Unusual bird sightings: migration

It’s the time of year for unusual sightings in unexpected places. Recent observations recorded on Ornitho.cat include 28 Booted Eagles heading northwest and 2 Ospreys southwest, seen by an observer on a roof in the middle of Barcelona. In Sallent a goshawk was seen eating a mallard and a Black Stork was wheeling over Tordera.  And someone snapped this Griffon vulture on a structure over a busy road near Montserrat.
