House Finches and Purple Finches can be difficult to tell apart. For this survey, it is important that participants be able to note the difference. The disease affects mostly House Finches, and recorded Purple Finch infections are somewhat uncommon. The following are pictures intended to help participants distinguish the two finches, along with comments on major field marks.
