We captured 32 new birds with 3 recaptures of 8 different species. Common Yellowthroats gave the Prairie Warblers a run for their money but fell short by 1 individuals for the most abundant species.
A hint of a black mask on the following Common Yellowthroat would usually indicate a hatch-year male, however closer inspection of the primary coverts (pp covs) revealed that this was an adult bird. Sometimes, adult females can take on male-like characteristics which is what occurred with this individual.

Red-eyed Vireos in the fall can be aged using eye color. Hatch-year birds will usually have brownish colored eyes while adults will have red eyes. When using eye color to age birds, I always confirm the age using secondary characteristics such as primary coverts shape/wear and outer tail (rectrices) shape.
