Sandhill Cranes at Horicon Marsh NWR, WI: Memorial Day, 2017




Sandhill Cranes




This pair has one colt (chick)




Yesterday the pair had two so one was lost to a predator over night.






The Sandhill's call is a loud, rolling trumpeting sound whose unique tone is a product of anatomy: these cranes have a long trachea that coils into the sternum and helps the sound develop a lower pitch and harmonics that adds richness.



Juveniles stick close by their parents for 9-10 months after hatching.






These cranes are known for their dancing skills.  Courting cranes stretch their wings, pump their heads, bow, and leap into the air in a graceful and energetic dance















When the roving trio got closer to the marsh the territorial male Red-winged Blackbirds started dive-bombing the adults, even landing on their backs and pecking them.




Sandhill Crane chicks can leave the nest within 8 hours of hatching and are even capable of swimming.



The adults were catching small fish to feed to Junior







Although some start breeding at the age of 2, Sandhills may reach the age of 7 before breeding.  They do mate for life - which can mean two decades or more - and stay with their mates year-round.
