I was flooded with answers to yesterday’s blog quiz from the entry “A Journey to a World of Birds.” Congratulations to Sofia Isabella, Jonathan P., and Tommy V.,our three winners who first correctly answered the question. This was a case of the early bird catching the worm, because within an hour of posting the question the responses began to pour in and have continued up to today.(Stay tuned to Doug’s Blog for more contests coming soon.)

And now the answer: I shot these images from the Ballestas Islands off the coast of Peru, and the highly prized cash crop is guano. (If you have not done so, click on each of the images for a higher resolution image with more details.)
