OCTOBER 10, 12 & 14, 2012 (53 Species)
Weather:(10/10) Partly cloudy; 71F; wind W, WNW 5 -12 mph. (10/12) Partly cloudy, 50F; wind WSW 5 - 10 mph.(10/14): Fair; 51F to 70F; wind WNW 0-2mph.
Time: (10/10) 1449 - 1600 hrs.; (10/12) 0725-0940 hrs.(10/14): 0815-1135 hrs.
Area Covered: (10/10): I walked a counter-clockwise route once around the perimeter of the park. About 30 people were in the park, including children and their parents feeding birds at the main beach. Conditions were fair to poor for finding birds; increasing west winds and noise from the adjacent airfield made observations somewhat difficult. (10/12): I walked a clockwise route around the entire lake, then through the central section. Several people with dogs (one unleashed) and some joggers were in the park during my survey.(10/14): I began walking an counter-clockwise route then reversed at the southeast corner and completed a full clockwise circuit. Following a brief interlude in my car, I walked a full counter-clockwise route around the perimeter, excluding the interior pathways, which were scanned from a distance. Increasing numbers of visitors began arriving around 0930 hrs. many with leashed dogs. Several children and adults were feeding the ducks and geese on the main beach. Others were seen chasing geese (including Canada Goose). Conditions in the park were otherwise good (light air traffic from the adjacent airfield) for finding birds.
Summarized below is the bird list covering three separate surveys I conducted in Apollo Park on 10/10, 10/12 and 10/14/2012. My intent is to illustrate migration dynamics in the Antelope Valley during the first half of October. Several migratory species showed up abundantly and consistently during this period (e.g. Double-crested Cormorant, American Coot, Red-breasted Nuthatch,Yellow-rumped Warbler, White-crowned Sparrow), while others appeared sparsely or intermittently (e.g. Snowy Egret, Ring-billed Gull, Sage Sparrow, Lark Sparrow). Rarities found during this period included, Cackling Goose, Magnolia Warbler (previously unrecorded at Apollo Park) and White-throated Sparrow. Of course the differences in weather, survey schedule and detectability are likely contributing factors to the observed results.
Birds of seasonal and/or distributional interest found on 10/10 included, Greater White-fronted Goose (1- cont.), Snow Goose (1 -cont.), Ross's Goose (2 -cont.), American White Pelican (2), Snowy Egret (6), White-throated Sparrow (1) and Dark-eyed (Oregon) Junco (2). Additional species of seasonal and/or distributional interest found on 10/12 included, Great Egret (7), Western Wood Pewee (1), Empidonax sp. (1), Red-breasted Nuthatch (8), Mountain Chickadee (2), American Pipit (1), and Black-throated Gray Warbler (1 dead). The White-throated Sparrow photographed here on 10/10 was not found. Birds found on one or the other survey are indicated below. Additional species of seasonal and/or distributional interest found on 10/14 included, American Wigeon (2), Aleutian Cackling Goose (1), Pacific Slope Flycatcher (1), and Magnolia Warbler (1).
Apollo Park is scheduled to be closed for maintenance, October 22 - November 3, 2012.
BIRDS NOTED
Aleutian Cackling Goose (Branta hutchinsii) 1 foraging on the lawn, n (10/14 - possibly overlooked during previous two surveys).
Canada Goose (Branta canadensis) 40-50 foraging on lawns, swimming, n. One small individual, a relatively small variety of Canada Goose (Branta canadensis c.f. taverneri), with a round head, moderate-sized bill, plain breast and no white basal neck ring, was found with others on the n lawn. (photo).This particular individual was observed chasing a much larger Canada Goose across the lawn, suggesting intraspecific rather than interspecific aggression (see the following commentary).
Commentary: The current A.O.U. classification (45th supplement to the A.O.U. checklist of North American Birds) places traverneri with the Cackling Goose (Branta hutchinsii) group. This widespread group of generally small Canada geese appears to share significant molecular and geographic similarities. However, according to the most fundamental working definition of a biological species, naturally occuring populations are reproductively isolated from one another. Molecular biologists, in contrast with experienced field biologists, may overlook this important distinction. Thus, while molecular comparisons can be very useful for clarifying evolutionary relationships among higher taxonomic groups (e.g. orders, families and genera), and possibly species and populations, these data should not necessarily be given more statistical weight than other characteristics (e.g. morphology, behavior, ecology and biogeography) when determining if a taxon should be lumped or split at the level of species. I accept the specific separation of at least some populations of the Canada Goose, such as the Aleutian hutchinsii based on morphology and insular breeding of that population (also supported by molecular evidence). However, several other populations of the Canada Goose (e.g. moffitti, parvipes, taverneri) show overlap morphologically, behaviorally and geographically and may not be by definition distinct from the Canada Goose (Branta canadensis). Again, reproductive isolation is the bottom line in terms of assigning specific status. If unknown, it seems prudent and consistent with the objectives of taxonomy (e.g. information retrieval) to simply leave existing classification intact, adding subspecific status where appropriate.

