Researchers find songbirds likely share info with other species during migration flights.
Researchers at the University of Illinois Urbana-Champaign found that migrating songbirds can communicate and potentially share information with other species during flight.
By analyzing over 18,300 hours of flight calls from 26 sites in Eastern North America, they discovered that birds of similar wing sizes were more likely to call out simultaneously, suggesting social interaction that could aid navigation.
The study highlights how interspecies communication might be crucial for songbirds' long migration journeys.
