Brass keys with red enamel hummingbird charm

I lost my standard-sized brass house keys yesterday around 3pm near Front Street by the Riverwalk in Wilmington. There are two keys on a tarnished brass ring, one Yale house key and one Schlage deadbolt, with a red enamel hummingbird charm that's a bit scratched. They're attached to a frayed black braided cord that used to be part of a lanyard. The keys have sentimental value for me--they unlock my grandmother's condo and my own apartment--and I'd really appreciate getting them back if found.