SEPTEMBER 23, 2012 (43 Species)
Weather: Overcast; 61F to 84F; wind WSW 0 - 1 mph.
Time: 0715 - 1025 hrs.
Area Covered: I initially walked a clockwise route around the entire lake, then a counter-clockwise route, visually covering all of the park and the fields immediately adjacent to it. Increasing numbers of Sunday visitors began arriving at 0930 hrs; several with leashed dogs. Noise from aircraft (helicopters and vintage planes) was nearly constant for the first hour of the survey, rendering the detection of bird vocalizations nearly impossible on the west side of the park near the airfield.
Birds of seasonal and/or distributional interest found today included, Greater White-fronted Goose (1 - cont.), Snow Goose (1 -cont.) Ross's Goose (1 -cont.), Great Egret (4), Common Tern (1), Anna's Hummingbird (1), Willow Flycatcher (1), Pacific Slope Flycatcher (1), Mountain Chickadee (2), and MacGillivray's Warbler (2).

SEPTEMBER 16, 2012 (53 Species)
Weather: Fair; 57F to 88F; no wind.
Time: 0703 - 1110 hrs.
Area Covered: I initially walked a clockwise route around the park (0703-0930 hrs.) , then a diagonal and counter-clockwise route (0945-1100 hrs.).
The park was relatively quiet until about 0900 hrs. when dozens of visitors arrived, several with leashed dogs. Conditions were good for identifying bird vocalizations except for occasional air traffic at the adjacent Fox Field landing strip. My initial route produced most of the bird species found today; the second circuit yielded eight additional species, primarily from the northern fence line.
Today's survey results were significantly different from those obtained two days ago (September 14, 2012: see notes below). Only six species found during the previous survey were missed today (Blue-winged Teal, Black-crowned Night Heron, Great Horned Owl, Eurasian Collared Dove, Western Wood Pewee and White-breasted Nuthatch), whereas seventeen species were added (Cooper's Hawk, Black-necked Stilt, Ring-billed Gull, Rock Pigeon, Belted Kingfisher, Pacific Slope Flycatcher, Barn Swallow, Tree Swallow, Black-throated Gray Warbler, MacGillivray's Warbler, Yellow-rumped Warbler, Common Yellowthroat, Chipping Sparrow, Lark Sparrow, Western Tanager, Brown-headed Cowbird and Lesser Goldfinch). The disparity in bird species diversity between the two morning surveys, two days apart, may be due to the combined effects of migration dynamics and a different survey schedule (e.g. today: start time: 0703 hrs. duration: 4hrs. 7 min.; previous survey: start time: 0850; duration: 2 hrs. 36 min.). These results underscore the importance of repeated surveys with similar schedules in order to achieve a reliable level of accuracy.
Birds of seasonal and/or distributional interest found today included (c.f. previous survey notes), Black-necked Stilt (6), Pacific Slope Flycatcher (1), Mountain Chickadee (1- cont.), Ruby-crowned Kinglet (1 -cont.), Yellow-rumped (Audubon's) Warbler (1), and Vesper Sparrow (4 - cont.).

SEPTEMBER 14, 2012 (41 Species)
Weather: Fair; 72F to 95F; no wind.
Time: 0850 - 1126 hrs.
Area Covered: ! walked a clockwise route around the entire park, visually surveying all areas except for the central section. About 50 park visitors and several sheriff's deputies were present during the survey; a few people had leashed dogs. Several people were feeding waterfowl near the shore. Conditions were good for identifying bird vocalizations. The northern fence line with surface water in shallow depressions, flanked by pines and tamarisk, attracted numerous warblers. Flycatchers favored the pines and tamarisk along the western fence line.
Birds of seasonal and/or distributional interest found today included, Greater White-fronted Goose (1 -cont.), Snow Goose (1 - cont.), Ross's Goose (2 -cont.), Blue-winged Teal (1), Olive-sided Flycatcher (1), Mountain Chickadee (2), White-breasted Nuthatch (1) House Wren (1), Ruby-crowned Kinglet (1), , Blue-gray Gnatcatcher (1), Brewer's Sparrow (1), Vesper Sparrow (1), and Black-headed Grosbeak (1).

