Both species were mist‐netted regularly during autumn and spring migration on Mauritania and the migration phenology of the species in the western Sahara is described here for the first time. Autumn migration of Western Olivaceous Warblers through central Mauritania lasts from early August to early October. Passage at the coast started later and occurred during a shorter time period. The species does not seem to winter in central Mauritania. During spring migration, Western Olivaceous Warblers occurred from early March to early May. No birds were mist‐netted in spring at the coast although some were present. The Eastern Olivaceous Warblerwas mist‐netted at the inland sites only. Only a few birds were mist‐netted on autumn migration, which was between late... |
