Early morning walk along the old railway

Walked 2 miles along the disused railway track near home this morning. Glorious weather, frosty and sunny.
Spotted over 20 robins singing in trees and bushes along the route and also a flock of redwings foraging in the hawthorn bushes.
Lots of hazel with 'lamb's tail' male catkins in the bank side. The tiny red female flowers are only just coming out.
The pond next to the foorpath was still frozen over at 10.00 a.m.
