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. ...

No, gulls (of some species at least) steal food from other birds by moving them until they drop it. They must then be adept at snatching the falling food in mid air. There's material of interest in the Wikipedia article on seabirds - search for kleptoparasitism, reference 23 looks particularly interesting. The article on mobbing also hints in this ...

For practical purposes, rarity is beyond difficult to answer. Sure there may be a biological survey buried somewhere in some journal, but specific topics like that don't get much traction outside of small specialized communities of biologists. For a heuristic, I have used a combination of google images and pricing. For google images there are certainly ...

This is really just a hypothesis, but here in the UK we also get mixed wader flocks. A significant reason for large/mixed flocks to occur is predation. Watch out for what happens when a large flock of waders (almost by definition very exposed on the ground) spots a falcon. They scatter in every direction, not maintaining a straight line for any time at all. ...

What your describing is flocking. It's an extremely complex behaviour where individuals react to their immediate neighbours giving the sense that the whole flock moves as a whole. Birds naturally flock (in the air or on the ground) as a defensive mechanism against predators, etc. Though complex there appears to be some basic rules to the mechanism as a whole:...

Sea foam, ocean foam, beach foam, or spume is a type of foam created by the agitation of seawater, particularly when it contains higher concentrations of dissolved organic matter (including proteins, lignins, and lipids) derived from sources such as the offshore breakdown of algal blooms or human waste. The lack of wildlife could be explained by their food ...

This really depends on what your situation is. You want to fish from the shore, so how bad is the surf? The bigger the waves, the larger the weight. Also, you could use lead like this. The "arms" help the lead to dig into the sand, and then turn over once you put some pressure on them and reel it in. This way, since fish hook themself once they take the ...

You're right that the various species of shorebirds, including in your area, like most of the same types of foods. The diet is primarily comprised of invertebrates such as crustaceans, worms, mollusks, and insects. Although some species are indeed bigger, they tend to co-exist peacefully. One reason is that they have different types of bodies and bills, ...

By lifting one leg into their down, they are conserving heat.

I think a reasonable guess would be jellyfish larvae, also known as "sea lice." Sea lice are actually the microscopic larvae of jellyfish and other ocean stingers which contain the same nematocysts (stinging cells) as mommy and daddy. (They) are probably the most commonly encountered stinging threat to divers and swimmers at the beach. There's a ...

"hanging out" together happens because different species eat the same food, require the same nesting areas, migrate in the same flyways, etc. Many species compete/become territorial for nesting areas, but less so for food sources.
