55.2 Local Movement and Long-Range Migration

55.2 Local Movement and Long-Range Migration

• The lines show the different frequencies the birds produce.
• The juvenile white-crowned sparrow will sing an abnormal song if it is kept in isolation or only hears the song of a different species.
• If the juvenile is exposed to the white-crowned sparrow song, he will sing it.
• YoungCuckoos are reared by parent birds of different species because they lay their eggs in other birds' nest.
• Unlike the whitecrowned sparrow, adult cuckoos sing their own song, not that of the host species.

• Learning occurs during a brief critical period and establishes a long- lasting behavioral response to a specific object or individual, such as recognition and bonding to a parent.
• Konrad Lorenz studied Imprinting in the 1930s.
• Young birds of some species imprint on their mother during a critical period that is usually within a few hours after hatching.
• It would be hard for the mother to keep track of her offspring as they walk or swim, so this behavior serves them well.
• The offspring keep a record of the mother.

• Young ducks or geese need to learn to follow their mother's movements quickly in order to survive.
• After raising greylag geese from eggs, Lorenz used himself as a model for imprinting.
• After hatching life, geese prefer the company of Lorenz and other humans to geese.

• They follow their mother but can be made to imprint on humans.

• Konrad Lorenz, an ethologist, was shown in studies to be an object that young geese saw after hatching.

• Animals imprint in different ways.
• Distinguish between kinesis and taxis, two different types of local trick used in sheep farming is to disguise a lamb.

• Experiments determine if abandoned lamb smells like her own.
• Animals use visual or olfactory clues to learn.

• The roaches tend to be hundreds or even thousands of kilometers apart.
• Several dif are moving away from the light.
• The photosynthetic ferent types of behavior may be involved in these movements.

• In this section, we explore local movement and move toward a light source.
• Sea turtles use landmarks to guide their movements.
• We will be attracted to the light.
• When they emerge from their nest, they look at the possible mechanisms used by the bright spot to find their way.

• The simplest forms of movement are responses to stimuli.

• Some freshwater fishes move away from the source of the stimuli.
• The woodlice move through their gills and help them from being washed downstream.

• Sometimes memory and landmarks can be used to aid in local move, which can keep them in damper areas.
• The female avoid desiccation.

• The wasp flew genetically programmed events.
• Each time a honeybee leaves the nest, she catches and stings it.
• He thought that they paralyze it, return to the nest, drag the bee into the nest, and learn the position of the nest by creating a mental map of the land.
• The egg feeds on marks in the area.

• Tinbergen adjusted his hypothesis before it was fully developed.
• The wasp needs to catch and sting the landmarks around the burrow to get the bees.

• The digger wasp uses visual landmarks to locate their nest.

• The female digger wasp digs an underground nest and brings food to her offspring inside.

• Repeated experiments show that the wasp uses landmarks.

• Two pieces of cardboard are coated with pine oil.

• After the wasp leaves the nest, move the pinecones 30 cm from the nest, but leave scented cardboard at the nest.
• The pinecone nest is 30 cm from the Move pinecones wasp nest.

• The seventeen wasps were studied in two steps.
• The five wasp were studied in steps 3 and 4.

• The positions of visual landmarks are used by digger wasp to aid in local movements.

• When the wasp was out hunting, he moved the circle to get the learning.
• He thought that the wasp could be a distance away from the real nest and constructed a sham one, responding to the scent of pinecones rather than their making a small depression in the sand.
• He put a circle of pinecones in the entrance of the burrow.
• The wasp flew straight to the that had no scent and two small pieces of cardboard coated in pine sham nest and tried to locate the entrance.
• Tinbergen chased it.

• It flew back to the sham nest.
• Tinbergen left scented cardboard around the real nest.
• The wasp chose the sham nest nine times.
• Tinber was once again ignored the real nest, and flew Gen got the same result with 16 other was, and not once did they to the sham.
• He concluded that the wasp was choosing the real nest.

• Some of them had alcohol in their system.

• In 100 hours of observing, an accurate bee shape was not a neces event.

• The topic is about animals.
• The question concerns how digger was able to locate suitable prey.

• For example, almost half of the bird species of North America use visual migration to escape the cold winters to find their prey in South America.
• You will return to North America in the spring to breed.
• You know that digger was use visual landmarks to locate to feed in the winter and then return to breed because of the understanding you gained from Figure 55.7.
• Their nest was staggering.

• The northward journey of bee scent is an interesting point.
• If the results of the experiment indicate that digger was complete, place a check mark in each of the columns.
• They may be responding to bee shape, bee movement, or bee butterflies laying eggs and dying.
• The milkweed scent leads to the development of the caterpillar.
• If they are not, place a minus.

• Spain butterflies migrate to a small area in Mexico to avoid the cold weather in the north.
• They roost in large numbers in fir trees.
• There are butterflies in Florida and Cuba.
• Young starlings didn't fly in coastal California.
• The monarchs take a route to Spain.

• The return journey has a cycle that happens several times.

• There are no overwintering sites in France or England for the northward and southward migrations.
• The individuals have never been to the destinations in the southwest.
• When juvenile were captured in the Netherlands, they must have had an innate ability to migrate.

• Adult birds may be involved in piloting, orientation, and navigation when captured and moved.

• Many whale species migrate between summer feeding areas and Earth's magnetic field.
• Birds have magnetite in their beaks.
• Refer back to Section 44.4 Sea near Alaska to coastal areas of Mexico for information on gray whales.
• navigation can be aided by the stars line, mountain ranges, and rivers.
• Pigeons follow a compass bearing but also adjust it.

• When the pigeons are released, they breed in Scandinavia and northeastern Europe, and migrate in display of predictable deviations in their flight.
• The orientation of the birds is shifted every hour when the southwest direction is shifted to the internal clock.

• Some examples of animal migration are not understood.
• The green Netherlands was transported south to Switzerland.

• It is not known why the turtles lay their eggs on this speck.
• This result shows how they find the island.
• The juvenile birds rely on Ascension more than the adult birds on other beaches.

• Scientists have made many discoveries about animal navigation, including the position of the Sun, the stars, and how animals acquire a map sense.
