Nature's Vitamins and New Trees

Gizzard shad -- a welcomed and well-timed morsel in the marsh

Yesterday, I took about twenty images of the individual photographed above before I got the lighting right. (It didn't help that I was using my cell phone and a crude kitchen light in the bunkhouse.) I went to the trouble of getting the shot of this modest (and smelly) "baitfish" because the species always reminds me of this time of year. And their presence in the marsh lead to a few interesting sights as my day progressed yesterday.

One of ten large native trees planted
around the bunkhouse this past weekend
(yellow poplar or tulip tree)
Gizzard shad spawn in huge numbers mainly in larger lakes, reservoirs, and rivers throughout Ohio (and in many states east of the Rockies) in the spring. While adults can exceed 20" in length -- and 3+ pounds -- they are perhaps most important in the food web as they grow to the size pictured above . . . a modest 3-4 inches.

While survival rates are low during early development (largely because they are being eaten along the way), millions -- perhaps billions -- survive their first summer in Lake Erie and its tributaries. As with midges and warblers, nature is setting the table with gizzard shad. Just as temperatures drop in mid- to late autumn, temperature sensitive yearling shad pulse into shallow water in huge numbers. Their fat-rich bodies serve as mobile and essential energy boots not just for other fish (stocking up for a long, tough winter) but for fish-eating birds prepping for or working through a strenuous seasonal migration.

I watched eight hooded mergansers and literally thousands of terns pluck unsuspecting shad from the marsh throughout my morning yesterday. I focused on the ducks carefully for the better part of a half hour, and based on my observation, they were batting a pretty high average. An individual duck would come up with a fish about 50% of the time. Good for the ducks; not so good for the shad.

As a sidebar, I had to smile as I drove the kids to school this morning. Our path follows the banks of the Maumee River, and when we got to the flat, exposed rocks and rapids along Side Cut Metropark, the kids couldn't believe the number of gulls feasting up tight along the shore. There had to be several thousand packed tightly together both low in the air and on the water. We have seined shad together this time of year at that exact location, so everyone knew what was going on. We pulled over briefly to take in the spectacle. Happy gulls, happy kids, happy dad. The seasons march on.

I'll share more of the backstory as to how these awesome trees got planted in a future post, but for now, I just
wanted to point out how much of an improvement they make as you approach from our south entrance
These three oaks are already pushing 15' tall; it will be tons of fun to see them grow to be 75'+!
-- we're excited for the shade they will eventually bring (not to mention the acorns)
