Transformation

"You don't make a photograph just with a camera. You bring to the act of photography all the pictures you have seen, the books you have read, the music you have heard, the people you have loved."

― Ansel Adams



It's less than a week until the Autumnal Equinox, but already the trees along the creek corridor are beginning to display a variety of brilliant fall colors. In some areas the transformation from green to golden has seemed rather abrupt. Though there are perhaps millions of songbirds yet to travel south across Wisconsin, I sense that peak warbler migration is behind us. Even so, I'm still finding Golden-winged, Black-and-white, Chestnut-sided, and many other wood warblers at the corridor. Soon, though, there will be more Palms and Yellow-rumps bringing up the rear of the warbler parade.

I feel I've been fortunate to find several Black-throated Blue Warblers this fall migration, with nearly an equal ratio of males to females. Typically, I encounter perhaps just one or two of this species each fall, but by plumage I can confidently state that there were three individual females and four different males. There are subtle differences in the size and shape of the white dash on the wing and feather wear for clues to determining uniqueness.

Young Common Yellowthroats are quite numerous around the confluence ponds west of Deming Way. I'm uncertain whether these are newly arrived migrants or dispersed birds that were raised this summer in the marsh adjacent to the ponds. There's really no way to know for certain, but it's fun to speculate and imagine. What a gorgeous little bird! It's my contention that the fall plumage of this male yellowthroat is more stunning than adults in breeding plumage.

For waterfowl the ponds held Mallards, Northern Shovelers, Wood Ducks, and Blue-winged Teal.

And Green Herons! Such adorable and gawky critters, they are.

Spring Green Preserve

On Saturday, and for the second year, I led a tiger beetle field trip at Spring Green Preserve for Natural Resources Foundation of Wisconsin and The Nature Conservancy. My mission was to have each participant see as many tiger beetle species as I could find. We were fortunate to see Big Sand, Festive, Oblique-lined, Punctured, Splendid, and Common Claybank. With the recent discovery of Northern Barrens Tiger Beetle at the preserve, six out of eleven is pretty good given the time of year. Virginia Metallic Tiger Beetle is primarily nocturnal, Ghost Tiger Beetle hasn't been seen there for several years, and Six-spotted are generally more plentiful during spring.

  1. Yesterday morning in the creek corridor, in addition to a few warblers, I also saw an immature Black Billed Cuckoo. He even sat right in front of me and looked at me for a few seconds. I had never seen an immature one before.
