Question

Ответьте на вопрос и обоснуйте свою точку зрения. Способность птиц к навигации доказана многими опытами. Птицы, сидящие в клетках, в состоянии предмиграционного беспокойства всегда ориентируются в сторону зимовок, если они могут наблюдать за положением солнца или звезд. Например, когда чечевиц перевезли с побережья Балтийского моря в Хабаровск, они изменили свою ориентацию в клетках с юго-восточной на юго-западную. Зимуют эти птицы в Индии. Гипотеза ориентации птиц в перелетах по астрономическим источникам света в настоящее время подкреплена материалами опытов и наблюдений. Какая по типу у птиц навигационная способность? Обоснуйте свои ответ.

Answer 1

Ответ:

Бионавигация.

Объяснение:Способность животных в выбору направления при сезонных миграциях по современной теории обусловлена остротой органов чувств и инстинктами вида. Механизмы разнообразны (кроме птиц миграции совершают например млекопитающие (киты, северные олени и тд)), но изучены не достаточно, чтобы гарантировать, что именно что-то одно: астронавигация, наземные ориентиры имеют решающее значение.

Answer 3

Navigational Abilities of Birds

Birds have demonstrated remarkable navigational abilities, allowing them to undertake long-distance migrations and find their way back to specific locations. These abilities have been studied extensively through experiments and observations. One hypothesis regarding the navigational abilities of birds is their reliance on astronomical light sources for orientation during migration.

Navigational Abilities of Birds and Astronomical Light Sources

Research suggests that birds use various cues, including the position of the sun and stars, to navigate during migration. For example, birds in pre-migratory restlessness, also known as zugunruhe, show a consistent orientation towards their wintering grounds when they can observe the position of the sun or stars. This behavior has been observed in birds kept in cages, where they align themselves in the direction of their migratory route based on the available astronomical cues [[1]].

Orientation Shifts in Captive Birds

Experiments involving captive birds have provided further evidence of their navigational abilities. For instance, when migratory birds such as dunlins were transported from the Baltic Sea coast to the city of Khabarovsk, their orientation in cages shifted from southeast to southwest. This change in orientation suggests that the birds were able to adjust their navigational behavior based on the new astronomical cues available to them [[2]].

Supporting Evidence from Experiments and Observations

Numerous experiments and observations have supported the hypothesis that birds rely on astronomical light sources for navigation during migration. For example, studies have shown that birds can use the position of the sun as a compass to maintain a specific direction during their journey [[3]]. Additionally, research has demonstrated that birds can use the stars as a reference point for orientation, even on overcast nights when the stars are not directly visible [[4]].

Conclusion

Based on the available evidence from experiments and observations, it can be concluded that birds possess navigational abilities that allow them to orient themselves during migration using astronomical light sources such as the sun and stars. These abilities enable birds to undertake long-distance journeys and find their way to specific wintering grounds. However, it is important to note that while the hypothesis of navigational abilities based on astronomical cues is supported by research, there may be other factors involved in bird navigation that require further investigation.
