I heard my first Chiffchaff of the spring singing on the reserve this morning and later in the day saw my first Brimstone butterfly of the year. The Brimstone was a sulphur-yellow male flying along a ride where some trees were felled late last year to allow more light in and a scrubby edge to develop. The reserve is a good place to see Brimstones because there is quite a lot of alder buckthorn, the foodplant of its caterpillars.
