Migratory routing and departure decisions of <em>Porzana carolina</em> (Sora): New insights from the Motus Wildlife Tracking System
收藏资源简介：
During migration, birds make a variety of decisions that may impact their overall survival and fitness. These decisions include, but are not limited to, their overall migration route as well as their departure timing, considering variable weather conditions. Understanding how birds make these decisions can provide insight into not only their general migration strategy but also the constraints they face on migration. Unfortunately, the migratory ecology of many members of the Rallidae family remains poorly documented, leaving a critical gap in the migration literature. From 2017 to 2022, we fitted 202 Soras (Porzana carolina) with transmitters at Jug Bay, a critical stopover site along the Patuxent River, Maryland, USA, and tracked their migratory movements and decisions using the Motus Wildlife Tracking System. Tracking data revealed a tendency to follow the Atlantic coast in the fall. Spring migrants took variable paths, with routes primarily to the Great Lakes region, but al..., , # Data from: Migratory routing and departure decisions of *Porzana carolina* (Sora): New insights from the Motus Wildlife Tracking System Dataset DOI: [10.5061/dryad.msbcc2g9k](10.5061/dryad.msbcc2g9k) ## Description of the data and file structure This dataset investigates the departure routes and decisions of Sora (*Porzana carolina*) during their fall and spring migrations. Birds were trapped using modified Seth-Lowe Clover Leaf traps along the Patuxent River in Maryland from 2017-2022. Sora were fitted with Lotek nano tags and tracked via the Motus Wildlife Tracking System. We examine the atmospheric conditions that inform the departure decisions of these birds, as well as detail some of the most commonly used migratory pathways. ### Files and variables #### File: SORA-tag-detections-raw-rm-dep.rds **Description:** Raw, uncleaned detection data across the Motus Network of Soras tagged at Patuxent River Park.
