Birds Communicate Reproductive Success In Song
CORVALLIS, Ore. – Some migratory songbirds figure out the best place to live by eavesdropping on the singing of others that successfully have had baby birds – a communication and behavioral trait so strong that researchers playing recorded songs induced them to nest in places they otherwise would have avoided.
This suggests that songbirds have more complex communication abilities than had previously been understood, researchers say, and that these “social cues” can be as or more important than the physical environment of a site.
