Diet

In nutrition, diet is the sum of food consumed by a person or other organism. Dietary habits are the habitual decisions an individual or culture makes when choosing what foods to eat. The word diet often implies the use of specific intake of nutrition for health or weight-management reasons. Although humans are omnivores, each culture and each person holds some food preferences or some food taboos.

This may be due to personal tastes or ethical reasons. Individual dietary choices may be more or less healthy. Proper nutrition requires ingestion and absorption of fiber, vitamins, minerals, and food energy in the form of carbohydrates, proteins, vegetable oils, and fats. Dietary habits and choices play a significant role in the quality of life, health and longevity. It can define cultures and play a role in religion.

Worm

The term worm (pronounced /ˈwɜrm/) refers to an obsolete taxon (vermes) used by Carolus Linnaeus and Jean-Baptiste Lamarck for all non-arthropod invertebrate animals, and stems from the Old English word wyrm. Currently it is used to describe many different distantly-related animals that typically have a long cylindrical tube-like body and no legs.

Most animals called "worms" are invertebrates, but the term is also used for the amphibian caecilians and the slow worm Anguis, a legless burrowing lizard. Invertebrate animals commonly called "worms" include annelids (earthworms), nematodes (roundworms), platyhelminthes (flatworms), marine polychaete worms (bristle worms), marine nemertean worms ("bootlace worms"), marine Chaetognatha (arrow worms) and insect larvae such as caterpillars, grubs, and maggots. Historical English-speaking cultures have used the (now deprecated) terms worm, Wurm, or wyrm to describe carnivorous reptiles ("serpents"), and the related mythical beasts dragons. The term worm can also be used as an insult or pejorative term used towards people to describe a cowardly or weak individual or individual seen as pitiable.

Worms vary in size from microscopic to over 1 metre (3.3 ft) in length for marine polychaete worms (bristle worms), 6.7 metres (22 ft) for the African giant earthworm, Microchaetus, and 55 metres (180 ft) for the marine nemertean worm (bootlace worm), Lineus longissimus.

Various types of worm occupy a small variety of parasitic niches, living inside the bodies of other animals. Free-living worm species may live on land, in marine or freshwater environments, or burrow.

Nelson's Sparrow

The Nelson's Sparrow (Ammodramus nelsoni) is a small sparrow. Adults have brownish upperparts with grey on the crown and nape, a cream-coloured breast with light or indistinct streaking and a white throat and belly; they have an orange face with grey cheeks and a short pointed tail.

Their breeding habitat is marshes on the Atlantic coast of Canada and Maine, central Canada, (the Canadian Prairies region and a coastal strip on the south of Hudson Bay), and the north central United States. The nest is an open cup attached to vegetation and close to the ground. Males compete for females but do not defend territories; they sometimes help feed the young. Mating is largely promiscuous by both sexes; multiple paternity in a nest is common.

These birds migrate to the southeastern coasts of the United States. They forage on the ground or in marsh vegetation, sometimes probing in mud and eat mainly insects, aquatic invertebrates and seeds. Their call is a raspy trill, almost a mechanical sound. It may be given in flight during the nesting season. The sound has been likened to a drop of water hitting a hot fry pan.

This bird was named after Edward William Nelson, an American naturalist. Formerly, this bird and the Saltmarsh Sparrow were considered to be a single species, the Sharp-tailed Sparrow; because of this it was briefly known as Nelson's Sharp-tailed Sparrow.
