Project:
| Short name: | SELVA |
|---|---|
| Short description: | SELVA's migratory bird program includes several projects aimed at understanding stopover behavior and over-winter habitat use in Colombia.
|
| Description: |
1)Landscape use and continental movement patterns of Gray-cheeked Thrush: The duration of migration is mostly determined by the length of stopovers made between the site of origin and that of final destination. However, stopover sites are unfamiliar places full of risks for birds. This means that bird behavior at these sites is critical to detemrine whether individuals succeed on to the next stage of migration. Current technology allows to obtain both, fine-scale movement data at a local scale, as well as to follow the movements of birds across continents. We will integrate behavioral data with remote tracking to understand how birds choose between habitats in a landscape matrix, how long they spend fuelling and if this varies in individuals of different age or sex. Furthermore, we hope that the MOTUS continental alliance, through its network of radio towers, will provide precise information about the duration of migration and migratory routes of this and other species.

Five year study in shade-coffee plantations and native forest fragments aimed at understanding space use, over-winter persistence and survival and effects on subsequent migratory movements of occupying these two key Andean habitats for migratory birds.

This previously unknown role of these forests in maintaining migratory processes, highlights the need for increasing our knowledge of how birds use these areas. This need is even more critical given that tropical dry forests have lost 92% of their original cover in Colombia and are used by declining migrants such as Yellow-billed Cuckoo, Alder Flycatcher and Mourning Warbler. The deployment of Motus tags in this project will enable the estimation of key parameters of stopover behavior, such as duration, as well as describe onward migratory strategies.

This study will describe pre-migratory fueling behavior at wintering areas in Colombia and determine the length, speed and duration of onward migratory flights through the deployment of radiotransmitters.
