Here is another set of directions I got from Khanh Tran (from Portland) as well. This is good if you don't have a DeLorme handy. I printed out both this and the one originally sent by Gene Hunn, and referred to them both.
Good luck to all you out there still wanting to see these birds.

I think we benefited greatly since there were just two of us out there, and we heard an unfamiliar song as soon as we got out of the car. It is high pitched, very high, and the notes are right on top of each other, but only 3-5 notes. And the pitch is exactly the same during its short song. Those who don't hear Cedar Waxwings and the like, will have a difficult time hearing it; if there is much else going on. Once you sort out the songs, he is easy to find. Even if you don't sort out the songs, he is still easy to find, just start scanning the tops of the trees.

Subject: Bay Breasted Warbler and Clay colored sparrow directions


Here are the directions to the BAY BREASTED WARBLER:

Take Exit 49 and then take Highway 504 out of Castle Rock (Probably on the
north end) and drive 18.2 miles. Turn LEFT onto FR 1900, and continue to
take the road that goes straight which has become FR 1901 not long after you
turn off 504. (1900 turns off quickly to the left.) Go 2.3 miles to a large
intersection. FR1901 will continue straight and goes down at that point. FR
1909 goes off to the left, and the bird was first seen about 1/10th of a
mile down 1909.

I saw the bird just past the intersection of 1909, but on either side of
1901...just a few yards past the white Weyerhauser sign, and the yellow gate
that can be closed across 1901.

PLEASE BEWARE OF INCOMING TRUCKS AND BE PREPARED TO BE DUSTED several
times!!

Directions to CLAY COLORED SPARROW:

The direction are described from I-5 northbound at Exit 88 (north of Centralia).

Take I-5 north to Exit 88 at the Tenino-Aberdeen Exit off of I-5. Continue
east on Old Hwy. 99, which is the main road you come to after exiting off of
I-5. Continue east on Old Hwy. 99 for about 5 miles to Melville Street, which
is somewhat hidden with conifer branches from the road if coming from the
west.

Travel .3 to .4 miles north on Melville Street as you pass a large Scott's
Broom thicket on your right. Take a right on a gravel road which has a
barbed fencing wire and scan to your right along the Scottish Broom.

Listen for the distinctive low buzzy trill-like song. The bird can be a bit
skittish.

It is expected the bird may stay at this location for some time since an
individual lingered here through the first portion of July during the early
1990's according to a local birder named Paul Hicks that surveys that area
on a regular basis. Also in the general vicinity are California Quail, House
Wren, Chipping Sparrow and a variety of other species.

Good luck and good birding,

Khanh Tran
