Task: Question Answering
Input (English): passage: The distinction between ``doves'' and ``pigeons'' is not consistent. In modern everyday speech, as opposed to scientific usage or formal usage, ``dove'' frequently indicates a pigeon that is white or nearly white. However, some people use the terms ``dove'' and ``pigeon'' interchangeably. In contrast, in scientific and ornithological practice, ``dove'' tends to be used for smaller species and ``pigeon'' for larger ones, but this is in no way consistently applied. Historically, the common names for these birds involve a great deal of variation between the terms. The species most commonly referred to as ``pigeon'' is the species known by scientists as the rock dove, one subspecies of which, the domestic pigeon, is common in many cities as the feral pigeon.
 question: is there such a thing as a white dove?
Output (English): Yes
