The European roller (Coracias garrulus) was a common breeder in the Danube basin (Bohuš 2002, 2011) and a decline started from the 1950s. The use of pesticides (mostly against different Orthoptera- species) was an important factor in the extinction (Kiss & Tokody, 2017). Following a moderate decline during 1970-1990, the species has continued to decline by up to 25% across Europe during 1990-2000. Overall European declines exceeded 30% in three generations (15 years). Data of electrocuted European rollers at power lines have been reported in Csibrány 2016, Demerdzhiev et al. 2014, Demeter et al. 2018).
