The Red Squirrel Sciurus vulgaris is not always red. They range in colour from pale to black. Now very localised in Britain, they are still common across most of Europe, mainly in broadeaved woodlands but also in city parks and even gardens. Those in the latter habitats are often easy to photograph.
Before joining any wildlife watching or birding tour, wherever in the world, try to establish if the travel company you are considering booking with operates in an environmentally friendly, responsible manner.
