Swamis, Encinitas, CA December 27, 2009.
Area Covered: 1) Western portion of San Elijo Lagoon (WSEL: 0739-0910; 1610-1648 hrs). We walked all the trails
beginning at the visitor center, surveying estuarine marsh, sloughs, open water, riparian and coastal sage scrub habitats.
Morning survey at high tide; afternoon survey at low tide. Used binoculars, scope and DSLR camera. Conditions on the trails
were generally good for detecting bird vocalizations; a few hikers on the trails, otherwise quiet during the surveys.
2) Eastern portion of San Elijo Lagoon (ESEL: 1529-1610 hrs.): From the parking lot at Mira Costa College, we crossed the busy roadway
and entered the trail bisecting the marsh into east and west halves. Our survey included parkland habitat at Mira Costa College,
adjacent coastal sage scrub and farmland, marshland and open water, using binoculars, scope and DSLR camera. Aside from
one other photographer and two hikers, the trails were vacant and conditions good for observing birds at close range. The purpose of our visit to the lagoon this afternoon was mainly to find species we may have overlooked this morning at high tide at WSEL and find new species for our day-list at ESEL.

IMPERIAL BEACH AND LA JOLLA (24 Species)
December 28, 2009
Weather: Fair, 65 to 70F. Winds WNW 5-7 mph. High Tide at about 1030 hrs. Surf 6-10 ft.
Time: 0940-1040 hrs (IMP); 1230-1450 hrs. (LJ).
Observers: Merissa Mendez and me.
Area Covered: 1) Imperial Beach and Pier (IMP): We parked about 1/2 mile north of the Imperial Beach Pier and walked south on the beach to the Pier, surveying
nearshore waters, breakwaters and the beach (fairly crowded with families). We used binoculars, scope and a DSLR camera. The pier was
undergoing noisy renovations at both ends, but was passable with brief delays while workmen replaced the boardwalk planks. A few fishermen and a steady stream of visitors were on the pier during our survey. Visibility was good for scoping the near-shore waters, but the vibrations from foot traffic and heavy surf made identifications of distant birds difficult 2) We drove into the congested streets of LaJolla (LJ)and parked near the shore overlooking tidal flats. After lunch, we walked through the town, surveying gardens using binoculars, then down along the path overlooking Children's Beach and cove, which was crowded with visitors. Birdlife was minimal; the big attraction was a large group of harbor seals hauled out on the beach and a couple of young surfers off the point.

CABRILLO NATIONAL MONUMENT
POINT LOMA (23 Species)
December 29, 2009
Weather: Mostly sunny. 60 to 64F; WNW winds 5-12 mph. Surf 3-5 ft.
Time: 1030-1337 hrs.
Observers: Merissa Mendez and me.
Area Covered: 1) Cabrillo National Monument visitor center and surrounding coastal sage scrub (VC). We walked the trails around the visitor center
surveying pines, coastal sage scrub on exposed hilltops with panoramic views of San Diego and the coastline, using binoculars. Hundreds of holiday visitors in the monument during our survey. Birdlife was nonetheless abundant, especially in the gardens around the visitor center. 2) We then drove down to the northernmost
parking area along the western shoreline of Point Loma (PL)and walked the roadway and trail S along the cliffs overlooking tidepools and the nearshore waters. Rocks along the shore were pounded by heavy surf, leaving little space for shorebirds to forage. And combined with the large number of people in the tidepool areas (still a relatively high tide), birdlife was restricted mostly to the inaccessible cliffs and outside of the surf zone. Surveyed the coastal sage scrub along the cliffs and upslope of
the paved roadway.

BATIQUITOS LAGOON, CARLSBAD-ENCINITAS (61 Species)
December 30, 2009
Weather: Overcast with light rain beginning at 1300 hrs. 63F. Winds WNW 5-10 mph. High Tide at about 1100 hrs.
Time: 0900-1240 hrs.
Observers: Merissa Mendez and me.
Area Covered: From a small parking area on Gabbiano Rd., between Encinitas and Carlsbad, we walked into the 610-acre Batiquitos Lagoon Ecological Reserve (BL), using the trails covering the northwest northern and northeastern shoreline (about 2.4 miles round-trip). We surveyed small sections of adjacent suburban gardens, coastal sage scrub, extensive Eucalyptus woodland bordering an estuarine marshland, mudflats (mostly in the NEC), shoreline, 300 + acres of open water and an isolated riparian strip (about 20 acres) in the eastern portion the lagoon, bordering El Camino Real. We used binoculars, scope and a DSLR camera. Numerous walkers (many with leashed dogs), joggers and a few casual birders were on the trails. Conditions for detecting birds and their vocalizations were generally favorable, except in the northwest corner near I-5, which was overwhelmingly noisy. The Aviara country club parallels the main northshore trail for about 1/3 mile; one section of the BL trail regularly receives stray golf balls, and could not be safely surveyed (a walker ahead of us was nearly struck by a golf ball ricocheting off a Eucalyptus tree). Aviara also has a small artificial pond divided by a waterfall, visible from the BL trail, which contained bird species not found elsewhere during our survey (e.g. Green Heron and Spotted Sandpiper).Folks on the trails seemed friendly; a couple of them asked in passing what birds we had seen. However, as I have observed throughout California, most users of these wonderful ecological reserves appear to have little or no knowledge of the diverse community of plants and animals they support. Trail systems (often laboriously constructed and maintained by volunteers) are simply popular locations for a run or walking the dog. Visitor centers, often stocked with checklists, specimens, maps and natural history guides, are often bypassed or used primarily as a convenience store.
Back at the western BL trail head, we entered the small, but well-appointed visitor center and spoke with Robin, a volunteer who was finishing her shift. Robin, a recent immigrant from NYC, has taken a keen interest in the natural history of the lagoon and eagerly recorded one of our unusual sightings (.Stercorarius sp.) Handing us the May, 2004 checklist, Robin mentioned that about 300 species of bird have been recorded at BL (only 181 species are shown on the May, 2004 list; no species of Jaeger (Stercorarius) was on this list).
We subsequently drove to the east end of the lagoon and parked on a narrow, raised shoulder of El Camino Real, where I attempted (unsuccessfully) to obtain a usable photograph of a pair of White-tailed Kites seen there earlier through the scope from the northshore trail. Light showers began at about this time, forcing us to abandon further observations of birds using this relatively isolated, trail-less section of BL.

