With the scientific name Circus aeruginosus, the marsh harrier is also popular as the Eurasian marsh harrier. The population distribution of these birds can be traced across several countries in Europe and Asia.
The declining population of these birds was a major concern.
Their numbers were severely impacted mainly due to the extensive use of organochlorine pesticides (like DDT) that made their eggshells fragile thus resulting in unsuccessful breeding and reproduction.
Additionally, unethical human practices like disturbing bird nests, poisoning, and hunting had rendered these birds vulnerable. To draw an end to these unscrupulous practices, the Nature Conservation Act 2004 (Scotland) and the Wildlife and Countryside Act 1981 (the UK) were put to force.
The act was implemented to ensure that the marsh harrier is protected from the aftermath of illegal actions. Perpetrators accused of damaging the bird's nest or harming the eggs or even a juvenile marsh harrier were to be penalized with a hefty amount of £5000 ($6120.5) and sometimes with a six-month prison term.
These measures helped to curb the malpractices and revive the numbers of the marsh harrier.
