Hubbard Fellowship Blog: Moo-Muration

A guest post by Eliza Perry, one of our Hubbard Fellows.  All photos are by Eliza.

Giant black clouds of birds have been erupting from cottonwoods everywhere I go the past few days.

As Anne recently shared, the cows have been taken away from our prairies for the winter and, somewhat surprisingly, their absence has really been felt around here. They were quiet company, but extremely entertaining at times, creeping toward me while I picked seeds until I lurched suddenly just to watch them bolt in the other direction. Before long, they’d crept back even closer to me, and we went on like this for many hours.

I have a quick story to share that I captured driving around on the last afternoon the cows were here, though the story is as much about birds as our dear
cows. I  saw a large flock of birds along a fenceline and pulled over to the side of the road to get a better look at them. The cow-bird interaction I witnessed was, or seemed to be, quite playful. And funny.

As if on a mischievious (or vengeful?) whim, the neighboring cows rushed at them.

So they lifted into the air in perfect unity, an effortless coordination that is said to resemble magnetism by statistical physicists studying similar behavior by European starlings.

Reluctant to give up their spot entirely, the flock settled down again close by.

That is, until a lone calf honest-to-goodness peeled away from the group and charged the fence, seemingly aiming right for the birds. Although I’m sure there was some other unseen reason for his behavior, I like to think this calf was putting on a show.

But that was apparently the last straw for the birds and they flew away toward the river.

I know starlings are invasive, outcompeting other species like bluebirds and woodpeckers, and cowbirds have a nesting parasitism habit, but the huge flocks these creatures form are a wondrous sight. I was picking rosinweed one morning when things were going any way but mine (I thought I broke two backpack sprayers in a span of two hours), and a gigantic murmuration passed right over me for about ten minutes, with no end in sight. Just a long, chirping highway. This event, along with my renewed awareness of the quiet, scenic solitude where I work, lifted my spirits and ended my morning funk.

The prairie has a knack for doing that to me – and I imagine it does so for everyone else reading this – so I think I’ll be all right without my cow companions.

Last month, our Platte River Prairies crew visited a South Dakota farm owned by our friends Gerry Steinauer and Grace Kostel.  Gerry showed us around the farm, including some prairies he and Grace have been trying to rehabilitate.  It was late afternoon, and scattered fluffy clouds and golden prairie grasses made for a beautiful backdrop for our hike.

Even though wildflower blooming season is over for the year, there is still plenty to see in autumn prairies.  Fluffy white seeds of goldenrods and asters fly into the sky as we walk by.  Migrating sparrows pop out of the grass but quickly drop back down, giving us just enough time to make wild guesses about species identification.  Harriers course back and forth above the tall grasses, making flight look effortless and wonderful.  In every patch of short sparse vegetation, grasshoppers gather to soak up as much sun as they can before their season ends with the first hard freeze.  That freeze is yet to come, but the chill in the morning air leaves no doubt that it’s just around the corner.
