Adult common swifts staying longer in their nests
This year we observe an unusual phenomenon: after the young birds have left the nests, the parent pairs continue to stay there for weeks. They spend the night in their nests and also return to rest in them during the day, either individually or together. Do you make similar observations? Thank you for sharing them with our project "Picture my habitat": https://www.inaturalist.org/projects/picture-my-habitat
