Avian migration is a spectacular phenomenon, representing the annual movements of billions of birds globally. Because the greatest diversity and numbers of birds migrate at night, opportunities to observe active migration are rare. At a number of localities in North America, however, observers can quantify movements of many typically nocturnal migrants during daylight where they continue after dawn. Such locations have provided much information about species-specific phenology, status, and orientation during migration. Localities where morning flights of land birds can be observed are unevenly distributed, however, and are little reported along the Pacific coast. Here we describe a novel location for the observation of spectacular morning flights of nocturnal migrants during spring migration at Bear Divide, in the western San Gabriel Mountains, Los Angeles County, California. In two years of informal surveys at the site, we have recorded at least one morning with an estimated ~13,500 individual birds passing. Our preliminary analyses suggest that the peak of a species’ migration at Bear Divide is correlated with the latitude of a species’ breeding, being later in the spring as that latitude increases. Our data from Bear Divide provide an independent perspective on migration as quantified by local radar. Further work at this locality may help inform our knowledge of migration phenology and population trends.

Governmental studies looking toward the reorganization of present political and administrative arrangements by Los Angeles county and Los Angeles city, respectively, have been a feature of recent months in the metropolitan region of the Pacific Southwest. Three separate reports have been prepared, two of which are before the public. Certain areas of substantial agreement in principle are found in these two reports, and it now appears that by joint agreement some far-reaching changes will be proposed as charter amendments to the Los Angeles county charter. The most significant of these proposals look toward simplification of structural arrangements through reorganization of existing governmental agencies in the county and the establishment of certain centralized agencies of county-wide administration responsible for minimum standards of service throughout the entire area and available for additional service to those local communities which through their local councils order and pay for it. Likewise, the reports agree in recommending the establishment of the county-manager form of administrative organization.

Los Angeles County has a number of watercourses which discharge into the Pacific Ocean. Three of these are of major importance in that they traverse the Coastal Plain area of the County. These three are the Los Angeles River, the San Gabriel River, and Ballona Creek. They have a combined drainage area of approximately 1,645 square miles, most of which is within Los Angeles County. Such area not only comprises over 40 percent of the land area of the County but, more important, includes within its boundaries, the great majority of the County's population. The Coastal Plain area of Los Angeles County, prior to installation of flood control works, was probably subject to a greater potential flood hazard than any area of similar size and density of population in the United States. It has been subjected periodically to floods that, descending from the San Gabriel and Santa Monica Mountains, have rushed across the valley floor towards the Pacific Ocean altering topographic features and causing loss of life and property.

In 1916, Cornelius Birket Johnson, a Los Angeles fruit farmer, killed the last known grizzly bear in Southern California and the second-to last confirmed grizzly bear in the entire state of California. Johnson was neither a sportsman nor a glory hound; he simply hunted down the animal that had been trampling through his orchard for three nights in a row, feasting on his grape harvest and leaving big enough tracks to make him worry for the safety of his wife and two young daughters. That Johnson’s quarry was a grizzly bear made his pastoral life in Big Tujunga Canyon suddenly very complicated. It also precipitated a quagmire involving a violent Scottish taxidermist, a noted California zoologist, Los Angeles museum administrators, and the pioneering mammalogist and Smithsonian curator Clinton Hart Merriam. As Frank S. Daggett, the founding director of the Los Angeles County Museum of History, Science and Art, wrote in the midst of the controversy: “I do not recollect ever meeting a case where scientists, crooks, and laymen were so inextricably mingled.” The extermination of a species, it turned out, could bring out the worst in people.

In the late 1950s and early 1960s, during the height of protests and actions by civil rights activists around de facto school segregation in the Los Angeles area, the residents of a group of small cities just southeast of the City of Los Angeles fought to break away from the Los Angeles City Schools and create a new, independent school district—one that would help preserve racially segregated schools in the area. The “Four Cities” coalition was comprised of residents of the majority white, working-class cities of Vernon, Maywood, Huntington Park, and Bell—all of which had joined the Los Angeles City Schools in the 1920s and 1930s rather than continue to operate local districts. The coalition later expanded to include residents of the cities of South Gate, Cudahy, and some unincorporated areas of Los Angeles County, although Vernon was eventually excluded. The Four Cities coalition petitioned for the new district in response to a planned merger of the Los Angeles City Schools—until this time comprised of separate elementary and high school districts—into the Los Angeles Unified School District (LAUSD). The coalition's strategy was to utilize a provision of the district unification process that allowed citizens to petition for reconfiguration or redrawing of boundaries. Unification was encouraged by the California State Board of Education and legislature in order to combine the administrative functions of separate primary and secondary school districts—the dominant model up to this time—to better serve the state's rapidly growing population of children and their educational needs, and was being deliberated in communities across the state and throughout Los Angeles County. The debates at the time over school district unification in the Greater Los Angeles area, like the one over the Four Cities proposal, were inextricably tied to larger issues, such as taxation, control of community institutions, the size and role of state and county government, and racial segregation. At the same time that civil rights activists in the area and the state government alike were articulating a vision of public schools that was more inclusive and demanded larger-scale, consolidated administration, the unification process reveals an often-overlooked grassroots activism among residents of the majority white, working-class cities surrounding Los Angeles that put forward a vision of exclusionary, smaller-scale school districts based on notions of local control and what they termed “community identity.”
