Hirundo, the journal of the Estonian Ornithological Society, is issued twice a year. It publishes ornithological papers, comments and instructions, as well as EOS news. The journal is focused on original studies and discussion about Estonian birds, their numbers, biology and conservation.
In 2014 the society launched a new website and made all issues of Hirundo available for free online.
