Sandhill Cranes migration

The Sandhill Cranes overhead were so loud and so many I could hear the in my house with the doors and windows closed. Ellie

Wow I think they are telling you spring is just around the corner! The loud resonant gu-rrroo, gu-rrroo gu-rrroo calls of a flock of sandhill cranes flying high in the sky can be heard a mile or more away. Thank you for taking the time to share your observation with me. You’ve inspired me to make them the bird of the week.

Sandhill Cranes are very social birds that mate for life. On migration, their flocks number into the hundreds and are composed of mated pairs and close family members. While migrating, they communicate constantly with one another. Interestingly, males and females often sing duets as they fly.

It is always a special treat to find a flock of sandhill cranes on the ground. Look for them during migration late or early in the day in large fields or open, shallow wetlands. Only then can you appreciate their size and beauty. Sandhills are a tall, long legged, long necked gray bird with a bright red crown. From wingtip to wingtip their outstretched wings can measure up to 7 feet.

They feed on frogs, fish, and insects, but also take much plant food such as seeds, fruits, and aquatic vegetation. They are often seen feeding in corn and upland grain fields. In Michigan, sandhills nest in solitary nests on the ground near or over shallow water in marshes and bogs. They nest by heaping plant debris into a low mound. Two eggs are laid; the young follow the parents soon after hatching, fly in about 70 days, and stay with the parents for nearly a year.

Their numbers were much reduced by habitat loss and shooting in the early part of this century but have grown in recent decades. A two year survey funded by the Nongame Wildlife Fund confirmed 805 breeding pair statewide. Most breeding pairs in the Lower Peninsula were found in a six county area near Jackson and Ann Arbor. Highest concentrations in the Upper Peninsula occurred in the eastern counties.
