Differential migratory strategy in Reed warbler sub-species

|June 2017 in the Natural Reserve of Estagnol pond|

Since 2016, Frédéric Jiguet and several collaborators describe the Iberian & North African Reed Warbler as a subspecies, Acrocephalus scirpaceus ambiguus (Olsson et al. 2016 Mol Phylogenet Evol 102: 30-44). Now we extend this work and we try to observe a potential differential migration strategy between the nominate subspecies (scirpaceus) and the ambigus.

With Benjamin Vollot and Pierrick Devoucoux we caught 20 Reed Warbler (A. s. scirpaceus) in two days in the reed bed of the Natural Reserve of Estagnol pond (close to Montpellier, France). On each bird, we fitted a geolocator (0.3g Migrate Technology) on its back.

In the same time, José Luis Copete in Spain put 10 geolocators on Seed Warbler of the ambigus subspecies.

As in each case with the geolocators technology, now we have to wait a year before hope to recapture some of these birds. So exciting again !!!
