The latest issue of The Connecticut Warbler is arriving now in COA members' mailboxes. Check out the historic records from the ARCC to find out the oldest accepted record in Connecticut. Hint: it's from 1840/1844 and although the species was once numerous, it is now possibly extinct. There has not been a reliable sighting since 1987 nor a confirmed sighting since 1963.
The CT Warbler only goes to current COA members, so be sure to keep your membership up to date or join us to learn more. (https://www.ctbirding.org/join-us/)
