We are in the midst of a Pine Siskin irruption which, according to Audubon, is the greatest irruption of Pine Siskins on record. I know they are rarely seen in the upstate of South Carolina, but I’ve had anywhere from 50 to 70 in my backyard sanctuary every day since October 17th. I’m posting this, first, as a heads-up to be on the lookout for them as I’ve talked to other birders who mistook them as “just another House Finch” until they realized what was going on and began to observe more intently. Secondly, I’m wondering if there is anything being done in iNaturalist to monitor and track this momentous event?
