The Garden seemed full of spring migrants this morning! I heard at least three, possibly four, different Willow Warblers around the Chinese Hillside and Pond areas. A Chiffchaff arrived on 19 April and there are now at least two males singing, plus at least three Blackcaps. Swallows were first seen in the Botanics on 18 April, which is unusually early for the Botanics but about normal in the wider Edinburgh area. Spring has definitely arrived!
