I read a warning on an Australian website asking for all sightings of starlings to be reported, not because they were concerned about the welfare of the birds, but because”
The common starling (Sturnus vulgaris) is one of the most invasive bird pests worldwide, having established populations in many countries outside its natural range.
In England, Starlings are protected under the Wildlife and Countryside Act 1981, which makes it illegal to intentionally kill, injure or take a starling, or to take, damage or destroy an active nest or its contents.
The Starling is on the Red List of Birds of Conservation Concern.
I will let you draw your own conclusions.