Seen at a distance of 50-80 yards when I was studying a group of sleeping shorebirds with a 35-55x Nikon spotting scope mounted on a sturdy (Bogen #3126) tripod. First sighting at about 1100 hrs. for 20 seconds or less. The bird was seen again for a few seconds about 10 minutes later to the NEC where hundreds of shorebirds were resting, again causing much disturbance with vocalizations and flights westward over the lagoon.

TIJUANA SLOUGH NATIONAL WILDLIFE REFUGE (56 Species)
December 31, 2009
Cooper's Hawk (Accipiter cooperii) TSNWR Dec. 31, 2009
© 2009 Callyn D. Yorke
Weather: Fair. 60 to 65F. Winds WNW 2-5 mph. High Tide about 1130 AM.
Time: 1030-1330 hrs.
Observers: Merissa Mendez and me.
Area Covered: 1) Tijuana Slough NWR, Imperial Beach (TSNWR): We walked all the accessible trails (i.e. branches of the North McCoy Trail) through the reserve, first to the NW corner with a small riparian and suburban edge, then SE through the extensive marshland. A deep slough (without a bridge we could find) separates North and South McCoy trails.We also walked along the eastern border (5th Street) with fenced yards and a fenced airfield. Habitats surveyed, using binoculars, scope and DSLR camera, included suburban gardens and mature pines, riparian, saltbush scrub, coastal sage-Cholla cactus scrub, marshland, sloughs and short grassland within the fenced airfield property. After our survey we picked up a bird checklist and information brochures at the attractive and educationally well-supplied visitor center. We walked a total distance of about 1.5 miles through the refuge.
A day-list of unusual bird sightings was posted inside the visitor center. The male Hepatic Tanager we found earlier in the pines by the apartment complex, had already been noted with other sightings (e.g. Mountain Plover - a species we did not see). The McCoy trail was fairly busy with cyclists (illegal), dogs and their owners (all but two dogs were leashed), hikers, joggers and a couple of wildlife photographers during our survey. 2) We then drove E on Imperial Beach Boulevard and south on Hollister Street (HS), stopping briefly at the entrance to Border Field State Park (BFSP: The Monument Road entrance was predictably closed; gate locked) and Tijuana River Valley County Park (TRVCP) with an impressive entry sign but without maintained trails or facilities. These areas form part of the Tijuana River drainage system and offer a variety of habitats we did not find at TSNWR (e.g. pastures, corrals, mature riparian and coastal sage scrub).

CORONADO ISLAND AND SOUTH SAN DIEGO BAY (77 Species)

Weather: Fair. 55-65F; winds WNW 5-15 mph. High Tide at about 1130 hrs.
Time: 0930-1500 hrs.
Observers: Merissa Mendez and me.
Area Covered: We found free, unlimited parking in a residential area on Ardella Street, a few blocks E of the Hotel Coronado, where we enjoyed a tasty buffet breakfast.. Afterwards, we cycled through the mature, tree-lined streets of suburban Coronado Island (CI) down to Coronado Harbor (CH) and along the west shore of South San Diego Bay on the paved, two-lane Bayshore Bike Trail, (BBT)stopping frequently to observe and photograph birds along the shore, marshland and open water. We also included a brief visit to Silver Strand State Beach (SS) to survey the outer coast and nearshore waters. Continuing southward, we reached the South Bay Bay Marine Biology Study Area (SBMBSA) where a system of levees enclose shallow lagoons. The southern section of the bike route goes through a residental area, a fenced corridor, salt evaporation ponds, and a brackish drainage ditch, before meeting open fields at the junction of I-5, where we stopped for lunch. We returned along the same route, cycling into a steady 15 mph headwind. The return trip, though tiresome due to the wind, afforded views of the extensively exposed western mudflats at low tide. There were many other cyclists, walkers and joggers using the bikeway during our survey; most of the traffic was at the north end of the route between Lowe's Resort and Coronado Harbor. Conditions were generally favorable for observing birds with only binoculars, though a scope would have been helpful at times. A few observation platforms along the route alowed close-up views of birds with excellent photographic opportunities.We covered a round-trip distance of about 12 miles.
