My Goshawk over the years has show seasonality, predictably present during
the spring breeding season and a time when I need to keep an eye on my chickens.
(Nine healthy meals over the last 4 years.) During the winter, these
birds do not appear to be present and I do not clearly understand where they
go. Migration is relative in this species and most likely to range rather
far as Clark commented below. They are clearly dedicated to our intact
forest in Town Hill for nesting and have been present along with Broad-winged
Hawk since forest regrowth in our once farmed land. (1890’s).... The
Broad-winged often alert me to the Goshawk.....My guess is that our island
Goshawks move inland and roam the coastal edge searching for Grouse, Jays,Am.
Robin and perhaps my company Logo, the Northern Flicker.

The Flickers down south are molting tail feathers which makes any bird
vulnerable to a stealth-full Goshawk or Coopers.
