The United States population of California Sea Lions (Zalophus californianus) range from southeast Alaska to the Pacific coast of central Mexico. While this population does not breed in Canada, some sub-adult and adult males migrate northwards to British Columbia during the non-breeding season with an arrival in August-October and a departure in April-May. The population in coastal BC has not been fully assessed since 1985. However, opportunistic counts suggest that California Sea Lions overwintering in BC increased in abundance from approximately 1,000 animals in the mid-2000s to several thousand individuals in more recent years. The survey targeted Steller sea lions and sites were chosen based on knowledge of historically occupied rookeries and haul-out sites with nearby areas monitored for potential shifts in distribution. The presence of California Sea Lions are based on incidental observations while surveying sites for Steller sea lion counts. This dataset contains counts that have been collected from sightings of individuals in the 2016/2017 survey season.

Band-tailed Pigeons (Patagioenas fasciata) are Californias only native wild pigeon. The birds in California are part of the Pacific Coast population (P. f. monilis), and inhabit montane coniferous forests and oak woodlands in the Coast Ranges and western Sierra Nevada (Keppie and Braun 2000). Though some populations appear to be resident, the species is generally considered migratory (Smith 1968). Breeding occurs in the coniferous forests of California, Oregon and Washington (Blackmon 1976; Keppie and Braun 2000; Smith 1968). These birds are characterized by slate gray to purple plumage with males having a deeper purple coloration. There is a bright white crescent on the hindneck of adults with a patch of greenish bronze iridescent patch below (Keppie and Braun 2000). A k-selected species, Band-tailed Pigeons have the lowest reproductive potential of any game bird in California (Grinnell 1913). Breeding peaks in May/ June and extends through the summer, with usually not more than 1 nesting attempt per season and a typical clutch size of 1 egg, though larger numbers of nesting attempts and eggs per clutch have been reported (Keppie and Braun 2000; Leonard 1998). Feeding is variable and dependent on fruit/mast availability. During the non-breeding season, birds are nomadic and localize to acorn masting events. Birds have been documented feeding on fresh buds in spring then moving into elderberries, cascara, madrone and other fruits. In fall and into winter, acorns are taken whole (Keppie and Braun 2000). Pacific Coast Band-tailed pigeons continue to experience long term population declines. Harvest independent population monitoring comes from the Breeding Bird Survey and the Mineral Site Survey. The Breeding Bird Survey provides evidence of a significant downward population trend of 2.0% per year over a term from 1968-2012. Mineral Site Survey results show downward trends but 9 and 5 year trend confidence intervals include zero and are therefore considered inconclusive (Sanders 2012). The Mineral Site Survey is coordinated by the USFWS and is a cooperative effort amongst California, Oregon, Washington and British Columbia (via the Canadian Wildlife Service). The survey takes advantage of the birds habit of congregating at springs and seeps that have high levels of mineral content. Fifty sites are surveyed annually; 10 in California, 22 in Oregon, 14 in Washington and 4 in British Columbia (Sanders 2012). The results of this survey are used to index the band-tailed pigeon population at the population level. These data describe the location of the 10 sites required for the flyway survey as well as additional sites that are surveyed if possible to improve precision. Coordinates of locations are available and may be distributed upon request and written justification of need.

