Dearest Angel, they are a lot bigger than a Canary, they a bit smaller than a crow. Have you studied what decides the colours Angel, does any one know ?
i always think about it. There must be some clue in the theory of natural selection. The colurs must have some function, some meaning.
Why crows are black ? Please tell me if you know Angel
lots of love and hugs

All I know about "color sellection" is that the male of the given species is usually the one with the most colour - to attract the famale!
We humans have all backwards.
Some of the color apparently also happens (obviously/you know this too) to make them more or less visible according to environment, preditors, etc.
I guess is somewhat radom - if there is such thing - from our perspective/present knowledge?
Why do we have/had (?) four races?
And then, colour variations among them? HM!?

Hi Angel, yes i'll do one post on how you can't spot river tern chicks sitting on a rock, they merge with the background, they look completely different from their parents. This is to fool the predators.
Attracting a female is big business Angel Amount of money people spend on perfumes clothes, there are some funny commercials too. A bride during a wedding ceremony leaves her husband and goes after a guy wearing some brand of perfume or deodorant.
love and Hugs
The yellow stands out so strongly with the black. Birds are fascinating: so quick, so watchful and careful.
