The National Trust is encouraging gardeners across the UK to do their bit for wildlife, particularly birds, during the colder months. With temperatures dropping and food becoming harder to come by, your garden could make all the difference to these vulnerable creatures. So, how can you help them survive the chill? Don’t worry, it's not difficult. First things first – food and water. While it may be tempting to let your feeders run dry or skip the birdbath for the season, birds need our help now
