  1. America's Birdiest County Logistics & History LINK
    DATE: Apr 26, 2023 @ 10:20pm, 3 year(s) ago
    Hi Everyone,
    Here's additional information about the "America's Birdiest County" event that will happen
    in Los Angeles County on April 28-30, 2023.
    The count starts at midnight on Thursday night/Friday morning and ends at midnight on Sunday night/Monday morning.
    The objective is to find as many species in Los Angeles County over this three day interval as possible. We've been doing this since 2003 and regularly find more than 260 species.
    Birds can be identified by sight or sound, and as usual, rare species require documentation. All birds must be counted from land, so we can't accept anything seen on a whale watch, or from a boat on a lake, but we'd be glad to count any birds seen from Santa Catalina and San Clemente Islands or from seawatches at places such as Point Vicente and Point Dume.
    I will act as compiler again this year.
    
    Since the count in 2022, the California Bird Records Committee has accepted Nanday Parakeet and
    Red-masked Parakeet to the state list, so we can now count them. They should be straightforward to find.
    
    HISTORY
    America's Birdiest County started in 2003 in San Diego as a friendly competition among counties across the country to see how many species people could find in a single 24-hour period.
    After the first three years, the organizers changed the protocol to make it a three-day event.There were also various categories across the country to try to level the playing field so that counties in very different areas wouldn't be competing against those in other areas that have vastly more birds. Thus, counties in, say, Maine weren't competing against counties in California. Los Angeles was in the "Coastal West" category and our chief competition, at least initially, was with San Diego and Monterey. After the format changed to a three-day event, Monterey stopped competing in order to continue their traditional one-day county-wide birdathon. After 2011, the organizers discontinued the nationwide event, but selected counties continued due to strong local interest.Los Angeles and Kern Counties, which usually did very well, both continued.
    Here are the number of species found in Los Angeles County since 2003:
    Year Total
    2023 265
    2021 277
    2020 No count due to covid 19
    2019 257
    2018 263
    2017 264
    2016 270
    2015 275
    2014 272
    2013 265
    2012 262
    2011 277
    2010 271
    2009 264
    2008 255
    2007 272
    2006 265
    2005 246
    2004 240
    2003 239
    Our total jumped in 2006 due to better organization and increased interest.
    
    This event has turned into an intensive sweep of the whole county each spring and has provided a useful snapshot of the species that are present in late April. Many people who participate also record their observations in eBird, and as a result, tens of thousands of bird sightings are permanently archived, so in addition to having fun, we're also making a scientifically useful contribution.

    LOGISTICS
    Please email reports to me at lbenner@... and/or to the LA County listserve. ([email protected])
    We welcome you to send ebird lists: the easiest way is to email eBird lists to your self and then forward them to me: This makes checking for new species really easy.
    
    I will provide updates two to four times each day to track our progress and to help guide searches for species we're missing. The first update will probably happen by mid afternoon on Friday. We will also provide updates each night so that we everyone can see what we still need first thing in the morning.
    We welcome reports on the county listserve all weekend regardless of what you see: the species do not have to be rare.
    Please note that we can't count birds seen from boats, but birds seen from Santa Catalina and San Clemente Island count. Also, the Gambel's quail and chukars on San Clemente Island are self-sustaining so we can count them. Also, to continue the protocol we adopted a few years ago, we are now glad to count bald eagles seen from Santa Catalina and San Clemente Islands.
    
    ######################################
    
    NON-NATIVE SPECIES:
    Kimball Garrett asks us to please report established non-native species even if they're not the list that's accepted by the AOS or the CBRC.
    This means that we want to hear about introduced species such as parakeets and parrots, pin-tailed whydahs, orange bishops, white-eyes, Egyptian goose, Mandarin ducks, and so forth. Monitoring those populations is becoming increasingly important so please report them, and, of course, enter your sightings into eBird.
    We'll keep them in a supplemental list separate from the "regular" species.
    
    ######################################
    RARE SPECIES
    There have been a number of rare species in the county recently. Here's an abbrevicated list of some reported in the last week or so:
    Tundra Bean Goose
    Long-tailed Duck
    Yellow-crowned Night-Heron
    Broad-winged Hawk
    Blue-headed Vireo
    Pacific Wren
    Sage Thrasher
    Black-and-white Warbler
    Tennessee Warbler
    Hooded Warbler
    The Bean Goose, hawk, vireo, thrasher, and Wren would all be new if we could find them.
    This is a partial list: I haven't had time yet to go through all the rarities found in the county in the last month.
    As always, anything flagged as "rare" in eBird is going to require documentation, so please take photos, jot down notes, obtain recordings and videos, or make sketches. Please remember that your cell phone probably has an app that allows you to record sounds. They're quite sensitive and can be good for documetation.

    SPECIES PREVIOUSLY RECORDED
    Below is the list of every species we've found during previous ABC weekends.
    There are some species that we get regularly that are actually quite local and require special effort to find and/or that are just leaving or arriving at this time of year . Among them, in no particular order, are prairie falcon, American dipper, common ground-dove, Inca dove, spotted owl, northern saw-whet owl, northern pygmy owl, flammulated owl, burrowing owl, golden-crowned kinglet, LeConte's thrasher, Williamson's sapsucker, red crossbill, Swainson's hawk, common merganser, hooded merganser, summer tanager, golden eagle, and wandering tattler.
    We often struggle to find pelagic species; alcids are particularly difficult.
    
    The table below lists every species we've recorded during the ABC weekend since 2004 and the number of years in which we've found it.

    Lilac-crowned Parrot. Introduced: recently accepted by the CBRC
    Mitred Parakeet Introduced: recently accepted by the CBRC
    
    Removed: black swift and willow flycatcher because we think those reports were in error.
    If you think you see them, be prepared to provide outstanding documentation!
    
    Please start thinking of where you might be able to contribute, and we look forward to hearing from you on April 28, 29, and 30!
