CObirders:
I’m going to go out on a limb and identify this hawk as a juvenile American
Goshawk. It is difficult to distinguish this species from a juvenile
Cooper’s Hawk, but I think that my pictures enable that to be done.
This bird has field marks characteristic of a juvenile Am. Goshawk: (1)
uneven tail bands, (2) a white supercilium and black auricular patch, (3)
heavy dark brown streaking on breast and belly, (4) speckled pattern on
upper back, and (5) a bulkiness that is apparent when taking off.
Experts may say that sitting on a fence is more characteristic of a
Cooper’s Hawk, but I have seen an Am. Goshawk sit on a fence post out in
the open while living in the mountains.
A few weeks ago, I saw an adult goshawk in my catalpa tree, but I was
unable to get a picture of it. I suspect that the two birds are related.
Having hawks around our feeders is a mixed blessing! Most days I simply
have no birds because there is a hawk (usually a Cooper’s, but I have also
had Red-tailed Hawks).
