Scroll left to right. So this is the whole mating ritual of the Western Grebe (well, the "dance" part anyway, they actually do some other head-bobbing behavior). This elapsed in 5 seconds as recorded by my camera. It is quite a sight to see.
Canon 20D, Canon 400mm + Canon 1.4X TC, 1/1250 shutter, f/8.0.
FYI: This is heavily compressed and downsized. This "original" you are seeing here is about 344 KB, while the true original is 787 MB and four times larger in actual size. This means that you will see some distortions within the image.
Though there is no copyright on the photo just yet, please respect this as copyrighted material as stated on my front page. Thank you.
