Photo of the Week – September 19, 2013

I was a little surprised last week to find a fledgling meadowlark in the Platte River Prairies.  The bird was young enough that it still couldn’t do much more than flutter clumsily away from me as I first approached it.  The bird must have come out of a very late nest (probably the 3rd or 4th nesting attempt by its parents?)  Multiple nest attempts aren’t unusual for grassland birds – many nests fail because of predators or other reasons – but I can’t remember ever seeing a bird so young this late in the season.

This young meadowlark peered through the grass at me as I crept close enough to photograph it.  Platte River Prairies, Nebraska.

While this particular meadowlark was unusually young for this time of year, it’s common for young-of-the-year birds of many species to hang around prairies longer than their parents, many of whom migrate south soon after their offspring leave the nest.  Because they are not expert fliers and inexperienced with life’s challenges, those newly independent birds are vulnerable to everything from predators to haying equipment.  In some species, young birds appear to take advantage of the adults’ absence by scouting for their own potential future nesting locations – a strategy that might help save them time when they return from migration next year.  However, just knowing where you want to set up a territory doesn’t mean you can fight off a more experienced male who has the same idea!

Photo of the Week – August 15, 2013

I took my two sons up to the Niobrara Valley Preserve earlier this week for one last outing before school started.  It was fun to see the Preserve through their eyes.  While I was looking at impacts from last year’s fire and grazing and noting ecological interactions between sunflowers and insects, the boys were chasing toads and just having fun bouncing along through the sandhills.

The big selling point to get the kids to tag along was the promise of seeing bison.  After driving around the 10,000 acre pasture for more than two hours without a bison sighting, I was getting a little nervous about keeping that promise.  Just as I was about to give up, the radio crackled and Richard (our bison manager) called to say he’d spotted bison at the opposite end of the pasture while he was working on something else.  About half an hour later, we found them and the trip was officially a success.

Here are a few photos from the two days:

It was a relief when we finally popped over a hill and saw bison spread out below us.

The bison seemed sleek and healthy, clearly thriving in the abundant regrowth after last year’s wildfire.
