Unique notes in sarus crane duets help distinguish sexes for conservation

• A new study has discovered a novel social unit among sarus cranes, where these formerly monogamous birds now form trios to raise their chicks.
• Study authors note that these breeding trios were most observed in more degraded habitats.
• The highly territorial cranes may be forced to change their mating behaviours to increase offspring’s chances of survival as habitat loss in India is on the rise.
