HiAs from 1985, the OWG has held annual meetings, with the sole exception of 1988. In 1986, Tengmalm's owl and pygmy owl were the subjects of a national conference that took place in Mitwitz castle. In the same year, the OWG published the results of detailed investigations conducted from 1974 to 1984 into the habitat requirements of the little owl in Germany. The first conference of owl experts from the whole of re-united Germany was held in Homburg an der Saar in 1990. From 1990 onwards, there was a close cooperation with the Association for the Reintroduction of the Eagle Owl (AzWU). As from 1994, the OWG took over the activities of the National Working Group (BAG) for Owl Protection in the Federal Committee (BFA) for Ornithology and Bird Conservation of the NABU. In 1995, the OWG was co-organizer of the conference held in Bad Blankenburg on Tengmalm's owl and pygmy owl in Germany. Since 2000, the OWG has maintained a website with the address www.ageulen.de.

In 2000, the OWG's first international conference took place in St. Andreasberg in the Harz district, with speakers and participants from all over Europe. This, the 2nd European Owl Symposium, attracted 220 owl experts. The conference languages were English and German. There were 44 lectures and 24 posters. Besides 30 contributions from Germany, there were some from Finland (6), Switzerland (6), Belarus (4), the Czech Republic/Slovakia (4), the United Kingdom (3), the Netherlands (3), Denmark (2), Italy (2) Poland (2), Belgium (1), Bulgaria (1), France (1), Norway (1) and Slovenia (1). In 2003, the OWG hosted the third European Symposium on The Ecology and Conservation of European Owls at the Inatura Centre in Dornbirn, Vorarlberg. This meeting attracted a particularly large number of Austrian and Swiss ornithologists.

The Owls Working Group brought out its first Info  in DIN A5 format in 1975. After issue No. 37, this Info became the group's newsletter in DIN A5 format. This OWG newsletter was transformed in 1993 into the journal Eulen-Rundblick in DIN A4 format with its first issue bearing the number 39. Since 2007, one issue has been published every year.

Since the 1990s, almost all German owl experts have been members of the OWG. The group also has members in all neighbouring countries. There are individual members in other European countries, especially in Eastern Europe and the United States. 
About 20% of the members are other working groups or groups active in other conservation organisations, in particular the NABU, or public authorities. The number of members rose strongly in three phases. The first major increase in membership took place at the end of the 1970s, when the group's study area was extended to the entire Federal Republic of Germany, then the mid-1980s, when it was decided to expand the OWG's work to cover all species of owl, and then at the beginning of the 1990s, after German reunification.
