Jizz refers to the general characteristics of the bird. It is used to describe its general shape, size and behavior. The specific field marks upon the crown, wing and the body are not a part of the jizz. This is useful in determining the general species of the bird. Experienced birders can determine if they have observed a particular bird in the past by consulting their records and field journal.

Birding is not just about birds. It is also about the community feeling that is very common amongst those who love this hobby. The earliest attempt to form a community was done on the radio. When it did not work, people started meeting in cafes for birding meetings. Nowadays, people have formed online clubs and forums. Hence, it is not surprising that enthusiasts have developed their own language. The word 'plastic' refers to a bird that has escaped captivity while 'dip' refers to a failed trip where one did not see the bird one wished to see.

The unique words used are not always slang words. In some cases, the word may merely be a shorter and easier to remember version of a scientific word referring to a specific region of the Earth or a specific species of birds. Corvid refers to birds that form a member of the Corvidae family of birds. Learning this language does not require a lot of effort. Simply spending time amongst those who like birding is enough to grasp the basics of this language.
