Mesmerizing Migration Map: Which Species Is Which?

January 20, 2016

If you enjoyed our animated map of bird migration but wondered which species is which—here’s help. This is the same animation but each species is represented by a number—so you can find the name of any migrant that catches your eye by looking it up in the list below.

It’s a crowded map so we apologize that some numbers will be hard to read and follow—but we still enjoy watching species like Bobolink (#20), Solitary Sandpiper (#88), Prothonotary Warbler (#76), Lazuli Bunting (#55), Purple Sandpiper (#78) and Yellow-bellied Sapsucker (#114) to name a few. Browse through the numbers and let us know which migrant’s route is your favorite.

  • Arturo Velez

    GREAT work! Congrats!

  • Aunt Lili

    Can we get some under-grad to separate all the animations by number… Migration up the Mississippi gets a little jumbled there – difficult to discern… but now i’m acting spoiled! :D

  • Arturo Velez

    Me too! I’d like to know what percentage of these mnigratory birds breed in Mexico. THX!

  • JordanLanham

    Yes! Wonderful work, though the ability for users to click on each specific bird and view its route would be excellent.

  • JordanLanham

    Yes! Wonderful work, and the ability for users to click on each specific bird and view its route would be excellent.

  • Sunce More

    this is great:)

  • Jeanne Brooks

    Fantastic!! Thank you!

  • wil

    Or add the ability to select one number and have it turn red. But really, this is wonderful as is.

  • KarenL

    Wow! Those sandpipers are pretty impressive!

  • Mariann Davis

    waaaah no redknot.

  • Bob AZ

    Wonderful! But it would be terrific if we could click on an individual specie (say 106) in the legend to make it red instead of black.

  • Felipe Mercado

    No bird migration in Brazil? or Cornell Lab didn’t include bird species from that area?

  • TraveLAr

    No pelicans, ibis, egret, spoonbill, heron… maybe they don’t migrate as much as I thought.

  • Ken White

    Brilliant achievement. Phenology for everyone to see.

  • Ken White

    I’m waiting for the hawks !

  • Zoë C. Smith

    Marvelous, this will help my class of Audubon Adventurers understand bird migration a bit more easily!

  • Paulo Krieser

    This is a great job. Congratulations!

  • Paulo Krieser

    Hi Felipe. I´ve found the Batuiruçu #3, acc to Wikiaves it appears in whole Brazil, altough it´s average place in this migration map is in west south of Brazil.

  • Paulo Krieser

    I´ve found also Andorinha do Campo # 21 and Guaracava de bico curto # 86

  • Brett A. Lawrence

    So no one want’s to be a white-rumped Sandpiper (106), ever! And hey, Gray-crowned Rosy-Finch (46), what’s the point?

  • arielarosaberg

    I wish they would have do several maps with less numbers to be able to identify the species much better. It is a good start anyway…

  • edwardabraham

    Any chance you could make the data available? Would be really great to see the different visualisations of this data that people could come up with.

  • douqep

    Great stuff. I think the easiest improvement would be to allow a zoom. That would allow for more regional views and make it easier to see the numbers. Great stuff, thanks.

  • Claudia M Thomas

    Wow – that white-rumpled sandpiper covers a lot of territory, and really alters its route between its two trips! And that purple martin just can’t wait to get back home. Thanks for a fabulous map!

  • Christopher Fisher

    Great work and fascinating to watch. Of course it immediately makes us want more detailed info. The ability to stop the map and move forward day by day would be great and perhaps not to difficult technically. It would also be great to have a “show/hide” checkbox next to each species so you could select any set of species to follow.

  • Leanne Mentz

    Who knew how fast sandpipers migrate!

  • Laurie Ardis

    It looks like the eastern seaboard is under-represented. Maybe us easties should up our siting reports.

  • Jude

    Wonderful to see where our friends go and return ! Hope there will be map for raptors, especially ospreys, soon. Thanks for this exciting project !

  • Bawa

    Why only 2 species migrating through California? Surely we get a lot more than that.

  • brent1023

    The pine warbler animation does not animate in my browser.
    Great information. A species at a time would be even better.

  • Peggy Randall

    Very few migratory birds in California or even flying over California. Maybe birds there just don’t need to migrate??

  • Sandy Budz-Wilson

    We live in east-central Saskatchewan and this year around 6-8 robins showed up on Feb. 2nd. Never never are they this early.

  • Rick MIC

    This morning I saw two Robins chasing each other in what appeared to be a mating ritual. I live in north suburban Detroit, MI.

  • no hawks?

  • M Webb

    Amazing and good to anticipate!

  • NameSanitizedForYourProtection

    I’ve seen Robins pretty much all winter in Grand Rapids. Had two Eastern Bluebirds on the suet feeder yesterday.

  • Mary J. Berry

    We already have Hawks in the Niagara region, arrived early in February and stalking the bird feeders!

  • dgcasey0325

    And who knew that the movie The Big Year got that one thing right, about the American Golden Plover. It flies from Rio to Northern Alaska. Those and the sandpipers are crazy. :)

  • dgcasey0325

    I don’t know, maybe they want to stay as far away from Cal as I do. ;)
