In the spring and early summer Ilmakkiaapa serves as the site for marsh birds to rest and nest. The common crane (Grus grus), whooper swan (Cygnus cygnus), bean goose (Anser fabalis) and many species of waders and water birds are then everyday guests of the mire. In Ilmakkiaapa a trekker may also get a chance to observe the tournaments of colourful ruff cocks (Philomachus pugnax). The time for waders does not last long, because many of them already begin their return journey before midsummer.

Note! (updated 6/15/2024)
The Ilmakkiaapa Duckboard Trail and bird-watching tower are closed due to very poor condition.
