A motherlode of Lincoln's Sparrows

The inaugural Headlands Birding Festival took place last weekend, based at Headlands Dunes State Park. There were a number of breakout speakers on Saturday afternoon, and keynotes Friday and Saturday night. Greg Miller of The Big Year fame was on Saturday, and your narrator spoke about the Great Lakes and their importance on Friday. From what I could tell, there were several hundred attendees, and more people than that wandered through the vendors and exhibitors on Saturday. It was a great time, and I believe this event will only grow. The Lake Erie lakefront in northeastern Ohio is incredibly important for fall migrants, and this makes for great birding as we shall see.

Mentor Marsh was the location of our field trip on Saturday morning, led by Becky Donaldson of the Cleveland Museum of Natural History and me. We met our group of about 25 people at 7:30 am and hiked this elevated dike through the marsh. While the trip was scheduled to end at 9:30, many of us stayed until about 11 am. The birding was magnificent, and the glut of Lincoln's Sparrows was right along this dike. We estimated 15 Lincoln's Sparrows on our trip, but I knew far more were present. Note the pale lime-green zone off the left side of the dike, right before the trees. That's rice cut grass (Leersia oryzoides) forming a large drift. Its fruit was ripe and seemed to attract lots of sparrows.

While field trips are fun, a great way to showcase natural history, and several of our participants saw new "life" birds, large groups are definitely not the effective way to stalk shy, skittish sparrows, especially insofar as photography goes. In fact, I didn't even bring my camera on the field trip. Probably should have but when one is leading, it's rude to become self-absorbed and get into shooting pics and ignoring the group. I don't even want the temptation, although I would have regretted that decision had a Steller's Sea Eagle or something crazy flown by. Anyway, I got permission to come back to this spot the following morning, at the crack of dawn, camera in tow.

This is the view to the north from that dike. The bulk of the 1,000-acre marsh stretches in that direction. I wonder how many Lincoln's Sparrows were up that way. Probably hundreds. I just sampled a tiny portion of the vast wetland - one-half mile in, and the same one-half mile out.

Here's a nice mugshot of a Lincoln's Sparrow (Melospiza lincolnii). It is in the same genus as the Song Sparrow (M. melodia) and Swamp Sparrow (M. georgiana), and is superficially similar to both, especially the Song Sparrow. But once one is familiar with the comparatively dainty and compact Lincoln's Sparrow, with its neatly striped dapper plumage, subtle gray and buff tones, and generally much more animated behavior, they are quite easy to identify.

As soon as I entered the trail, I began seeing Lincoln's Sparrows. At times I could see a dozen at once. In all, I tallied (and eBirded) 75 but am sure that's just a snippet of the true number that was present in the marsh.

Here's a Lincoln's Sparrow in a buttonbush plant (Cephalanthus occidentalis). The sparrows seemed smitten with the fruit - brownish balls on bottom left corner - and this particular shrub often had multiple sparrows simultaneously. I failed to get the money shot of a sparrow with buttonbush seeds in bill, although I saw it happen numerous times.

Many Lincoln's Sparrows were further out in the marsh, like this one teed up in some cattails. They were generally in proximity to the beds of rice cut grass, which is why I suspect they were harvesting its abundant ripe fruit.

In all, I photographed probably 6-8 different individuals. This one popped out very briefly on a branch near the ground. When skulking in dense vegetation, especially on the ground, which is how Lincoln's Sparrows often behave, it can be tough to get even a good enough look to positively identify them.

Here's a front shot showing the fine streaking and subtle buff wash which contrasts with the grayish head. The dapper little sparrows are sometimes said to resemble "well-dressed" Song Sparrows (at least by me).

A Lincoln's Sparrow, on point, showing a classic alert posture with raised crown feathers. This one was part of a group foraging in a small black locust (Robinia pseudoacacia) thicket.

A three-fer in this shot: Lincoln's Sparrow (bottom right), Common Yellowthroat to its right (your left), and a Song Sparrow above. The closely related Song Sparrow is quite different even if superficially similar. It is "messier" in appearance - never the neatly dapper plumage of the Lincoln's, nor does it present the obvious gray and buff tones that are often so obvious with Lincoln's. Song Sparrow gestalt is different as well. It is a larger bulkier bird. The average Song Sparrow weighs about 23 grams, while a Lincoln's weighs about 17 grams. That's about 25% lighter which translates to a much different field impression.

I noticed that several Lincoln's Sparrows were drawn to the few and scattered Staghorn Sumac (Rhus typhina) treelets. This was early on my foray, and as you can see in this photo, the large flat sumac leaves were still copiously beaded with dew.

This is the same bird as above, shortly after I made the preceding shot. We've probably all heard the trendy sillyism "forest bathing" put forth by hipsters trying to get closer to nature or whatever. Well, this is real forest bathing. The Lincoln's Sparrows were bathing in dew: pushing and rubbing into the wet sumac leaves, then vigorously shaking and preening. It was really cool to watch this, and it did make me feel closer to nature.

It wasn't just Lincoln's Sparrows on my 2 hour and 15-minute immersion into the marsh. In all, I detected about 50 species of birds, including seven other sparrow species. The latter tally included a Clay-colored Sparrow, rather a rarity in this neck of the woods. Several Nashville Warblers and a Palm Warbler were working the goldenrods, and several Bobolinks passed overhead giving their melodic "pink" calls. Raucous families of Red-headed Woodpeckers made aerial sorties in between harvesting acorns in the nearby woods. At one point, I saw the whirlwind appearance of an accipiter far ahead, undoubtedly trying to whack the sparrows and warblers that I was admiring. It was just a split-second look, but now I was on point, waiting for it to reappear. A minute later, a female Sharp-shinned Hawk - a songbird's worst nightmare - shot from the shrubs and within ten feet of my head, surprising both of us. The snappy little raptor winged down the dike, then landed on the ground staring around ferociously. As nearly always happens, the songbirds fell silent and waited for the threat to disappear.

I'll try to post some other imagery from this trip later.
