Apart from its scientific name, the hoary redpoll has several synonyms that are used interchangeably to refer to the species. These synonyms include Acanthis Hornemanni, Linaria Hornemanni, and Leucosticte Hornemanni. The hoary redpoll is known for its distinctive red cap and small size, with males and females typically weighing less than one ounce.
