Revtangen OS, net by net and meter by meter

Unfortunately, Revtangen is closed for visitors for the time being, but here you can experience the station net by net and meter by meter

Spring migration has started, but unfortunately we've had to close the bird observatory for visitors until further notice. To compensate for that, we've made this virtual tour for anyone who wants to take a tour in our trapping area.


Revtangen BO is situated in Klepp (Jæren), just SW from Stavanger on the Norwegian SW coast. It is a small island of vegetation in a sea of agricultural land, just over half a kilometer from the ocean.



The trapping area is 5500 square meters, shaped as a long triangle pointing south. The North Sea road forms the boundary to the east, and along this whole there is planted spruce or Salix, or built wooden fences to screen for traffic, visibility and east winds.


The second of the two most southern nets.


The largest net system is located on the southern part of the trapping area, in a mix of spruce, pine, willow, rowan and maple. In total, 84 meters with 8-shelved nets.


At the north end of this system, 3 ponds and two canals have been excavated. Here, targeted trapping of waders and Grey Wagtail is conducted. In 2019, more than 100 waders were caught here, mostly Greenshank, Green Sandpiper and Wood Sandpiper. These are equipped with color rings (coded flags).

In the middle part of the garden, a lot of tall spruce was removed in 2013. Here, we've created a new plantation with a mixture of spruce, pine, several types of willow and birch. This vegetation has now reached a nice height for trapping.



The main layout in the north consists of four 12-meter nets in a system, two 8-shelf and two 6-shelf mist nets in a mixture of deciduous trees and rosesbushes. Playback in the dark hours is used here in the autumn, mainly to catch warblers.


This single 9-meter net in the rosebushes is one our most productive nets.

The science-building at Revtangen OS. This is the original station building, which was built in the back dunes at Revtangen in 1937 and moved to where it now stands in 1954. In 2013, it was renovated and expanded to accommodate a full school class and workshops. In this building, the meetings preceding the formation of the Norwegian Ornithological Society were held in the mid-1950s. So here is a lot of ornithological history in the old walls!


The other cabin, built in 1955, contains kitchen, living room and a couple of bedrooms.


The new ringing lab built in 2019 and the new toolshed from 2018 to the left. The station has been granted a decent upgrade the last couple of years!
