Finally, there is the life cycle cost, or how much a roof will cost you over the years. A shake roof may start out at around $12,500, but after a 40 year cycle the cost of the roof can rise to almost $45,000 when you calculate in maintenance and repairs, a yearly cost of over $800.
Toucan is tropical bird, best known by its large, colorful bill. There are 40 different species of toucans that are widely distributed in Mexico, Central America, South America, and Caribbean.
A: Toucans are preyed upon by jaguars, margays, owls and boas. Despite its large bill, a toucan has little in the way of defending itself against predators. To defend itself against potential predators, a toucan must rely on sound to scare off any animal or human it feels is a threat. Toucans use their loud, shrill voices to scare away predators and may sometimes beat a tree branch with their bills to warn their enemies away. A toucan cannot use its bill to fight off a predator. It's bill is hollow and made of keratin, and therefore, not strong enough to withstand a fight.
