This species has been recorded as a North American bird on account of its alleged 
accidental occurrence at Cambridge, Massachusetts; but the circumstances, as related, 
strongly indicate substitution (perhaps accidental), by the taxidermist, of a trade 
skin of this species for a specimen of the common Archilochus colubris.
