Actually, I saw both the male and female at the nest during a full hour observing the nest. This watercolor is a composite of the desert plants. Cactus wrens nest in Cholla but surrounding all this are the imposing Saguaro.
What makes us see a bird and see a nest? It takes time to follow the flight pattern, and awareness. The nest was the same color as the birds and the Cholla!
I will teach the art of SUMI-E brush painting at Pt Reyes(.org)
To know nature is through painting esthetic values (in black inks):
WABI (subtle taste)
SABI (elegant simplicity)
Color adds joy!
