It may disperse or emigrate in summer. It arrived at Thornton Creek
in 1969 and has had a deleterious effect on several cavity-nesting birds
(see section 4-F-3).
There used to be 10-50 nesting pairs here, but they have decreased
by 1988 to only 1-2 pairs; in 1989, no nesting pairs were noted. This
decrease may have resulted because Faxon has sometimes destroyed starling
nests and shot adult starlings. Nevertheless, their Daily Frequencies in
summer remain high.

In some years, they were present through the summer. In other years,
however, they appeared to be only spring or fall migrants, perhaps because
they were more inconspicuous while they nested in June.
It seemed subordinate to the Warbling Vireo (see sections 4-F-5 and
6-B-145).
On 9 July 1974, a nest with three eggs and one newly hatched young
was found.
They were sometimes present during fall migration "waves" (see
section 5-G-3).
They were recorded more often after 1976. They may have been
uncommon earlier because Faxon was still becoming familiar with them, not
because they may have been rare. They also may be cyclic because they
were not as frequent in 1979 or 1990 as in other years.

Hutton's Vireos were noted mainly on the basis of their call. Since
they don't call much in winter, they may have been more common in winter
than the 1973-1983 records indicate. In particular, the lack of December
records in 1973-81 may be because they were overlooked.

On the days following their arrival each year, they were usually
present. For example, the previous tabulation indicates that they were
found an average of 65% of the days in the 10 day period after their
arrival.
The probability that they would be present near their average arrival

(Table 5.2).
Prior to their departure, they were often not present. For instance,
they were found an average of 41% of the days in the 10 days preceding

On the days following their arrival each year, they were usually

found on an average of 77% of the days in the 10 day period after their
arrival.
The probability that they would be present near their average arrival
date each year is low because their average daily presence was only 40%
during the five day period before and after their average arrival date
(Table 5.2). However, they were usually found each year on their average
arrival date and 4-5 days thereafter (Table 5.2).
Prior to their departure, they were often not present. For instance,
they were found on an average of 17% of the days in the 10 days preceding
their departure.
In 1979, 1982, and 1987, they were absent for 1-2 months in July or
August before reappearing. This suggests that, at least sometimes, there
may be a fall migration after the local birds leave.
They could sometimes be present during fall migration "waves"
(section 5-G-3).

They have generally only been migrants here, although there was one
record of a nest with 10 eggs (which may have included some cowbird eggs)
in willows in about 1970.
The reason why they don't remain around Thornton Creek may be because
there is a lack of suitable riparian habitat. There is some willow and
assorted brush along Thornton Creek which runs through an open meadow, but
apparently these warblers do not find this sufficient.
Occasionally, birds will stay for several weeks along the creek,
singing and showing territorial behavior, but they almost always disappear
before enough time has elapsed for breeding to have taken place.

UNCONFIRMED.--In 1978, an immature was sighted that had greenish
upperparts, white underparts, and a white eye-ring.
On 10 July 1990, a singing bird in breeding plumage was discovered.
Its crown was bright lemon-yellow. Its lores were black, with the black
extending from the lores back over the eye to the nape; this black streak
also joined another black streak that extended downward from the lores
along a white cheek patch. A ragged dark chestnut stripe extended from
the upper breast all the way along the side to the flank. The rest of the
underparts were pure white. The back was grayish olive and was prominently
marked with black streaks. The wings were dark gray with two broad
yellowish wingbars. Its voice was a rapid (for a warbler)
"we-cheepa, cheepa-cheepa-cheepa," the last note dropping.
There are four records for the Oregon Coast: one record in late May,
one in early June, one in mid-June, and one in mid-September (Schmidt
1989:93-94). Eltzroth (1987:15) lists them as vagrants along the Oregon
Coast.

The records above include records of the Audubon's and Myrtle forms of
Yellow-rumped Warblers below. The only record of this species nesting here
was for a nest of Audubon's in about 1971.
It was erratically present in winter; more often, it was just a spring
and fall migrant.

On the days following their arrival each year, they were usually
present. For example, the previous tabulation indicates that they were
found an average of 72% of the days in the 10 day period after their
arrival.
The probability that they would be present near their average
arrival date each year was moderate because their average daily presence
was 46% during the five day period before and after their average arrival
date (Table 5.2). However, they were usually found each year on their
average arrival date and 1-5 days thereafter (Table 5.2).
Prior to their departure, they were often absent. For instance, they
were found on an average of only 24% of the days in the 10 days preceding
their departure.
In 1973-1976, Faxon was just learning their calls, so that is the
reason for the few records then. Accordingly, the May "arrivals" then
have been excluded because these warblers probably arrived in April like
they did in 1977-1988.
Their Average Daily Frequency was greatest in May, and this may be a
result of many migrants passing through or because they were singing more
then. Most of the records were based on song rather than on sightings.
They could be common during fall migration "waves" (section 5-G-3).
Adults were sometimes observed feeding fledgling Brown-headed
Cowbirds (section 6-B-184).

