A spring-like day

Meteorological spring begins officially on Sunday 1st March. As if to herald that auspicious day, Wednesday was sunny and mild. We opened the patio doors to our sitting room to listen to frenetic birds singing loudly, claiming their territory, challenging their peers.
Squirrels cavorted in the trees, chasing madly up and down the tree trunks, leaping from pathway to pathway along the naked oak tree branches.
The first butterflies were flitting about the shrubs. A bright flash and flittering of lemon yellow, the Brimstone butterflies (Gonepteryx rhamni) had emerged from their winter hibernation in the ivy or holly or brambles. It is the males that are so gaily decked out. The mates they hope to impress are more soberly dressed in greenish-white. They are long-lived, these harbingers of spring, enjoying a full twelve-month of life. They survive almost freezing temperatures with glycerin, a natural ‘anti-freeze,’ and by controlling the water in their bodies. While the warmth of a February sun tempts them from their lairs, a sudden drop in temperature can send them back to shelter.
It’s good
to be alive!
