Subject: Results of the 2013 Least Bell’s Vireo and Southwestern Willow Flycatcher Surveys for the Arroyo Seco Canyon Project in the City of Pasadena, Los Angeles County, California

Dear Mr. Rydman:

This Letter Report presents the results of focused surveys to determine the presence or absence of the least Bell’s vireo (Vireo bellii pusillus) and southwestern willow flycatcher (Empidonax traillii extimus) on the Arroyo Seco Canyon Project Site (hereinafter referred to as the “Project Site”). A Biologist with the necessary experience and the Federal Endangered Species Act Section 10(a) survey permit conducted the surveys according to U.S. Fish and Wildlife Service (USFWS) protocol for these species.

The Arroyo Seco Canyon Project will increase the utilization of surface water rights held by the City of Pasadena Water and Power Department (PWP) and the Lincoln Avenue Water Company (LAWC) by restoring and improving the intake facilities; modifying the existing sediment removal mechanism; naturalizing the Arroyo Seco streambed; and expanding recharge operations by creating additional spreading basins. In addition, the Project is planned to include a new public restroom facility with recreational and educational amenities near the Headworks structure, as well as a new reduced size parking lot at the existing Jet Propulsion Laboratory (JPL) parking site for those using the Arroyo Seco Canyon and Hahamongna Watershed Park area. The Project Site is in the City of Pasadena and is located on the U.S. Geological Survey’s (USGS’) Pasadena 7.5-minute quadrangle map (Exhibit 1).

Species Background

The southwestern willow flycatcher and least Bell’s vireo were formerly more common and widespread, but became rare and local summer residents of Southern California’s lowland riparian woodlands (Grinnell and Miller 1986; Garrett and Dunn 1981). The substantial population declines of these two avian species over the latter half of the twentieth century is attributable to the loss and degradation of riparian habitats and to brood parasitism by the brown-headed cowbird (Molothrus ater) (Garrett and Dunn 1981; USFWS 1995). As a result, the California Department of Fish and Wildlife (CDFW) and the USFWS consider least Bell’s vireo to be an Endangered species, as listed on October 2, 1980, and May 2, 1986, respectively (CDFW 2013). The CDFW considers all three subspecies of willow flycatcher that breed in California (E. t. brewsteri, E. t. extimus, and E. t. adastus) to be Endangered (as listed on January 2, 1991), and the USFWS considers the southwestern willow flycatcher (E. t. extimus) to be Endangered, as listed on March 29, 1995 (CDFW 2013).

Least Bell’s Vireo

Bell’s vireo is a Neotropical migrant that breeds in central and southwestern North America from northern Mexico to Southern California, Nevada, and Utah; east to Louisiana; and north to North Dakota, Wisconsin, and Indiana in the central U.S. (AOU 1998). Although not well known, the winter range of the Bell’s vireo is believed to be the west coast of Central America from southern Sonora south to northwestern Nicaragua, including the cape region of Baja California, Mexico (Brown 1993). Of the four Bell’s vireo subspecies, only two breed in California: the least Bell’s vireo and the Arizona Bell’s vireo (V. b. arizonae); the latter breeds in the Colorado River Valley (Garrett and Dunn 1981; Rosenberg et al. 1991). Though the least Bell’s vireo was formerly considered a common breeder in riparian habitats throughout the Central Valley and other low-elevation riverine systems in California and Baja California, Mexico (Franzreb 1989), the least Bell’s vireo had been eliminated from much of its historical range at the time of listing (Franzreb 1989; Brown 1993). The least Bell’s vireo has increased tenfold since its listing to 2,968 territories, and it has begun to recolonize portions of its former range where it had been extirpated (USFWS 2006). The increase is credited to improvements in habitat abundance and quality and effective cowbird control. Continued cowbird control and exotic plant removal in riparian areas are considered necessary for the foreseeable future in order to continue this trend (USFWS 2006).