Townsend's appeared to be mainly fall migrants, but they were also
noted in May of five different years, so they were also spring migrants
sometimes.
They were sometimes present during fall migration "waves"
(section 5-G-3).
In 1989, two were noted on January 17, and a flock of eight were
recorded on October 24.
Faxon believes that the increased number of records in recent years
is because he started imitating No. Pygmy-Owl calls to attract birds, and
one of the species attracted was the Townsend's Warbler.

UNCONFIRMED.--One bird was seen on 19 August 1977 that was an
immature with an exceptionally greenish back unlike that of Townsend's
or Hermit warblers. The crown was olive-green, and on the side of the
bird's head was a conspicuous triangle surrounded by yellow; this
triangle was shaped differently from that of a Townsend's Warbler. The
throat and breast were whitish, and its belly was tinged with yellow. The
wings were grayish with two broad white wingbars. The tail was
grayish-olive with the outer feathers appearing white.
There is one record accepted by the Oregon Bird Records Committee for
the Oregon Coast in October (Schmidt 1989:98), and it is listed as a
vagrant along the Oregon Coast by Eltzroth (1987:15).

UNCONFIRMED.--A male sang from 9 AM to noon on 24 May 1989. It had a
black throat and breast, black streaking on its sides, and a white face
broken by a black eye and ear patch. The black crown was broken by a white
central stripe. Its upperparts were black and profusely striped with
white. It had black wings with two broad white wing bars. Its belly
was white. It was closely observed for about 10 minutes and was present
for about three hours. Eltzroth (1987:15) lists it as extremely rare
along the Oregon Coast; most records of this species in Oregon are in May
(Schmidt 1989:105).

UNCONFIRMED.--Two were seen on 14 October 1976. They were large for a
warbler with the upper parts grayish olive throughout, no wing bars, and the
head only slightly darker than the upper parts. They had a conspicuous
complete white eye-ring. Their throats showed the cutoff line on the
breast suggestive of a hood, but the color was pretty washed out and
appeared dull whitish. The rest of the underparts were entirely yellow.
They gave a call note several times, which was a distinctive "chip,"
similar to that of the Yellow-rumped Warbler, but also louder and different
from the call note of the MacGillivray's.
There are no Oregon Coast records that have been documented by the
Oregon Bird Records Committee (Schmidt 1989:109), but they are rare
visitants to the Farallon Islands in California in May-June and
September-October (DeSante and Ainley 1980).

They were most often seen in clearcuts less than about two years old
or in brush with less than complete ground cover.
There were never more than about three pairs. Between 1980 and 1983,
they were not noted as breeding birds; their breeding status from 1983
onward is not clear.
In some years, they appeared to be only spring and fall migrants.
Since they were not always present every year prior to 1988, their
low presence in 1988 and their absence in 1989 may be part of a down
cycle rather than representing a continuing decline.

Faxon notes that this species has become more abundant in recent
years; their increased Monthly Frequencies were not a result of changes
in observation effort.
Faxon has not found any evidence of their breeding here. In some
years they appeared to be only a spring and fall migrant.

three days after the vagrant Black-throated Green Warbler (section 6-B-153)
passed through.
The Oregon Bird Records Committee has not accepted any records for the

following the Thornton Creek record in Sept. 1975 at the Farallon Islands
(DeSante and Ainley 1980).

On the days following their arrival each year, they were usually
present.For example, the previous tabulation indicates that they were
found an average of 98% of the days in the 10 day period after their
arrival.
The probability that they would be present near their average arrival
date each year was moderate because their average daily presence was 46%
during the five day period before and after their average arrival date
(Table 5.2). However, they were usually found each year 2-5 days after
their average arrival date (Table 5.2).
Prior to their departure, they were often present. For instance,
they were found an average of 67% of the days in the 10 days preceding
their departure.
They could be common during fall migration "waves" (section 5-G-3).

Clearly, their Average Daily Frequencies were lowest during summer
(June-September), even though they were usually present in these months.
Faxon thinks that they have an altitudinal migration here in summer
in which they forsake the valleys but are found on brushy ridges. Bayer
wonders if this change may be unrelated to elevation but may be a change
in preferred habitat.
