Concept explainers
To review: The differences between imprinting that occur in geese with the song development in sparrow.
Concept introduction: The behavior of the offspring is largely influenced by the environment in which it completes its development.
Explanation of Solution
The “song development” in sparrows is a “gradual process” that takes place in stages. The nestling bird listen the song of parent sparrow for fifty days and memorizes it. After maturation, they sing a preliminary note called subsong. They compare this song with the one that they memorized and when the two songs match, they finalize it. They then sing this song for the rest of their life.
The behavior of offspring is determined by the factors such as physical and social environment. Some behaviors such as to recognize the mothers in geese is very crucial for the survival of the offspring. Hence, development of some behavior is very beneficial for survival.

- In an investigation of fruit fly behavior, an enclosed choice chamber was used to test whether the spatial distribution of flies is affected by the presence of a substance placed at one end of the chamber. To test the flies’ preference for different substances, 50 flies were introduced into the choice chamber. A piece of ripe banana was placed at the end of the chamber on side A and a piece of unripe banana was placed at the end of the chamber on side B (Figure 1). The positions of the flies were observed and recorded at the start of the experiment and after 10 minutes (Table 1).arrow_forwardWhat are some behavioral adaptations that help the fennec fox survive in the desert?arrow_forwardIdentify the type of behavior. 1) 2) Goose.

Example: sparrow babies learn how to sing exactly at the same frequency as the mother. But if the babies grow isolated from their mother, the singing frequency will be different. 4) A turtle draws its head back into its shell when its shell is touched. After being touched repeatedly, the turtle realizes it is not in danger and no longer hides. This is an example of 5) : A child might stop throwing tantrums after his/her favorite toy is taken away after each tantrums.arrow_forward
- Female mimicry by males occurs in many species. For example, in the Broadley’s flat lizard (Platysaurus broadleyi), some males have the brown coloration of females while others are far more colorful (Whiting et al. 2009). Female mimics do secure some matings in the territories of their larger, more colorful rivals. Why are the bigger males (and those of the marine isopod Paracerceis sculpta) ever fooled into tolerating a female mimic? Why do female mimics occur in any species if the mating success of these individuals is lower than that of the bigger territorial males?

Sex-specific infanticide occurs more often at nests that can be flooded during the rainy season. Sons spend longer in the nest than daughters. Link this factor to why it might be adaptive for a parent parrot to kill a son in a vulnerable nest occupied by offspring of both sexes.
