The male blue-throated hillstar has a blue throat and the male black-breasted hillstar has almost entirely black underparts. Compared to the Andean hillstar, the male green-headed hillstar has a brighter green head and a black (not brown) line to the central underparts.[1] The binomial name commemorates Polish ornithologist Jan Sztolcman (Jean Stanislaus Stolzmann).
