If you live in the contiguous United States, you’ve almost certainly seen (or heard!) an American crow. Crows range from southern Canada throughout the United States. As an adult, this bird is entirely black from bill to tail, except for its brown eyes. Adult crow feathers have a glossy sheen. These noisy birds are often recognizable by their distinctive, loud cry, called a caw. They are often mistaken for the common raven, but ravens are larger, have differently shaped bills, pointed wings and tails, and hoarser cries. American crows often live in family groups. Both members of a breeding pair help build the nests, and the female crow usually lays four or five eggs in the spring or summer. After about five weeks in the nest, the young birds begin learning how to fly and catch prey. Crows sometimes stay near the place where they were born to help raise other young crows. Crows gather in large groups during the winter. They congregate late in the day in areas with large trees. This behavior is known as winter roosting. Crows will eat almost anything, from insects and small animals such as frogs to fruit and nuts. They prefer open areas with access to trees and can sometimes be found around vegetable gardens. Crows also frequently live in suburban neighborhoods and in parks. Crows are considered to be very intelligent birds. Text by Sara Zeglin / NGS Staff

When a great white shark is born, along with up to a dozen siblings, it immediately swims away from its mother. Born on the east and west coasts of North America, the south of Africa and southwest Australia, baby sharks are on their own right from the start. Their mother may see them only as prey. At birth the baby shark is already about 5 feet (1.5 meters) long; as it grows it may reach a length up to four times that. The pup (which is what a baby shark is called) will live its life at the top of the ocean’s food chain. But before it grows larger, the pup must avoid predators bigger than it is—including other great white sharks. Many baby sharks do not survive their first year. Young great white sharks eat fish (including other sharks) and rays. As they grow, the sharks’ favorite prey becomes sea mammals, especially sea lions and seals. Sharks count on the element of surprise as they hunt. When they see a seal at the surface of the water, sharks will often position themselves underneath the seal. Using their tails as propellers, they swim upward at a fast sprint, burst out of the water in a leap called a breach, and fall back into the water with the seal in their mouths. They can smell a single drop of blood from up to a third of a mile (0.53 kilometers) away. Sharks don’t chew their food; they rip off chunks of meat and swallow them whole. They can last a month or two without another big meal.
