Common birds can be engaging subjects. While looking for some Sandhill Cranes in a winter farm field, I came across these Canada Geese.

European starlings were introduced to North America allegedly by 19th Century Shakespeare fans, since the birds were mentioned in his work. One of nature's amazing sights is a starling murmuration. If you've never seen a flock morphing into amazing shapes as it flies, google the term, sit back, and be amazed.

Red Wing Blackbirds also gather in huge flocks and create murmurations. You can find another image from this flock in National Geographic's Backyard Guide to Birds of North America. It is quite exciting to get a call from NG asking to purchase rights to a couple of your photos!
