According to the list serves, there is a Chestnut-sided Warbler in the northwest side of Pantoja Park in San Diego. This little beauty is a common winter bird in the eastern half of the US and Canada, but is rarely seen on the west coast. If you want to add this warbler to your list, we suggest you get out to Pantoja Park and maybe even pick some litter while you're there on this National Day of Service.