The breeding habitat of the least Bell’s vireo is primarily riparian dominated by willows with dense understory vegetation; shrubs such as mule fat (Baccharis salicifolia) and California rose (Rosa californica) are often a component of the understory (Goldwasser 1981). The least Bell’s vireo is often found in areas that include trees such as willow (Salix spp.), western sycamore (Platanus racemosa), or cottonwood (Populus sp.), particularly where the canopy is within or immediately adjacent to an understory layer of vegetation (Salata 1983). The least Bell’s vireo generally nests in early successional stages of riparian habitats, with nest sites frequently located in willows that are between four and ten years of age (RECON 1988; Franzreb 1989). The most critical factor in habitat structure is the presence of a dense understory shrub layer from approximately two to ten feet above ground (Goldwasser 1981; Salata 1983; Franzreb 1989).

On February 2, 1994, the USFWS issued their final determination of critical habitat for the least Bell’s vireo (USFWS 1994), identifying approximately 37,560 acres as critical habitat in Santa Barbara, Ventura, Los Angeles, San Bernardino, Riverside, and San Diego Counties. The Project Site is not located within designated critical habitat for this species.

Southwestern Willow Flycatcher

The willow flycatcher is a Neotropical migrant that breeds in the west from northern Baja California, Mexico to central British Colombia, and generally east through the northern half of the U.S. to the Atlantic coast (AOU 1998). Depending on the authority, there are four or five recognized subspecies of willow flycatcher (Sedgwick 2000). The breeding range of southwestern willow flycatcher includes Southern California, Arizona, New Mexico, western Texas, and the extreme southern parts of Nevada and Utah (USFWS 1993). In California, the southwestern willow flycatcher breeds along the coast north to the Santa Ynez River in Santa Barbara County, and north in the interior to about Independence in Inyo County (USFWS 2002; Unitt 1987). The largest breeding populations of southwestern willow flycatcher in California are located at the South Fork of the Kern River in Kern County and on the Santa Margarita River in Camp Pendleton in San Diego County (Unitt 1987). The range-wide population of southwestern willow flycatcher is estimated at 1,299 territories at 288 sites (Durst et. al. 2008). The population of southwestern willow flycatcher in California is estimated to be


about 172 territories at 96 sites (Durst et al. 2008). Within the Coastal California Recovery Unit, the population is estimated at 120 territories at 73 sites (Durst et al. 2008). The southwestern willow flycatcher population has not shown the same recovery that the least Bell’s vireo has shown in response to riparian habitat restoration and cowbird control (Kus 2011).

The southwestern willow flycatcher breeds in willow-dominated riparian habitats that are similar to least Bell’s vireo nesting habitats. The southwestern willow flycatcher differs from least Bell’s vireo in that it shows a stronger dependency on willow thickets for all its requirements (Grinnell and Miller 1986). In addition, the southwestern willow flycatcher appears to have a preference for sites with surface water in the vicinity, such as along streams; on the margins of a pond or lake; and at wet mountain meadows (Grinnell and Miller 1986; Flett and Sanders 1987; Harris et al. 1987). In Arizona, the southwestern willow flycatcher invariably nests near surface water (Phillips et al. 1964). The southwestern willow flycatcher has also adapted to introduced vegetation present in riparian communities, such as tamarisk (Tamarix sp.) and Russian olive (Elaeagnus angustifolia) (USFWS 1993).

The willow flycatcher is a common migrant in the interior of California and a rare-to-uncommon migrant along the coastal slope, with most birds moving through Southern California between May 15 and June 20 (Garrett and Dunn 1981; Unitt 1987). The spring migration of southwestern willow flycatcher is earlier than that of the northern subspecies (Unitt 1984; USFWS 1993). As a result, the presence of more abundant subspecies that migrate through the range of the southwestern willow flycatcher during its breeding season complicates surveys for nesting southwestern willow flycatchers.

On October 19, 2005, the USFWS published a Final Rule designating critical habitat for the southwestern willow flycatcher (USFWS 2005). This final rule designated 120,824 acres in Arizona, California, Nevada, New Mexico, and Utah as critical habitat. Of that, 17,212 acres were designated as Critical Habitat in Kern, Santa Barbara, San Bernardino, and San Diego Counties, California. Following lawsuits, the USFWS recently issued a revised Final Rule on January 3, 2013. This Final Rule designates critical habitat that covers 2,090 stream miles in California, Nevada, Utah, Colorado, Arizona, and New Mexico (USFWS 2013). This Final Rule uses a slightly different methodology to designate critical habitat. For example, it includes areas that are considered essential for the recovery of the species, even if they were not occupied at the time of the species’ listing. The Project Site is not located within the previous final critical habitat designation or the 2013 revised critical habitat designation.

