for London wildlife and biodiversity. And he's making good on those pledges, supporting initiatives like the tree planting project across London's churches to make areas more bee friendly. So, where do you spot this wildlife in London? There\u2019s London Zoo of course, but no, that\u2019s too obvious, too pricey. \u00a0Surely it\u2019s better to have an adventure, explore a bit, take a walk on the wild side? Here\u2019s a few places we recommend, where you can spot wildlife without hurting your wallet. Just as nature intended. City birds and high flyers Over 350 species of bird have been recorded in London, at different times of the year, and you don\u2019t necessarily need to travel too far to see them. If you\u2019re short on time, you could even factor some of these places into a lunch hour or combine them with other sightseeing. Kensington Gardens is home to exotic and colourful birds. Flamingos strut up high in the roof gardens, away from the shoppers. Hang out there and you might also see the green ring-necked parakeet. Common breeds found in the other Royal Parks (Regent\u2019s Park, Hyde Park, Bushy Park, Greenwich Park, Richmond Park) are herons, crows and Canada geese\u2014all of which you\u2019re asked not to feed to control population numbers. Visiting the Tate Modern? You might want to look up before you go in, and not just at the impressively tall Switch House. The gallery\u00a0has also become a favourite hangout of the peregrine falcon, only the fastest-recorded bird in the world, no biggie. When they\u2019re not flying at around 200mph, they like to perch on tall buildings. The peregrines have made a comeback; they weren\u2019t in London for years.\u00a0But since the banning of certain pesticides, these guys have literally spread their wings from craggy clifftops to the chimney of a famous gallery. They have also been spotted across the river at St Paul\u2019s Cathedral too, so keep those eyes on the skies when you\u2019re in the area. Wetlands in London The most well-known wetland is London Wetlands Centre in Barnes, west London. But animal lovers should also take note of Woodberry Wetlands, formerly East Reservoir, which is free to visit. Sharing a name with the huge and expanding Woodberry Down Estate, Woodberry Wetlands is a stark contrast to the tower blocks that loom close by. The nature reserve is a nesting site for migratory and breeding species. Springtime sees the return of swallows and sand martins. Buzzards and red kites take over the skies at this time year too. Once the sun goes down, out come the bats. The Woodberry Wetlands has the tiny (and one of the UK\u2019s most common species) the pipestrelle, as well as the far larger noctule and the brown long-eared bats. You can also spot leopard moths, red admiral butterflies, dragon flies, damselflies and populations of newts, toads and frogs too. Rivers and canals Near to the Woodberry Wetlands, Hackney Marshes is an area of grassland, and one of the largest areas of common land in London. Apart from excitable dogs on walks, you can go on bat walks and invertebrate walks. Fish species recorded in the River Lea include bream and perch. Closer to the centre of the city, the former coal drop between King's Cross and St Pancras has been transformed into a new urban nature reserve. Alongside the Regent's Canal, Camley Street Natural Park\u00a0has meadows, marshland and wetland habitats for creatures to dwell in. Explore to find kingfishers, common frogs, bats and mallards among other species making their homes there. There are viewing points along the canal and outdoor eating area, so pack some lunch if you want to make the most of your time there.
