| Proper noun for birds | ||
After we have a preliminary understanding of birds, we
will encounter some observation problems. For example, some birds can
be seen in certain seasons, but not in other seasons; some birds are
different in the looks of male and female birds, even young birds grow
up into a different appearance. So how do we understand this part? At
this time, bird pictorials play a great role. These terminologies help
communication, circulation and research during observation. We simply
organize according to Taiwan wild bird hand-drawn pictorials so as to
help readers understand the introduction of bird terminology: | ||
| Bird habitat time
Birds are divided into permanent birds and migratory
birds according to the season and length of stay in the area. Permanent birds:Permanent birds are birds that appear throughout the year and have a breeding record.Migratory birds:Migratory birds are birds that migrate with the seasons. They are divided into three types: winter migratory birds, summer migratory birds, and transient birds according to the season and duration. Usually, they do not appear in the area for at least several months a year. 1.Birds that stay in the area for winter, usually arrive in autumn and leave in spring. Strayer: Birds
which are not the bird species in this area originally, and appear in
the area due to natural factors such as bad
weather and other force majeure factors.2.Birds that remain in the area for breeding usually arrive in spring and leave in autumn. 3.Migratory birds making only a short stay in the area, usually transient in spring or autumn. Introduced extraneous species: Species that originally do not belong to the area, but appear in the area through unnatural methods. Example: Egyptian holy bird which is alien bird. Naturalized species: Refers to the species used to be introduced species, which can be integrated into local life after a period of time. Naturalized species are better. Like the magpie introduced to Taiwan in the Qing Dynasty, they have been naturalized and reproduced well, and are listed as permanent birds. | ||

| Difference of species
A taxonomic species is the smallest basic taxonomy. In
simple terms, species that live in a certain geographic distribution
area and have the same appearance can be mated and reproduced under
natural conditions, and the offspring still have the ability to
reproduce, are called species, subspecies refers to the same species
that have different forms due to long-term isolation due to different
reasons, such as: beak length, body color, courtship action, which is
different form produced to adapt to different regions, such species of
changed forms are called subspecies compared with the original species. Endemic subspecies: Subspecies that are restricted to specific areas.Endemic species: Species that are restricted to specific areas, such as 27 endemic species of birds in Taiwan. There are 27 endemic species of endemic birds in Taiwan’s wild bird illustrated handbook. According to the frequency of occurrence of birds in the area, they are also divided into rare, not common. If the bird records are rare, it means that the probability of the bird being observed is less than 10%, it is not easy to see and it means that the number of birds is relatively rare. Bird growth and feather change
The appearance of birds during growth is relatively
large. Therefore, when we observe birds, we must be able to distinguish
between appearances. For example, Tiger Bittern are very different in
appearance from young birds to adult birds. Adult is clear in feather
color and has fertility. Immatures are between young birds and adult
birds, and their feathers are intact, some have the colors of adult
feather, and some juvenile bird species have fertility. Juveniles'
feathers have just grown and they have just learned to fly. After the
chicks’ feathers grow out, they can be roughly divided into two types:
early-formed, the eyes of which can be opened when the bird's shell is
broken, and the body has feathers, which can peck on itself away from
the nest; some birds half-early formed, and still need to depend on the
parent bird for feeding; late-formed, after the shell emerges, the
whole body is naked and has no feathers. The mouth is big, and the eyes
if of seams. It cannot move and needs to be fed by a female bird.
Changes in bird feathering are also one of the key
observation points. Breeding feathers refer to the feather color of
adult birds during breeding, and are often referred to as summer
feathers in summer. Non-breeding feathers are feather colors that adult
birds change during the non-breeding season. They are usually called
winter feathers in winter. Ornamental feathers are feathers that adult
birds grow for breeding purposes, thereby attracting the opposite sex
for breeding purposes. | ||
After knowing the terminology of birds, we can
easily understand the communication terms between birders, and we can
easily understand the meanings recorded in the bird illustrated
handbooks, and we have a further understanding of bird watching. |
