One month I'm studiously keeping track of each new sign (daffodils, crocuses, primroses), the next it seems that everything comes at once (willow leaves, nettles, oak leaves, wildflowers, migrant birds, lambs, calves, plenty of wild food). The transition into the abundance of early summer is less noticeable at the time, though on reflection the visual cues are there in Lake Field and in the trees and farmland beyond.
