The length of each bird species account varies, depending on whether the bird is native or a “visitor” (the book’s term for migrant) or vagrant, breeding or non breeding. They breed in dense colonies, incubate their single egg on the feet, and take more than a year to fledge a chick.

According to the HBW, when breeding, male birds do most of the incubation and parenting while females often leave the nest up to one week before the eggs hatch. According to Couzens, after laying the eggs, females sometimes immediately abandon their first mate and pair up with another male. How efficient. How surprising.

The last example suggests the difficulty of making a clear distinction between an animal part and an animal product.
