Seasonal and diel patterns of song output by great reed warblers Acrocephalus arundinaceus.

Popis výsledku v původním jazyce

We examined seasonal and diel singing activity budgets of great reed warblers in two areas of Central Europe in three different ways, over a period of ten consecutive years. Song was recorded from 12 April to 3 August. Males exhibited regular singing activity after arrival with a peak in the second half of May and beginning of June, Thereafter their activity continued to decrease and almost ceased in mid-July. In both study sites great reed warblers exhibited similar seasonal patterns of singing activity. There was a significant difference in the rate of singing between daylight and the dark (88.7% and 11.3% respectively); this ratio was similar over the whole song-period. We found similar singing rates in the first and the second half of the day. Thechanges in singing activity were connected with twilight**. The period of daylight alternating with the dark stimulated song output of great reed warblers. In the morning, two to three hours after twilight, activity increased considerably
