"Most blue tits begin building their nest in late March. This allows them to synchronise breeding so that the hatching of their chicks coincides with peak food availability - the tiny caterpillars that have also hatched to feast on fresh tree leaves.
Records show however that some get a much earlier start, building as early as January, and that some late-comers don't get going until the end of May. It could be that in years when the emergence of tree-munching caterpillars is delayed or unseasonably early, it's an advantage to nest out of sync with the rest of the crowd"

Travelling to and from London last week, lambs in the fields, and a few calves, noticed loads of spring flowers out in the city, daffs were ahead of the Midlands by at least a couple of weeks, and something I don't see at all up here, mimosa trees in full bloom in a few sheltered spots. We have crocuses and the last of the snowdrops. The wheel of the year turns.
