He argued that a predator, such as a young bird, must attack at least one insect, say a wasp, to learn that the black and yellow colours mean a stinging insect. If bees were differently coloured, the young bird would have to attack one of them also.
Colorpoint patterns are where the extremities (paws, face, ears and tail) of the animal are colored differently to the rest of the body.

[ 123 ] Pigs often begin life in a farrowing or gestation crate , which is a small pen with a central cage, designed to allow the piglets to feed from their mother while preventing her from ...
By 1300 most forests had been felled, and pigs became scavengers. In a medieval British text, a woman explains that she won't serve pork because pigs "eat human shit in the streets."
Whether it's pigs, dogs, or cats, it takes a special person to care for an animal with special needs. These animals need extra attention, medical care, love, and financial consideration and sadly ...
The first person to breed for the Hereford color pattern in pigs – and the first to describe it – was R.U. Weber of LaPlata, Missouri. [4]: 611 From about 1902 until 1925 a number of farmers in Nebraska and Iowa, among them John Schulte of Norway, Iowa, collaborated in the selection of pigs with this coloration.
