Nancy Merrill Photography has a Photo a Week challenge and this week’s theme is “nature’s white.”

All of the following were taken from Feb. 6 to Feb. 10 in the Ngorongoro Conservation Area of northern Tanzania.

Kori bustard male displaying his “whites”!

Zebras are half white…
…and many birds are mostly white, like this yellow-billed stork,…
…cattle egrets,…
…the sacred ibis…

and the secretary bird.

There are white flowers, like cycnium…

and scorpion flower.

White mushrooms are somewhat universal; this one was growing on the southern Serengeti plain.

All the photos except the last one were taken with a Sony A380. The mushroom was taken with a Samsung Galaxy 7.
