If you attack from above you probably should have a pale ( sky coloured) belly as camophlage.

If you attack from below or low level, then you should be ground coloured.

So you would expect versatile preditors to have a boundary between a earth top surface and a sky belly.

Birds that only do one thing perhaps can be just one or other shade.

I think that great skuas must be low level attackers, Terns entirely high level attackers, and so on.

Or maybe bonzies are just thugs, and scare the hell out of their prey.

food for thought

I always liked the principle that a floating boat had twice the inertia as the mass of the boat. This can be seen as due to the mass of the boat and the mass of the water displaced by the boat. Move the boat and you are having to push around both these bodies.

Now if you go with the idea that the mass of a regular fundamental particle is not that of itself, which is thought to be zero, but the mass of the displaced higgs bosons, then one can see how mass exists.

But the Universe is expanding, and one might assume that the density of higgs bosons are therefore reducing, and there are decreasing numbers being displaced. Hence the thought that the masses are reducing as the Universe expands.

Presumably distant galazies have greater mass than close galazies. Old galazies might then be seen as having what we might think of as invisible mass. Here is a possible candidate for the misterious dark energy or dark matter.

Just a thought.

I leave the details for others to work out
