American Redstart, 8 & 11 December 2019

Taken at the Hagerstown City Park in Maryland. Quite surprised to find this gem of a bird, who should have migrated south for the winter back in September. A friend told me, "Might be the latest MD record if eBird is correct! I was seeing December 6 in Baltimore County and that record was from 1950!" I went back on December 11th, a sunny day, and found the same Redstart. I believe this is a female.
