Bird Density and Marine Mammal Counts Based on 7700 Meter Bins in Southern California, 1999-2002 Tracklines and associated observations were mapped and analyzed using ArcMap (ESRI, Redlands, CA). GPS data were recorded in NAD27 map datum and projected to an USGS Albers Equal Area Conic map projection for presentation and subsequent density analyses. Concatenated GPS and observation data were then used to generate point and line coverages in ArcMap (ESRI, Redlands, CA). We designed a custom analytic tool using ArcMap Model Builder that allows for the construction and export of user-specified and effort-adjusted spatial binning of species observations along continuous trackines. For the purposes of this report, we calculated seabird density estimates and marine mammal counts along continuous 3.0-kilometer and...

Since 1981, HALE has maintained a network of live-traps to control invasive mammalian predators and protect these endangered birds. To continue evaluations of trapping efficiency in HALE, we analyzed 2000 - 2014 trap events. Trap events were divided up into six event types classified into three event categories: no event, other event [bait lost, or trap triggered], or predator event [rat, cat, or mongoose caught]. Event type analysis was divided up...

Over the past decade, domoic acid (DA) and saxitoxin (STX) have been increasingly problematic bicoastally in the United States. We investigated pooled seabird mortality data from opportunistic sampling events between 2007-2018, across three states, to examine the patterns and role of DA and STX in seabird mortality events from the continental United States. Patterns in DA and STX levels and affected tissue type were reviewed, and two specific accounts of localized and pervasive event types were examined. There has been increased toxin detection with expanded tissue testing during...

M12PG00014). This study focuses on obtaining information about populations of Brown Pelican (Pelecanus occidentalis carolinensis) across the northern Gulf of Mexico. Study objectives are to (1) document dispersal, seasonal and annual movements, seasonal home range, and site fidelity of marked adult Brown Pelicans among nesting colonies from the Gulf coast, (2) compare contaminant exposure risk, contaminant levels, and health parameters in adult and nestling Brown Pelicans from various colony sites, and (3) document the relationship of local environmental, nest site characteristics and...

Surveys were flown at 60 meters (200 feet) above sea level at 160 kilometers per hour (90 knots) ground speed. The surveys were flown in a high-winged, twin engine Partenavia PN 68 Observer aircraft following methods developed for seabirds by Briggs et al. (1987). GPS points were recorded every five seconds to allow adequate spatial coverage of the trackline (222 meters is traversed every five seconds at the survey speed of 160 kilometers per hour) and to limit the size of the resulting data files. Data was collected using a laptop computer running the program dLOG (R.G. Ford Consulting, Inc.) that allowed...

Aerial survey methods follow Mason et al. (2007). Specifically, we recorded all sightings of marine animals, vessels, and floating objects from twin-engine, high wing aircraft (Partenavia P-68s, Aspen Helicopters, Oxnard, CA, or California Department of Fish and Game) along pre-determined 100-meter (50 meters per side) strip transects at 60 meters above sea level.

More than 14,000 dead seabirds were reported and a total of 117 carcasses were examined. 92 cases had emaciation identified as the Cause Of Death (COD), seven cases where COD was undetermined, and 17 cases where COD was determined as "Other", which included predation, trauma, encephalitis, peritonitis, and bacterial infection. Low Pathogenic Avian Influenza (n=4) and saxitoxin (n=15) were also detected; however, the virus and biotoxin were not determined to be the COD except for one case in 2020 where saxitoxin toxicosis was suspected.
