In many bird species, the male is much more colourful than the female:
Belted Kingfishers are different. The female has a rusty patch on the side which the male does not.
I photographed a female coping with a large fish this morning at Col. Sam Smith Park:
this is the garden: colours come and go,
frail azures fluttering from night’s outer wing
strong silent greens serenely lingering,
absolute lights like baths of golden snow. – e. e. cummings (1894–1962)
