I went to Retzer Nature Center to check on the migrant bird activity. Just about all of the summer birds have officially cleared out and the birds of fall and winter have taken over. I started by walking the blue trail to the pond where Blue Jays were flying back and forth over the trail. The American Goldfinches that frequent the area have all transitioned to their drab colors. There were sparrows rustling in the tall grasses but none of them sat up high enough to actually make an identification.
I continued onto the green trail that goes past the tractor lane and into the forest. At the forests entrance there were three remaining Field Sparrows. As I entered the tree line I could see a lot of small birds flitting around. They turned out to all be Yellow-rumped Warblers. Further on the Green Trail I encountered a few American Robins and a Downy Woodpecker drumming in its usual location. From the woods I made my way to the top of the hill where the tall grasses of summer still remain. However, the bird activity had completely ceased. I did not find a single bird in the areas where the most activity happened earlier in the year.
From the hill I made my way down the tractor trail on the north side of the nature center. Here I encountered more field Sparrows and a group of Palm Warblers. The warblers were staying low in the shrubs but occasionally popped up and gave nice views. Also in the area was a single Ruby-crowned Kinglet moving quickly through the bushes. I moved south into the pines from the tractor lane and here I found the largest collection of birds on the whole nature center. At least 100 American Goldfinches were foraging on seeds from flowers as others were feasting on pine cones along with Black-capped Chickadees. Along with the Goldfinches and Chickadees were some Red-breasted Nuthatches. These birds are irruptive and can sometimes be found with much more regularity than others. I hadn’t seen any at Retzer for at least three years so it was nice to find a few of them again.
My last bird of the day was also found in the pines. It came in the form of the harbinger of winter: the Dark-eyed Junco. Juncos migrate south to Wisconsin each winter and they are a solid indication that cold weather is on its way.
In all, I tallied a decent amount of species in about an hour and fifteen minutes of birding.
