Question: What bird lays its egg in another bird's nest?

Answer: Cuckoo, Cowbird, Whyda, Honeyguide and Black-headed Duck

Useless Fact: These birds, called brood parasites, lay their eggs in another bird's nest and let the other bird parents feed and raise their chicks. The "egg abandoner" is then free to mate again and lay more eggs in another nest. The cuckoo is the best known brood parasite and an expert in the art of cruel deception. Its strategy involves stealth, surprise and speed. The mother removes one egg laid by the host mother, lays her own and flies off with the host egg in her bill. The whole process takes barely ten seconds. Cuckoos parasitize the nests of a large variety of bird species and carefully mimic the colour and pattern of their own eggs to match that of their hosts. Each female cuckoo specializes on one particular host species. How the cuckoo manages to lay eggs to imitate each host's eggs so accurately is one of nature's main mysteries.

Question: What is the largest invertebrate?

Answer: Colossal Squid

Useless Fact: A species of squid reported to be significantly larger than the giant squid, is called the Colossal squid, officially named Mesonychoteuthis hamiltoni. In February 2007 a live colossal squid was brought to the surface in Antarctic waters by a New Zealand fishing boat. This enormous squid, which was determined to be a male of the species, was 10 meters (32.8 feet), and weighed 450 kilograms (992 pounds), making it the largest squid (the largest invertebrate) ever captured. What is even more astonishing is that, from what scientists know about squid species in general, there is great sexual dimorphism in squids, with females being significantly larger than the males. If that holds true for the Colossal squid, this male specimen that was captured could very well be dwarfed by a much larger female of the species.

Question: What does the first letter of a radio station's call sign mean?

Question: Where was the first McD0nald's located?

Question: What is the largest insect?

Answer: Acteon Beetle or Longhorn Beetle

Useless Fact: There are different ways of measuring the size of an insect, most people would consider the largest insect to be the bulkiest and in that case the largest insect is the Acteaeom Beetle from South America. The male beetles can be 9cms long by 5cms wide by 4cms thick. If you want to measure largest by overall size, check out the South American Longhorn Beetle (Titanus giganteus) these giants can be over 16cms in body length (not including antennae) One other beetle, Dynastes hercules is also well known for reaching 16cms in length though it is not nearly as heavy. The longest insect in the world is the Stick-Insect (Pharnacia serritypes), the females of which can be over 36cm long.
