Morning Birding Species List | September 5, 2017

Location: Hallam Lake Nature Preserve
Hallam Lake Nature Preserve was teeming with bird activity this morning, especially on the steep hillsides above the lake to the south, where fruiting shrubs are a major source of food at this time in the season. Robins in flocks of juveniles and adults were eating chokecherries and very active in general. Cedar Waxwings were also gorging on all the wild fruit. We had opportunities to study adult and juvenile plumages in Evening Grosbeaks as they bathed by the little footbridge near the visitor center, and in waxwings as they foraged. Song Sparrows and Lincoln’s Sparrows were feeding in shrubs, giving us an excellent chance to compare their field marks side by side. A juvenile Osprey was perched in a tree at the far end of the main lake through the morning. We were able to clearly see its ‘chevron’ pattern on wings and back, as well as its pale iris color, both of which are diagnostic field marks for young Ospreys. The birding at this time during fall migration is fantastic! Join us next week at Hallam Lake for more exciting observations of resident and migratory birds!
