    Data from: Study "NC Wood Stork Tracking"
    (2023-12-23) Schweitzer, Sara; Bryan, A. Lawrence, Jr.; Brzorad, John; Kays, Roland
    We tracked two wood storks (Mycteria americana) from a breeding site in North Carolina, documenting their migrations to southern Florida. This is one of the northernmost breeding grounds for the species. Dice was tracked with a GPS/GSM/ACC tag from e-obs GmbH, and Mr Lay was tracked with a GSM-GPS tag from Microwave Telemetry Inc. Duplicates and location outliers were flagged in Movebank by manually flagging visible outliers and then using filters. First, the duplicate filter was used to flag multiple records records with matching tag ID and timestamp, with a preference to retain "eobs:status" values in the following order: A, B, C, D, blank. Second, the speed filter was run using maximum plausible speed of 50 m/s and maximum location error 100 m, using the "longest consistent track" method.

    Data from: Tracking the migration of red-necked stint (Calidris ruficollis) reveals marathon flights and unexpected conservation challenges
    (2020-10-09) Mu, Tong; Tomkovich, Pavel S.; Loktionov, Egor Y.; Syroechkovskiy, Evgeny E.; Wilcove, David S.
    Effective conservation of migratory species depends on understanding both migratory connectivity and migration strategy. The Red‐necked Stint Calidris ruficollis is a small, highly migratory sandpiper of the East Asian‐Australasian Flyway, which is classified as Near Threatened due to ongoing population declines. We tracked the migration of three Red‐necked Stints breeding in southern Chukotka, Russia, using geolocators, and supplemented our tracking data with re‐sighting records of color‐flagged individuals. The three birds, all of which bred within 2km of each other, wintered in three different localities spanning nearly 5,000km. One individual completed its northward migration of >9400 km in two marathon flights; the second leg of that journey was completed in a nonstop flight of 5,350 km. The successful conservation of just this one population requires protection of wintering sites across a vast area, coupled with key staging sites along the flyway. We suggest that other migratory species may pose similar conservation challenges.
