Migratory bird populations are declining rapidly due to the loss and degradation of habitats they use throughout their life cycle. To stop this decline, we need to understand habitat use and movement at multiple spatial scales, from continental to local. Motus station detections throughout a species range can tell us about the extent and timing of movements at continental scales and within their breeding habitat. Using Motus-compatible radio tags, we tracked Western Yellow-billed Cuckoos, a cryptic declining species, at continental and local scales. At the continental scale, detections from Motus stations have provided insights into migration routes and timing during spring and fall. Within the breeding grounds, a network of telemetry nodes (small Motus receivers) enabled triangulation of tag locations to estimate movement distances and timing, as well as home range size. Additionally, placing nodes close to nests has allowed us to quantify time budgets and transitions between nesting stages, which were validated through hand-tracking. This multi-scale framework offers a comprehensive view of habitat use and movement patterns. We discuss our findings tracking Cuckoos tagged in the Kern River Valley, CA, and how these methods can be applied to other cryptic bird species to enhance conservation strategies. | |||
