Fall migration is an exciting time when birds flock together and pockets of activity can be found in food-rich habitats, such as those at the Marolt Open Space.  This parcel at the entrance to Aspen, with its historic mining and ranching features, is truly a birding hotspot.  Corners of fields, roadsides, old railroad trackways, stands of trees, a community garden, and several ponds together create a patchwork of habitats with diverse structures.  Today’s goal was to experience the bustling bird activity, and the Marolt Open Space more than delivered!  We birded along the dirt access road, in the community garden, along the open fields edged by the historic Midland trackway, the vicinity of the mining museum, and the Bergman Trail.  The top highlight of the trip was finding a blue-winged warbler foraging in low vegetation near the mining museum.  This is an eastern bird that is rare in Colorado and is listed on our local checklist under the Casual & Accidental heading.  The individual we observed was an adult male, and one of our birders took photos to document it.  We reflected on how to handle the excitement of a rare bird sighting:  take time to observe the bird while it is in view, memorizing as many of its field marks as possible; then get out a guide book or app to try to identify it.  We had the luxury of watching this bird for long enough to refer to the bird and the book at the same time.  Other highlights included a couple of female lazuli buntings, lark sparrows, Wilson’s warblers, western tanagers, yellow-rumped warblers, and many hummingbirds.  We enjoyed the abundance and diversity today, as well as the interesting mining history at this special site.  Join us on Thursday for another fall migration outing to the Gorge of the Roaring Fork!
