Osprey Solutions, LLC provides expedited nest management services to minimize risks associated with bird nests on power poles, light poles, cell towers, bridges and industrial equipment. Our nest management strategy is based on the concept of coexistence, using effective, non-lethal, nest excluder devices to completely exclude nesting attempts at undesirable sites to ensure bird protection and reliability of industry operations while simultaneously accommodating the nesting birds by providing a suitable, alternative nesting platform nearby. Contact us to develop a site-specific solution tailored to your infrastructure and landscape options using Google Earth satellite views or an on-site meeting.
