As an addition to my last post regarding Flycatchers During Migration, another small bird to keep a watch for during the autumn migration in Portugal is the Garden Warbler. It’s not a resident and can only be spotted as it passes through during migration. The Garden Warbler has no real features to identify it, therefore, if you spot an “LBJ” (Little Brown Job, the term given to many small birds difficult to ID) during the migration period then it maybe a Garden Warbler. They are quite shy and like to keep in the cover of branches so spotting them is quite difficult.
