Your coyote story prompted me to report my sighting of a mountian lion back on August 21st, 2011.  I reported the sighting as soon as I confirmed what I had seen online by searching mountain lion images.  First, I called the CT DEEP to report it, and was told I saw a coyote.  I know what coyotes look like.  It was a mountain lion.  RIght away, I also sent CT DEEP an email.

This is the email I sent 8/21/2011 to White Memorial Conservation Center:
Dear To Whom it Concerns,

I was at your long boardwalk, the end of it where there's a bridge (not the bridge near the golf course, but the second, longer bridge) on August 21, about 7:30 am, and spotted an animal on the bridge.  I moved closer, thinking I was going to see a rabbit, and there was a full sized, all-over tawny-gold mountain lion.  I stood still, it turned its head and spotted me, then it moved away down the boardwalk, nice and unconcerned.  I didn't realize it was a mountain lion, until I went home and checked my Audubon Society Field Guide to New England, and saw I had not seen a bobcat.  I went online, and checked mountain lion images.  What I saw looked exactly like this:  not a bobcat, nor a coyote--I had an unimpeded view, in daylight, and this is what I saw.  The lion was the height of my lab-Rottweiler mixed, adult dog, long and lean.  I waited until another group of walkers came over the bridge behind me, told them what I saw, and we walked out of the park together.  I am glad I mistook it for a bob-cat then, or I would have been afraid to go to my car.  I've reported this on the phone to the DEP.  I think you should post something about this sighting at your park.  Thank you,  (my name and address blocked out here)

This is their response to my email:

(My name removed by me),
Thank you for forwarding your observation to us.  Since mountain lion (Puma concolor) is considered an extinct species in Connecticut, we require that physical evidence of mountain lion observations is examined before we can attribute the observation to our property.  We define physical evidence as tangible, measurable, and verifiable observations that can be corroborated by multiple experts who are accredited.  Examples of physical evidence include and are not limited to whole specimens, scat, and tracks.  We will take into consideration photographic evidence; as long as they record the locality and ability to scale the size of the animal. 
Thank you for reporting this information to CT DEEP, since they are the central agency that coordinates the monitoring efforts of mountain lion observations in Connecticut. 
Best Regards,
James Fischer
Research Director

Later I learned my story was copied without my knowledge from a web posting I made and run in the Litchfield County Times news.

In Litchfield County, where I reside, we had a bear in our yard (got pictures of that), we have coyotes running about at night, see hawks, turkeys, foxes, deer, and last week a moose was spotted not far off from our area.  The suburbs have their share of predators and prey.
