I spent several hours hiking about 8.75 kilometers of Connecticut Audubon Society's 155-acre Roy and Margot Larsen Wildlife Sanctuary adjacent to our Center at Fairfield yesterday morning and afternoon, finding and recording all of the life that I could along the way. I covered nearly the entire sanctuary, not passing through the same area more than once. I tallied 30 (or 31) species of birds along with spotting or finding signs of 10 mammal species. I only saw evidence of that 31st species as I found this owl pellet near the end of my hike.
This photo was taken after I had picked it up and pulled it apart a bit. It was approximately 1.5 inches long and quite fresh and compact initially. Take a look at all the tiny bones in there among a lot of fur to see if you can identify specific parts. It looks like you could piece together a small mouse. From the size and composition of the pellet and its prey, I believe it came from an Eastern Screech Owl. That would also fit in with the habitat and location that it was found in - wet woodlands.
Some of the common bird species were seen in high numbers. In particular, Tufted Titmice seemed to be everywhere as I encountered a few groups of 6, 8, or even more individuals foraging together, totaling 36. There was also a fair number of White-breasted Nuthatch for the area at 14, and quite a few Dark-eyed Junco adding up to 72. I know many people have wondered where their feeder friends are in this warm winter, and the answer may be no further than your own local forest patch.
