If you're a birder, you'll know what a life list is. It's basically a list of all the bird species one has observed and positively ID'd in one's lifetime. This blog is a record of my "critter" life list (mostly of birds), including photos I've taken over the years, some of the actual lifer if I was lucky enough to get the shot. Don't expect National Geographic quality stuff here, just the work of an amateur photog who loves to trudge out into nature.

LIFE LIST DATE? Don't remember, lol!

From Wikipedia:
The American crow (Corvus brachyrhynchos) is a large passerine bird species of the family Corvidae. It is a common bird found throughout much of North America. American crows are the new world counterpart to the carrion crow and the hooded crow. Although the American crow and the hooded crow are very similar in size, structure and behavior, their calls are different. The American crow nevertheless occupies the same role the hooded crow does in Eurasia.
From beak to tail, an American crow measures 40–50 cm (16–20 in), almost half of which is tail. Mass varies from about 300 to 600 g (11 to 21 oz). Males tend to be larger than females. The most usual call is CaaW!-CaaW!-CaaW!.
The American crow is all black, with iridescent feathers. It looks much like other all-black corvids. They can be distinguished from the common raven (C. corax) because American crows are smaller and from the fish crow (C. ossifragus) because American crows do not hunch and fluff their throat feathers when they call.
American crows are common, widespread, and susceptible to the West Nile virus, making them useful as a bioindicator to track the virus's spread. Direct transmission of the virus from American crows to humans is unheard of and unlikely.
