Bird Topography
Bird Topography defines landmarks on different species of
birds. Ornithologists (bird researchers) have named each
unique part or characteristic of birds. With so many species
of birds to identify, the task is daunting for beginners and
seasoned birders. Becoming comfortable with bird landmarks
takes practice, but is necessary to identify specific species.

Bird Adaptations
Did you ever wonder why there are so many different shapes
of bird beaks or feet? Beaks are multi-functional tools. Birds
use them to weave nests, defend territory, attack competitors,
groom feathers, communicate, and most important, to gather or
capture food. The beak shape can tell you what a bird eats.
Feet also tell you a lot about a bird’s feeding behavior
and also where the bird spends most of its time.
If you want to learn more about birds, pay attention to
beaks and feet! Knowing these characteristics makes bird
identification easy. To help you get started, here are some
common bill shapes and the type of food each bill is specially
adapted to eat.
|
|
Beaks (bills)
|
Birds eat almost every kind of food, but not all birds eat
the same things. Your best clue as to what a bird eats is its
bill. Bills are dining utensils. They work like hammers,
chisels, pincers, nutcrackers, hooks, spears, or strainers. |
 |
 |
Probe
Hummingbirds have long, tubular bills that resemble
straws, which they use to sip nectar from flowers. |
 |
Funnel
Flycatchers and goatsuckers have wide bills surrounded by
a net of bristles that work to funnel flying insects into
their mouths while in the air. |
 |
Chisel
Woodpeckers have strong, long, chisel-like bills to make
holes in trees for nests or food. |
 |
Spear
Mergansers and herons have long bills with serrated edges
and a hooked point, adapted for grabbing fish. |
 |
Strainer
The edges of a duck's bill are fringed to strain plants,
seeds, and small animals from mud and water. |
 |
Cracker
Sparrows, finches and grosbeaks have thick, conical beaks,
for cracking open the hard outer shells of seeds to reach the
nutritious center.
|
 |
Tweezers
Blackbirds, Warblers, and Meadowlarks use their long
pointed bills to probe for insects. |
 |
Tearing
Hawks and eagles tear prey, such as mice, into bite-sized
pieces with their strong, hooked bills. |
 |
Burrowing
Many shore birds, avocets, and stilts have long, thin
probing bills. These bills come in a variety of sizes to
jab at different depths in the muck. This allows many
species to live together within their own niche without
directly competing for food |
|
Feet
|
Feet carry birds to their food and some help deliver food
to the bird. They are designed for running, perching,
grasping, wading, paddling and even more.
To hold onto a twig, a passerine bird needs feet with
opposing toes that wrap around the branch. Why don't perching
birds fall off when they sleep? When a perching bird sits, a
ligament in its feet automatically locks on the limb. With
feet locked, sleeping birds don't fall. As the bird stands up
the ligaments release.
|
 |
Semi-aquatic Birds
Rails have special lobed feet that help them walk on top
of marsh vegetation. These birds are not confined to water and
walk on dry land quite well. |
 |
Waders
Long-legged birds can wade in shallow water to reach prey
buried in muddy marshes. The long toes of herons and egrets
support walking on mucky stream and lake bottoms. |
 |
Paddlers
Birds with webbed feet can paddle through the water and walk
on mud. The web spreads out when pushing the foot backward
providing more surface to thrust the water. When the foot is
drawn forward the web folds up so there is less resistance to
the water.
|
 |
Walkers
In open
grasslands, most species walk or hop on the ground to find
food. |
 |
Climbing
Parrots and woodpeckers use their zygodactyl feet to climb
up walls and trees. Parrots use their nimble toes to hold food
and bring it to the beak. |
 |
Grasping
Hawks and owls capture, kill, and carry prey with their
feet. Their recurved talons are distinctive. Owl feet are
special because they can rotate one toe toward the back making
them zygodactyl at will.
|
 |
Scratchers
Partridges, pheasants, and quail use their strong feet to
scratch the dirt and leaf litter to uncover seeds and insects.
