February Recitation work After readting the parsaraph bewow, answer the qss thot folow were koterested in studying ditferences in the frequency of foraging beheviors atchers (birds) in Calfornia They were distribution of foraging behaviors was associated with interested in determining the overall the stage of the breeding cyele of the two species Here are some of the data The number of foraging behaviors observed by stage of the breeding cycle for Hammond's and Stage of Breeding Cyele - rdSpeciesforag ngllehaviorire incubation ncubation, oding port,Brooding cher Flycatch yeatcher Source: Noon, B. R., and Sakail, H. F. (1990). Variation in the foraging behaviors of two flycatchers: associations with stage of the breeding cycle. Studies in Avian Biology, 13: 237-44 1) What is true about the conclusion that all foraging behaviors continually increased from the pre-incubation breeding stage to the post-brooding? This occurred for both species of flycatchers. his occurred for Hammond's flycatchers but not for Western flycatchers. C) This occurred for only the hover-glean foraging behavior in Western flycatchers. D) This occurred for only the glean foraging behavior of Hammond's flycatchers 2) Suppose that Hammond's flycatchers tend to forage as individuals while Western flycatchers ctend to forage in groups. Which prediction is most reasonably related to foraging costs? Hammond's flycatchers would be more likely to show decreased foraging efficiency. 8) Hammond's flycatchers would be more likely to show increased foraging efficiency Vestern flycatchers would be more likely to show decreased foraging efficiency D) Western and Hammond's flycatchers would show equivalent foraging efficiency 3) Which foraging behavior-species combination showed the greatest range of number of foraging behaviors? A) Hammond's-glearn B) Hammond's-hover-glean 0) Western-hover-glean D) Western-flycatch Copyright 2018 Pearson Education, Inc.Explanation / Answer
Foraging is search for food, it is important for a animal to survive and reproduce. It studies the animal behaviour and mode used for praying in the environment it lives.
Fly catch method – catching the fly that approach them
Hover glean – by flying catching a prey
Glean – catching prey form leaf, ground
The answer is a) this occurred for both species of fly catcher.
The answer is a) Hammond’s flycatcher would be more likely to show decreased forage efficiency.
From the table the western flycatcher hover glean showed the increased foraging behaviour.
c) Western - hover glean
4) Scientist choose 15m pole and dropped the shell from various height on the rock. He recorded the number of drops required to break the shell.
Yes hypothesis supports the researcher’s observation.
c) If the crow dropped the shell in the height of 15m it requires 4 times to be dropped and total flight height is 60, So crow needs to spend high amount of energy to fly 4 times in order to break the shell.
d) This type of foraging is not innate it is learned.
