February and March can produce some beautiful days; low sun throwing sharp shadows, clear air and bright blue skies. But if like me you only have a limited number of birding opportunities during the year, then its important not to be seduced by the weather and waste them on barren late-winter days. The local bird web sites are full of visit lists with small numbers and nothing of note. In just a few weeks the spring migrants will be here en-masse. So its time to sit tight, do those household chores, and wait.
I did sneak out to SLRS to see it fuller than I've ever seen. There were 8+ Shovelers and Gadwall in the teens, and a trip to the local supermarket was livened up by a flock of Fieldfares going over, but a cycle trip with D#1 round Hatfield Forest was practically bird-free.
