In Montpelier Park this morning a Willow Warbler showed well. I guess it must have been another migrant recently arrived rather than the same individual I've seen on previous occasions. There was also a singing Blackcap nearby. At the station, two new butterflies for the year - a Small White and a couple of Large Whites! This brings the total of butterfly species seen at the station this spring to 5, which isn't bad! Also at the station were a pair of Robins carrying food into a nest hidden in the undergrowth!
