Kill in that Old Dutch country means stream or creek. We hiked, for example, for many miles up Beaver Kill, a stream that flows into the East Branch of the Delaware River. Thus Catskill means cat's creek. Our nighttime serenader was simply introducing us to its domain. More likely it sought to attract a mate.
Bobcats usually breed in springtime, but they are known to pair up at any time of year.
Although they are felines like house cats, bobcats are twice their size. They have distinctive facial ruffs and barring on their bobbed tails. Not just found in the Catskills, they are widely distributed across the United States, southern Canada and Mexico. However, much of the Niagara Frontier is in an area where they are rare that extends south of the Great Lakes all the way to eastern South Dakota. Five of us were hiking the 63 mile Catskill section of the Finger Lakes Trail.