Survey Methodology

The USFWS survey protocol for the least Bell’s vireo requires that at least eight surveys be conducted from April 10 to July 31 with a ten-day interval between each. The USFWS protocol for the southwestern willow flycatcher requires a total of five surveys, with the first survey conducted between May 15 and May 31; the second and third surveys between June 1 and June 24; and the fourth and fifth surveys between June 25 and July 17. Due to similar ecological requirements, surveys for these two species can be conducted concurrently. A total of nine surveys were conducted to fully satisfy the survey requirements of both species. BonTerra Consulting Senior Biologist Brian Daniels (Permit No. TE 821401-4) conducted the five southwestern willow flycatcher surveys on May 28; June 14, 19; and July 2, and 12, 2013. BonTerra Consulting Senior Biologist Marc Blain and BonTerra Consulting Biologist Sarah Thomas conducted the third least Bell’s vireo survey on May 2; Ms. Thomas conducted the fourth least Bell’s vireo survey on May 14, 2013; and Mr. Daniels conducted the least Bell’s vireo surveys on April 11 and 22, May 28, June 14 and 19, and July 2 and 12, 2013.


The survey areas for the Project Site include riparian habitat within four separate areas along the Arroyo Seco (as shown in Exhibit 1). Area 1 encompasses an area along and to the west of the Arroyo Seco stream near the U.S. Forest Service Ranger Station. The Arroyo Seco Headworks structure is located in this segment of the stream. Area 2 is referred to as the Arroyo Seco Intake and is located approximately ¼ mile downstream from the Headworks. The Temporary Staging Site is located approximately 900 feet downstream from the Arroyo Seco Intake area and encompasses a small area immediately south of the confluence of Millard Canyon and the Arroyo Seco stream. Area 3, the John L. Behner Treatment Plant study area, is located about 740 feet south of the Temporary Staging Site and includes the JPL parking lot and adjacent recharge basins. Riparian habitats adjacent to the access road (Gabrielino Trail) were also included in the survey area. The approximate 6,110-foot length of riparian habitats were systematically surveyed by walking slowly and methodically along the margins of riparian habitat and by using meandering transects through riparian habitat. Following the willow flycatcher protocol, recorded vocalizations were used to elicit a response from any potentially territorial southwestern willow flycatchers. If no southwestern willow flycatchers were detected after the initial playing of the recorded vocalization, Mr. Daniels replayed the recording at least once, but often multiple times. As the least Bell’s vireo survey protocol does not require the playback of least Bell’s vireo vocalizations, recorded least Bell’s vireo vocalizations were not used during those surveys.

All surveys were conducted under optimal weather conditions (i.e., between 52 and 73 degrees Fahrenheit [°F] with wind speeds between 0 and 3 miles per hour) and during the early morning hours when bird activity is at a peak.

Survey Results

No breeding least Bell’s vireos or southwestern willow flycatchers were detected during the surveys. No migrant willow flycatchers were observed during the surveys. Daily tallies indicating relative abundance for bird species detected during the surveys are presented in Table A-1 of Attachment A. Representative site photos are presented in Attachment B.

Riparian habitats in Area 1 are dominated by willows (Salix sp.). Willows are scarce in the other survey areas, but there are some in the central portion of Area 2 (see Project Photos in Attachment B). The riparian habitats within, and adjacent to, Area 2 and the Temporary Staging Site are dominated by white alder (Alnus rhombifollia) and western sycamore (Platanus racemosa). Area 3 contains sparse western sycamores and a small patch of mule fat thickets and some alder and willow trees are found within 500 feet of the survey area.

The list of 83 species of birds identified during these surveys includes 1 species, the yellow warbler (Setophaga petechia), that is listed by the CDFW as Species of Special Concern (Shuford and Gardali 2008). Three breeding territories were identified in the mature willow woodland in Area 1. Additionally, one amphibian—coast range newt, also a CDFW Species of Special Concern—was identified within Area 1. As required by BonTerra Consulting’s Letter of Agreement with the CDFW, California Natural Diversity Database (CNDDB) forms have been completed and submitted to the CDFW documenting these occurrences (Attachment C).
