For Love of Sandhill Cranes

We know from fossilized records that the Sandhill Cranes are one of oldest birds in the world, and have been in their present form for 10, 30, or 60 million years (depending on the source). They have apparently maintained a family and community structure that allows them to live together peacefully and migrate by the thousands along Nebraska’s central flyway twice a year.
Sandhill Cranes mate for life, and in the spring the adults engage in a complex “dance” with one another. During mating, pairs vocalize in a behavior known as "unison calling." They throw their heads back and unleash a passionate duet—an extended litany of coordinated song. Cranes also dance, run, leap high in the air and otherwise cavort around—not only during mating, but all year long (Even young birds dance and throw sticks and grasses into the air while jumping around enthusiastically).

In their northern habitat, the female lays two eggs a year in thick protected areas at the edge of reed filled marshes. Before nesting these birds “paint” their gray feathers with dull brown reeds and mud to reduce the possibility of being seen by a predator. Born a couple of days a part, the second chick rarely survives. The remaing fuzzy youngster that might make it through the first year stays with its parents for about three years before reaching sexual maturity and striking out on its own, but even then the adult stays within the parameters of its extended family, and it is these families that comprise the flocks of cranes that we see flying together. During migration, a multitude of these families travel together by the hundreds or thousands. There are no leaders and often it is possible to observe what looks like an unorganized random flock (but isn’t) or diagonal thread made up of cranes flying (up to thousands of feet) above the ground.
 
In every watery roosting place there are a few cranes that remain awake all night alerting their relatives to would be predators, and in fact I have been awakened during the night by crane warning cries that sound quite frantic and are higher pitched than normal. I think it’s significant that these very ancient birds have survived so long in their present form. Could it be because they understand the value of living in community, perhaps acting as models for humans who, for the most part, seem to have forgotten what genuine community might consist of? 
 
Most recently these birds have been a presence in my life since last November when they first arrived, I believed for a brief stopover, before moving south to places like the Bosque del Apache to spend the winter.
 
When I first came to New Mexico almost three years ago I was astonished and bewildered by their haunting collective cries even when I couldn’t see them which was most of the time during the same fall month…
 
This year the cranes not only stopped by but many decided to spend the winter here much to my great joy, perhaps a result of Climate Change which is shifting their migration patterns and created conditions like the extreme drought that dramatically lowered the level of Red Willow River over this last year.
 
My hypothesis is that the resulting shallow riffles (one of which just happens to be below my house) provided many cranes with the safety they needed to roost there all winter long. For three precious months I listened with awe and wonder to pre-dawn crane murmuring and on sunny mornings watched huge flocks of cranes take to the air with their haunting br-rilling cries. Every night I stood outside to listen to that same contented collective murmuring just before dark as the cranes settled in for the night.
 
When they are all talking to one another during the day (cranes need to be in constant contact with each other/family members) it is hard to distinguish one voice from another because listening to the whole is a symphonic masterpiece. But this winter I slowly learned to identity various cries by listening carefully to smaller groups as they took to the sky. The highest pitched voices belong to the youngsters, the lowest and most full-bodied calls come from the males, and the females speak in tongues from the middle.
 
Sandhill Cranes are omnivores and feed in wet meadows or in shallow marshes where plants grow out of the water during the warmer seasons. They prefer a diet of seeds and cultivated grains but also include berries, tubers, crayfish, frogs, small mammals, worms and insects. In the field next to me I think they fed on wild sunflower seeds and native grasses.
 
As previously mentioned Climate Change is shifting migration patterns. Some groups are now spending their entire lives in one place like Florida (these are endangered), others are no longer migrating further south than Tennessee, although they also fly north in the spring. It is unusual to have Cranes living in Northern New Mexico, although I understand from local fishermen that a few have occasionally remained here throughout the winter. I recently learned that Sandhill Cranes have even been observed in parts of Maine.
 
Their normal migration routes take them from Mexico as far northwest as (eastern) Siberia, into the Canadian Shield and Alaska to breed with one major stopover in Nebraska at the Platte River where 600,000 cranes meet to rest themselves for a month before making the last leg of their arduous and dangerous seasonal journey (another group that settles further northeast makes a stop in Mississippi). In the fall all northern populations will make the trip south for the winter because of inclement weather and lack of food, stopping again to rest and feed at the same places.

​New Mexico and Texas have the dubious distinction of being the first states to legalize Crane slaughter and now every state along their central flyway except Nebraska engages in spring and fall hunting. We can thank the state Fish and Wildlife organizations for “managing” the crane population by issuing licenses to kill these magnificent birds to bring in even more money when these organizations are already extremely well supported financially by the NRA and our taxpayer dollars. A Caveat to those that don’t know: All State Fish and Wildlife agencies, that purport to support wildlife have a deadly hidden agenda: to kill birds and animals at their discretion.
 
Although at present these birds appear to be maintaining a stable population the low survival rate of even one chick a year alerts us to the fact that uncertain survival rates and delayed reproduction factor into the difficulties inherent in crane conservation, and to that we must now add Climate Change – the ultimate unknown. It is prudent to recall that by conservative estimates we have already lost 50 percent of our non – human species.
 
When I first began to hear the Cranes I never imagined that I would start to see them or watch them make gracious descents into a neighboring field at all times of the day, every day for months. Watching them cup their six - foot wings, drop their long legs and spread their tails as they parachuted to the ground is a gift that I have never taken for granted. A solitary musical rolling rill, a haunting cry that raises the hair on my arms is a sound that now lives on in my mind and body.
 
Spring migration has begun and the largest aggregations of cranes are moving north. Some days the bowl of blue sky feels too empty, but some small flocks are still visible especially during the early morning and again at dusk. I noted the sudden loss of the largest flocks just before this last full moon and wondered if these birds also migrated at night. Further research confirmed that Sandhill Cranes sometimes do migrate after dark during the week before and after full moons.
 
A few days ago the Core of Engineers opened the dam raising the river - the protected riffles below my house disappeared, so during this last week in February I am without the morning joy of listening to nearby pre-dawn murmuring, but can still see and hear some Cranes flying by.  According to my friend Barbara R. some flocks are still at the Bosque del Apache, so hopefully we will be hearing their haunting cries as these last Cranes fly northward. It isn’t until April that all Sandhills reach the Platte River …
 
Pueblo people say that humans were once Cranes who lived in the clouds… they came to earth and danced for joy in the rain… Cranes also watched over ceremonies and remain a part of some Indigenous rituals today.  Additionally, Sandhills act as Guardians for the People easing transitions from life to death and beyond….
 
Cranes are Elders in every sense of the word, ancient relatives and they continue on, some adapting, others following scripts or patterns that stretch back to antiquity. The way they live, migrating out of seasonal necessity, returning to home - places, celebrating through community and song in life and death is a way of being that embodies flowing like a river… And for that, their magnificent beauty and inherent wisdom, I thank them.
