9.0 Birds the Brown Pelican population since the mid-1980s that has been linked to the ban of DDT (Burkett et al. 2007). 9.4.2.2 9.4.2.3 9.4.2.4 9.4.2.5 Double-crested Cormorant The double-crested Cormorant was among the most numerous species recorded within the Ports during the 2007–2008 surveys, accounting for 3.5% of all birds counted (Table 9.4-1). This species nested on transmission towers north of the Gerald Desmond Bridge in Zones 25 and 26 of inner Long Beach Harbor; 89 nests were counted in Zone 26 on June 20 and 16 were counted in Zone 25 on July 26. Great Blue Heron Great Blue Herons were the most numerous Wading/Marsh Bird, and accounted for 0.8% of total birds counted in 2007–2008 (Table 9.4-1). During the 2000–2001 baseline study (MEC 2002), Great Blue Herons were observed nesting along with Black-crowned Night Herons within the Port of Long Beach at Gull Park on the Navy Mole, at the mouth of the Long Beach West Basin. They have continued to nest there annually; an estimated eight Great Blue Herons nested at Gull Park in 2007, with a minimum of 15 chicks fledged (MBC 2007). In 2008 there were seven nests, and seven to 14 young fledged (C. Pacquette, pers. comm.). Great Blue Heron nesting also was documented in several other areas of the Ports during 2007–2008 surveys, including Zone 2 (a maximum of 7 nests), Zone 4 (6 nests), Zone 7 (4 nests), and Zone 8 (on container terminal security lights) in outer Los Angeles Harbor, and Zone 26 (14 nests) in inner Long Beach Harbor. Black-crowned Night Heron A nesting colony of Black-crowned Night Herons was observed at Gull Park at the mouth of the Long Beach West Basin during the 2000–2001 baseline study (MEC 2002). None were observed nesting at this location during the 2007–2008 surveys. This species had apparently discontinued nesting in 2002 following a Navy remediation project at Gull Park in 2001; aside from one nest in 2002, no Black-crowned Night Heron nesting activities were observed during yearly surveys at Gull Park from 2002 through 2008 (MBC 2007, C. Pacquette, pers. comm). However, Black-crowned Night Herons were documented as nesting in 2008 in other nearby areas, including ficus trees adjacent to the federal building on Ferry Street (Keane Biological Consulting 2008). Peregrine Falcon Although no Peregrine Falcons were observed during the 1986–1987 biological baseline surveys (MEC 1988), this species was reported to occur within the Ports as early as 1982, and a single individual was documented in 1984 (ACOE 1984, MBC 1984). Nesting has been documented within the Ports since 1993 (J. Sipple, pers. comm.). Peregrine falcons have nested on the Schuyler F. Heim Bridge that separates the Ports of Long Beach and Los Angeles inner harbors. A pair of peregrine falcons has nested within the supporting structure below the Gerald Desmond Bridge off and on for the past several years, and they have successfully fledged young each year (Jeff Sipple, pers. comm.). During the 2007–2008 surveys, one or more Peregrine Falcons was observed on 11 of the 20 survey dates, with the majority either flying or roosting on bridges (Figure 9.4-1b), including one observation of nesting on June 20 at the Gerald Desmond Bridge in Zone 25 of inner Long Beach Harbor. 2008 Biological Surveys of Los Angeles and Long Beach Harbors 9–5 April 2010
9.0 Birds 9.4.2.6 9.4.2.7 9.4.2.8 9.4.2.9 Western Snowy Plover No Western Snowy Plovers were observed within the Ports during the 2007–2008 surveys. This species is occasionally observed during migration at the California Least Tern nesting site on Pier 400 (Keane Biological Consulting 2007). A few individuals also have been observed at Point Fermin and Cabrillo Beach outside the breakwater (Ryan et al. 2009). Black Oystercatcher Similar to the 2000–2001 surveys (MEC 2002), a nesting colony of Black Oystercatchers was observed on riprap along the entire length of the outer breakwaters within the both Ports (Zones 15, 12, 9, 3, 2) (Appendix H-2). Black Oystercatchers were also sometimes observed at other outer harbor locations in flight or on riprap (Zones 7, 8, 10, 19, 21). The species has been present within the Ports since at least 1973 (HEP 1979). Black Oystercatchers were the most common large shorebird observed in 2007–2008 (0.6% of all birds) (Table 9.4-1). Individuals were observed on all survey dates, with the highest number during July and August 2008 (Figure 9.4-1c), likely reflecting the presence of fledged chicks. Lower numbers of individuals were observed from October through December, but individuals remained concentrated along the breakwater. Black Oystercatchers typically nest along rocky shores and islands along the Pacific coast of North America (Pacific Wildlife Foundation 2009) and the nesting colony within the Ports is considered unusual. Caspian Tern Caspian Terns began nesting at Pier 400 in the Los Angeles Harbor in 1997 (Keane Biological Consulting 2005). This species continued to nest annually at or near the designated California Least Tern nesting site on Pier 400 (west area of Zone 8) until 2005 (Table 9.4-3), when they left the area due to a nocturnal predator (Keane Biological Consulting 2005). They nested once again in the Los Angeles Harbor in 2008 (Table 9.4-3), but did so on Pier 300 near Berth 305 (between Zones 6 and 7). The highest numbers of Caspian Terns were observed during May through August 2008 when they were nesting on Pier 300, although relatively high numbers also were counted in March (Figure 9.4-1d). Caspian Terns foraged most frequently in Zones 6 & 7, close to where they were nesting on Pier 305 (Table H-22). Elegant Tern The Elegant Tern was one of the most numerous bird species overall (7% of total birds), the second most numerous aerial fish forager, and the most numerous of the observed tern species (Table 9.4-1). Elegant Terns are a colonially nesting species with a relatively restricted distribution; 90 percent of their total population breeds at five southern California sites (MEC 2002). This species nested on Pier 400 in the Los Angeles Harbor between 1998 and 2005 and at Pier 300 in 2008 (Table 9.4-3). Numerous observations during 2007–2008 surveys of Elegant Tern flights over the breakwaters suggest they forage primarily outside the harbor, although they occasionally were observed foraging within the Ports. Elegant Terns are unusual in coastal southern California in the winter (C. Collins, pers. comm.), and 2007–2008 surveys reflected this, with no Elegant Terns observed during the December, January, February, or early March surveys (Figure 9.4-1e). Historical records of occurrence during those months may represent misidentified Royal Terns. High numbers of Elegant Terns roosted on the Ports’ breakwaters with newly fledged young from June to early August (riprap; Figure 9.4-1e). Observations suggest that young Elegant Terns learn to forage with their parents in waters near the riprap. Similar to Caspian terns, Elegant Terns foraged most frequently in Zones 6 & 7, close to where they were nesting on Pier 305 (Table H-22). 9–6 2008 Biological Surveys of Los Angeles and Long Beach Harbors April 2010