Bumble bees (Bombus) are vitally important pollinators of wild plants and agricultural crops worldwide. Fragmentary observations, however, have suggested population declines in several North American species. Despite rising concern over these observations in the United States, highlighted in a recent National Academy of Sciences report, a national assessment of the geographic scope and possible causal factors of bumble bee decline is lacking. Here, we report results of a 3-y interdisciplinary study of changing distributions, population genetic structure, and levels of pathogen infection in bumble bee populations across the United States. We compare current and historical distributions of eight species, compiling a database of >73,000 museum records for comparison with data from intensive nationwide surveys of >16,000 specimens. We show that the relative abundances of four species have declined by up to 96% and that their surveyed geographic ranges have contracted by 23–87%, some within the last 20 y. We also show that declining populations have significantly higher infection levels of the microsporidian pathogen Nosema bombi and lower genetic diversity compared with co-occurring populations of the stable (nondeclining) species. Higher pathogen prevalence and reduced genetic diversity are, thus, realistic predictors of these alarming patterns of decline in North America, although cause and effect remain uncertain. Bumble bees (Bombus) are integral wild pollinators within native plant communities throughout temperate ecosystems, and recent domestication has boosted their economic importance in crop pollination to a level surpassed only by the honey bee. Their robust size, long tongues, and buzz-pollination behavior (high-frequency buzzing to release pollen from flowers) significantly increase the efficiency of pollen transfer in multibillion dollar crops such as tomatoes and berries. Disturbing reports of bumble bee population declines in Europe have recently spilled over into North America, fueling environmental and economic concerns of global decline. However, the evidence for large-scale range reductions across North America is lacking. Many reports of decline are unpublished, and the few published studies are limited to independent local surveys in northern California/southern Oregon, Ontario, Canada, and Illinois. Furthermore, causal factors leading to the alleged decline of bumble bee populations in North America remain speculative. One compelling but untested hypothesis for the cause of decline in the United States entails the spread of a putatively introduced pathogen, Nosema bombi, which is an obligate intracellular microsporidian parasite found commonly in bumble bees throughout Europe but largely unstudied in North America. Pathogenic effects of N. bombi may vary depending on the host species and reproductive caste and include reductions in colony growth and individual life span and fitness. Population genetic factors could also play a role in Bombus population decline. For instance, small effective population sizes and reduced gene flow among fragmented habitats can result in losses of genetic diversity with negative consequences, and the detrimental impacts of these genetic factors can be especially intensified in bees. Population genetic studies of Bombus are rare worldwide. A single study in the United States identified lower genetic diversity and elevated genetic differentiation (FST) among Illinois populations of the putatively declining B. pensylvanicus relative to those of a codistributed stable species. Similar patterns have been observed in comparative studies of some European species, but most investigations have been geographically restricted and based on limited sampling within and among populations. Although the investigations to date have provided important information on the increasing rarity of some bumble bee species in local populations, the different survey protocols and limited geographic scope of these studies cannot fully capture the general patterns necessary to evaluate the underlying processes or overall gravity of declines. Furthermore, valid tests of the N. bombi hypothesis and its risk to populations across North America call for data on its geographic distribution and infection prevalence among species. Likewise, testing the general importance of population genetic factors in bumble bee decline requires genetic comparisons derived from sampling of multiple stable and declining populations on a large geographic scale. From such range-wide comparisons, we provide incontrovertible evidence that multiple Bombus species have experienced sharp population declines at the national level. We also show that declining populations are associated with both high N. bombi infection levels and low genetic diversity. This data was used in the paper "Patterns of widespread decline in North American bumble bees" published in the Proceedings of the National Academy of United States of America.

This dataset includes all North American Breeding Bird Survey data collected in Mexico between 2008-2018. These data were used as the basis for all analyses discussed in an associated publication: The North American Breeding Bird Survey in Mexico, 2008-2018 — A Status Report; https:doi.org/10.3133/cir1479. The records include avian point count data for all reported taxa (species, races, and unidentified species groupings). In addition to avian count data, this dataset also contains survey date, survey start and end times, start and end weather conditions, a unique observer identification number, route identification information, and route location information including country, state, and BCR, as well as geographic coordinates of each route's start location. These data were collected annually during the breeding season, primarily in May, June and July, along randomly established roadside survey routes in seven states in northern Mexico (Baja California Sur, Baja California, Sonora, Chihuahua, Coahuila, Nuevo León and Tamaulipas). Routes are roughly 24.5 miles (39.2 km) long with counting locations placed at approximately half-mile (800-m) intervals, for a total of 50 stops. A brief summary of the methodology is as follows: At each stop a person highly skilled in avian identification conducts a 3-minute point count, recording every bird seen within a quarter-mile (400-m) radius, or heard at any distance (excluding birds believed to have been recorded at a previous stop). Surveys begin 30 minutes before local sunrise and take approximately 5 hours to complete. Routes are sampled once per year. NOTE: The data in this release include all records reported. They have not been subjected to the rigorous quality control screening that BBS data from the U.S. and Canada receive. Therefore, these data are NOT intended to be lumped with U.S. and Canada data for pooled population analyses.
