alauda arvensis การใช้

• As early as 1773, it was established that birds learned calls, and cross-fostering experiments succeeded in making linnet " Acanthis cannabina " learn the song of a skylark, " Alauda arvensis ".
• During the breeding season of the skylark ( " Alauda arvensis " ), particular common sequences of syllables ( phrases ) are produced by all males established in the same location ( neighbours ), whereas males of different locations ( strangers ) share only few syllables.
• In the Skylark ( " Alauda arvensis " ), playbacks of neighbour and stranger songs at three periods of the breeding season show that neighbours are dear enemies in the middle of the season, when territories are stable, but not at the beginning of the breeding season, during settlement and pair formation, nor at the end, when bird density increases due to the presence of young birds becoming independent.
