History

The first record for D&G was a daytime observation of one at Mabie Forest (VC73) on 30 May 2023. This was quickly followed by one to light near Whithorn (VC74) on 20 June 2023. This species is a resident breeder in northern Scotland but also a sporadic migrant. These two D&G records are both likely to have been migrants.
