| 1 | Diel and seasonal patterns of variation in the singing behaviour of Savannah Sparrows (Passerculus sandwichensis)显示文摘Background:The vocalizations of birds are dynamic traits that often vary in output with time of day and time of year.By quantifying patterns of diel and seasonal variation in vocal output,we can gain insight into the ecology and evolution of birds and the function of their vocalizations.In this investigation,we quantified diel and seasonal variation in song output by studying a breeding population of Savannah Sparrows (Passerculus sandwichensis).Methods:We used autonomous recorders to collect extensive recordings across the breeding season in a long-term, colour-marked study population of Savannah Sparrows in eastern Canada.We described diel and seasonal variation across five different breeding stages based on recordings of more than 50,000 songs from 34 males.Results:During the pre-breeding stage, prior to female arrival, males sang a pronounced dawn chorus with a peak in song output during the early morning.During the breeding stage,in contrast,the dawn chorus was diminished and males instead exhibited a pronounced dusk chorus with a peak in song output during the evening.Across the breeding season,the highest levels of song output occurred in late April and early May,soon after males arrived on the breeding grounds,and the lowest levels occurred in August,prior to the departure of birds for the wintering grounds.Conclusions:These patterns suggest that Savannah Sparrows' early-season dawn choruses are directed at males and serve a territorial defense function.Later-season dusk choruses,in contrast, appear to play a role in attracting mates and possibly acoustic mate guarding. | Ines G.Moran Katrina C.Lukianchuk Stephanie.M.Doucet Amy E.M.Newman Heather Williams D.Ryan Norris Daniel J.Mennill | 2019 | Avian Research2019，10，3： | 3 |
