More signs of Spring

I'm still waiting for a day when it is warm enough to inspect my bees properly. However the signs are that Spring is on its way. The Primroses are in full flower...

...and the Black Alder trees are loaded with pollen. The following photo clearly shows the male and female catkins on the end of a twig.

Hopefully one day soon the temperature will creep up into the mid to high teens and I'll be able to have a look inside the hives and see if my colonies are building up as they should be at this time of year.
