Vertebrate Miscellany

by Carl Strang

Today, a few vertebrate notes from Mayslake Forest Preserve last week. The redtail youngster still is around.

Though it mainly sits perched in trees or, in this case, on a light fixture, calling frequently, occasionally it changes locations.

One skillful fisherman pulled a nice largemouth from May’s Lake despite the heat.

The bass looked to be 2 pounds or so. The man was fishing early in the morning.

Another example of fishing success was provided by a great blue heron in the stream corridor marsh.

The question is, what was the prey?

The bird was way over on the other side of the marsh. The prey was floppy when the heron shook it, shiny and smooth from the reflected light, and somewhat elongate and irregular in shape at times as the bird shifted its catch. My impression, supported by the dark color (though it was somewhat backlit) is that the prey was a bullhead, which is news because I didn’t think there were any fish in that marsh. The other possibility is a frog, which might better fit certain irregularities in its shape. I’m left with some uncertainty on this one.

    At least you can safely rule out a Big Mac!
