Bird watching is like an addiction. Once you are hooked, there is no
getting away from it. Since doing so is hopeless, you need to
understand the terminology you will here.
Abmigration is the movement of a bird from one breeding area to another
by pairing in a flock with a bird from the new area. They then travel
during the next season.
Air sacs are a section of a bird's respiratory system. They are
attached to lungs and extend throughout the body cavity. Depending on
the species, can temporarily store large amounts of air to cool the
body and maximize oxygen intake.
A Field mark refers to distinctive characteristics used by a birder to
identify particular birds in the wild. Field marks can be coloring,
shapes, size and so on.
Paddling is a term that carries a different meaning than you might
think. It does not refer to peddling through the water. Instead, it
refers to stamping the ground to motivate food such as worms to pop up
where they can be eaten.
The term Papilla refers to a colorful knob often found on the beak or
mouth of a hatchling. It acts as a target for the parent to place food
upon return to the nest.
Photoperiodism refers to the reaction of birds as well as other animals
and plants to the changing amounts of sunlight in a day during the
year. Breeding periods and migration are believed to be triggered by it.
The rump of bird is an area often critical for identification purposes.
It is the area just above the tail feathers. It is often distinctly
colored and/or shaped, which helps with classification.
The act of stooping refers to a predator bird hunting smaller birds. It
is the equivalent of the car chase in a movie. The predator will chase
the smaller bird until it captures or fails.
When it comes to birds, their display is all about communication. The
display involves positioning their body in such a way to convey
meanings regarding territoriality, mating and such.
As you know, the legs of birds are odd. The tarsas is the element of
the leg that is just below the leg and above the ankle. It is
considered part of the ankle anatomy.
Nalospi is a measurement that helps in the classification of sighted
birds. The Nalospi is the distance between the tip of the bill and the
forward edge of the nostril. It is not always easy to see and calculate.
The nape of a bird is another potential classification mechanism. It
refers to the area between the crown of the head and neck. It often is
an area of demarcation, making it helpful in identifying the bird you
are seeing.
The act of gleaning refers to birds that pick their food off of upright
structures such as trees. Some do it while hovering, but many may just
land on the structure and whip their head back and forth to find food.
The important thing to understand about birding is the language is
important, but not critical. Gaining an appreciation of our feathered
friends through observation is the key.
