Editor’s Note: Based on the observed rate of 8 monarchs per minute, we are using 480 monarchs per hour as the number sighted for this observation. However, this is solely so the migration rate can be compared with that of other observations; we don’t know whether the migration continued for a full hour, nor whether the rate was constant.
