The suds are caused by protein. Protein is usually consumed by the nitrogen cycle and finally plant life, but if there is enough water churning by wind and white caps and breaking waves it can froth up and dry out and get blown away and get trapped a gyre where is eventually melts back down into the water. Sometimes it gets blown into a beach as you've seen. ...

I suspect this mostly is a result of need, and antipathy. First of all I think your premise that humans can't identify individual animals within a breed or species is false. People who spend significant time with animals like pet owners, farmers, and naturalists can differentiate between "their" animals and new animals much easier than people who aren't ...

When I joined the Marine Corps as a young man some 20 years ago - the first thing they did was give us a uniform and shave our heads.

Generally the national forests will have less restrictions than national parks, particularly popular ones like Yosemite. Each national forest will have its own ...

A good place to start looking for camping in the Big Sur is their hiking page. This lists their backcountry trails, some of which allow dispersed camping. Big Sur wilderness falls into two categories: Los Padres National Forest, ...

Another two reasons The first is that humans vary much more than crows do - in behavior and in color (clothing) so they are easier to tell apart. The second is that crows (and birds generally) have much more to gain from distinguishing between different humans than humans have from distinguishing crows. Humans are both a source of resources/benefits for ...

Good answers/anecdotes thus far. I find this interesting and asked an avian specialist about this. In addition to most of what has already been said (that crows have more time, necessity, and better vantage points to observe us), they emphasized a point Erik briefly touched on - their sneakiness: Crows are not easy to differentiate, even if we do watch ...
