Bird tracks

Observation - Bird tracks - UK and Ireland. Description: I know that the vertical tracks are a bird - blackbird probably - but the horizontal tracks are different. No scale unfortunately, but I remember thinking the vertical tracks looked spot on for blackbird, so that gives a very rough idea of scale.