Area Covered: I walked a clockwise route once around the entire park including the interior pathways. Subsequently, I returned to the southwest corner for a few minutes, to observe birds active in and around elms, pines and salt cedar. Increasing numbers of people arrived at the park by about the mid-point of my survey, including several with leashed dogs. A sheriff's patrol car was moving slowly through the eastern half of the park. Conditions were fair for identifying bird vocalizations, deteriorating by 0930 hrs. with increasing winds, air traffic, maintenance and recreational activities

Area Covered: I walked a clockwise route around the entire lake then into the central section on diagonal paths. A maintenance crew was raking along the west and northwest fence line. Relatively few fishermen were present during the survey. Windy conditions in the park probably resulted in fewer birds seen and identified than expected without wind. Sheltered areas (eastern sections) had dense swarms of aerial Diptera, attracting numerous flycatchers and warblers. I used a 10 x 42 binocular and DSLR camera for the survey.
Birds of seasonal and/or distributional interest found today included, Greater White-fronted Goose (1 -cont.), Snow Goose (1 -cont.), Ross's Goose (2 - cont.), Willow Flycatcher (4), Pacific Slope Flycatcher (1) and Yellow-headed Blackbird (1).

Area Covered: (5/7) I walked a counter-clockwise route around the entire park, then in the reverse direction to the northwest corner. Near the end of my survey I met Kris Ohlenkamp, who had just spotted an Indigo Bunting along the west fence line. This bird (a new species for the Apollo Park bird list) had been reported here yesterday by Becky and Steve Turley, and was easily refound this morning (see photo and notes below). Subsequently, another birder named Judy arrived in the park, who was also looking for the INBU. The park was quite busy with many fishermen; one was seen landing a large (ca 10 inch) trout. Swarms of airborne diptera occurred around the pines, attracting many warblers. (5/8) I walked a clockwise route once around the entire park, focusing mostly on the perimeter trees. A Palm Warbler was reported here yesterday by Jon Feenstra. Special attention was given to finding this rarity. Meanwhile, the INBU and LABU continued in the same area of the park (western fence line). Several additional species were found during this late afternoon survey, including Great Horned Owl (2), Hammond's Flycatcher, Gray Flycatcher and White-crowned Sparrow. Birds added to yesterday's list are indicated below (5/8). Most of the species I found in the park yesterday were found again today, with the exception of Western Grebe, Townsend's Warbler and Swainson's Thrush.
Birds of seasonal and/or distributional interest found today included, Greater White-fronted Goose (1 -cont.), Snow Goose (1 -cont.), Ross's Goose (2 -cont.)Ring-necked Duck (1), Dusky Flycatcher (1), Cassin's Vireo (3), Swainson's Thrush (2), Lazuli Bunting (2) and Indigo Bunting (1).

Weather: Fair; no wind; 75F.
Time: 1530 - 1705 hrs.
Area Covered: I walked a counter-clockwise route around the entire lake including part of the interior diagonal pathway on the north side. Many people, some with dogs, were in the park during my survey. A recent fire (happening sometime since my previous survey of April 19, 2012) in the field bordering the northern fence line has destroyed several acres of desert saltbush scub habitat, including two small, riparian areas where landbirds ( thrushes, sparrows, wrens, warblers, etc.) had previously come to use puddles of water for bathing and drinking. Conditions were otherwise good for finding and identifying birds. Today was the first day of the three-day Los Angeles County Audubon's "ABC" event. Apollo Park is scheduled to be closed from April 30 through May 5 for maintenance.
Birds of seasonal and/or distributional interest found today, included, Greater White-fronted Goose (1 - cont.), Snow Goose (1 -cont.) Ross's Goose (2; one relatively new arrival, see previous 2012 surveys) Common Loon, several species of warbler (e.g. Black-throated Gray, Orange-crowned, Nashville and Wilson's), Brewer's Sparrow (1) and Sage Sparrow (1). Additionally, at least three nests occupied by Black-crowned Night Heron were found.

Weather: Fair; 80F to 70F; winds WNW increasing to 20 mph.
Time: 1712 - 1850 hrs.
Area Covered: I walked a diagonal route through the park, then from the southeast lake, a counter-clockwise route around the entire park. Many people were in the park, including fishermen, joggers and dog owners. A sheriff's deputy in a patrol car stopped and asked if I was birdwatching. Except for increasing winds, conditions were good for finding and identifying birds. I used a 10x40 binocular and DSLR camera for the survey. The park is scheduled for closure April 30 - May 5.

Weather: Fair; 39F; no wind. Flooding was evident in surrounding fields, following a recent storm passing through the region a few days ago.
Time: 0837 - 1019 hrs.
Area Covered: I walked a counter-clockwise route around the entire park, surveying all habitats, including adjacent Atriplex fields. A few fishermen were around the lake, along with people walking their dogs on a leash. A LACO sheriff's cruiser was patrolling the pathways during my survey. Several sections of lawn had been recently reseeded. Conditions were excellent for identifying bird vocalizations.
Birds of seasonal and/or distributional interest found today included, Ross's Goose (continuing +1), Snow Goose (1 - cont.), Greater White-fronted Goose (1 - cont), and five species of swallow (see below).
