On a hot evening on 13th May 2024 on the island of Pag, Croatia I observed European Bee-eaters / Bienenfresser (Merops apiaster) and Eurasian Golden Orioles / Pirole (Oriolus oriolus) bathing together at the same time in a freshwater lagoon. Both species just dipped into the water on the fly, without landing on solid ground, but with slightly different approaches.
The photos below show two baths, one per line, of each species.
