I rarely see Black Tern in/near breeding plumage in CT, so this was a treat for me. The second half of June is probably the slowest two-week period you'll see for bird migration in CT during the warmer months, but it is still a decent time for wandering terns. Scarce species tend to be drawn to flocks of Common Terns, but flocks of those are usually quite difficult to observe from land at this time of year in Connecticut. There are precious few breeding colonies in CT, and they tend to occur on offshore islands. Access to a boat is key to seeing flocks of Common Terns in June. That will change sometime in July, when post-breeding COTE begin to spread out and stage in flocks near beaches and river mouths.
