Common wasps are social insects and live in nests of up to around 10,000 workers. They build a paper nest in a hole in the ground. The paper is made by the wasps who chew small amounts of wood from trees, reeds or garden fences and mix it with saliva to form a pulp which is added to the nest in thin strips.
Bower birds The most notable characteristic of bowerbirds is the extraordinarily complex behaviour of males, which is to build a bower to attract mates. Depending on the species, the bower ranges from a circle of cleared earth with a small pile of twigs in the center to a complex and highly decorated structure of sticks and leaves — usually shaped like a walkway, a small hut or a maypole — into and around which the male places a variety of objects he has collected. These objects — usually strikingly blue in hue — may include hundreds of shells, leaves, flowers, feathers, stones, berries, and even discarded plastic items or pieces of glass. The bird spends hours carefully sorting and arranging his collection, with each object in a specific place; if an object is moved while the bowerbird is away he will put it back in its place.
