Still 30 March 2014, in the botanical garden of Heredia in Costa Rica. Not just birds in that garden; art as well. This art, based on the woodcut print Metamorphosis III by Dutch artist M.C. Escher, was in one of the garden buildings; a round gazebo.
In Escher’s work, reptile forms slowly morph into other forms.
And bees morph into other insects.
And birds into fish.
And birds into mammals.
Until we were back at the reptiles again.
