Tracking Radar Station

Caption

Nilsson et al. measured with a tracking radar over three years the speed by which birds flew over Falsterbo Peninsula, a bird migratory hot spot in south-western Sweden.

Passerine birds, also known as perching birds, that migrate by night tend to fly faster in spring than they do in autumn to reach their destinations.
