@alex @frumble Love it! After a little research I can say: it is an African Sub-Sahara bird (“Athoscopus”), but the picture is definitely from a Brazilian publication, probably a school or children’s book. This is what Wikipedia tells about the nests - they’re even more sophisticated: “Their pendulous and elaborately woven nests have false entrances above the true entrance, these in turn lead to a false chamber. The true nesting chamber is accessed by the parent opening a hidden flap, entering and then closing the flap shut again, the two sides sealing with sticky spider webs.”
