Birger moved to Paris in 1877, and spent the summer of 1878 in Barbizon with Carl Larsson and Carl Skånberg. He debuted at the Paris Salon the following year with Rue Gabrielle (1879, now in the Gothenburg Museum of Art). He submitted his painting Toaletten (English: The Toilet), which depicts a lady in front of the toilet mirror, to the Paris Salon in 1880. From 1881 to 1882, Birger visited Spain and Northern Africa. His largest painting from Spain was La feria ("The Feast Day", 1882, Gothenburg Museum of Art), which depicts a breakfast in Granada.
