A day in the life of a Turnstone

So nice to get a bit of sunshine! Last night was freezing! I was just thinking, how long is it til we fly back to Greenland? Forget it! You are not even the right colour. Remember what we look like in our summer outfits? Oh yes, long time yet. I know. I just like to…

The piles of seaweed were gradually pushed up the beach by the incoming tides, eventually accumulating beyond the strand-line, where it slowly decays and eventually dries out. This gift from the sea is a wonderful bounty which is…

Iridescence in insects

The iridescent wings of Morpho butterflies are some of the best examples. The spectral reflectance changes with the angle of incidence – i.e. the viewing angle…
