Starlings have been on the decline for decades and as a result are on the red list for conservation, requiring the highest level of protection. They are considered a pest species because of the sheer numbers that flock and roost together, causing an unsightly mess and creating a lot of noise. They love to nest in a roof or loft but other than noise, they don’t do a lot of damage.
Measures for dealing with starlings are limited to deterrents and can only be installed after the birds have finished nesting. Their breeding season is most active in May and is short but they can breed more than once. In a domestic property bird gels and bird spikes are usually enough to prevent the birds from roosting.
