While at Hammonasset Beach State Park a few weeks ago, Phil Rusch and I saw the sporadically continuing adult hybrid Tricolored x Little Blue Heron. The bird (one of two or three) was first seen as a juvenile during the summer/fall of 2011. A couple prior photos of mine can be found HERE.

Note the bill size and shape, yellow lores, pale thigh feathering, and white flecking on chin and throat (poor chin/throat view in this photo).
