On Cape Cod there is not a lot of high ground, except for in the sand dunes and a few other spots. Most of the Cape is low ground like old bogs, tidal creeks, marshes, swamps and ponds with some small rises in between.
Many of these areas will have lower areas of thicker cover which coyotes will use as travel corridors. When answering the call, the coyotes will use these low (or lower) paths for their approach.
