NRBO was established in 1987 to study and record the migrant birds that pass through Orkney's most northerly island each year.
COVID-19 UPDATE: The Observatory is open again and welcoming visitors, though just one customer at a time in our shop, and please observe good hand hygiene and social distancing measures in place.
The number and variety of birds that arrive here on migration in Spring and Autumn can be spectacular, and North Ronaldsay is well-known as one of the best birdwatching sites in the country. The observatory also provides a variety of comfortable accommodation, including guest house, hostel and camping area, and a shop with groceries and other goods for visitors to the island.
There is a cafe at the Observatory, open between 12pm and 2pm, and evening meals can also be arranged.
