Birds are giving themselves a pep talkįor some birds, their song has been shown to affect their behavior and hormone levels. It’s strong enough to sing before it’s had the opportunity to fuel up on food. ![]() One theory is that it is a sign of vitality and eligibility if a male bird can make its presence known in the earliest time of the day. The morning is a time when birds’ energy is generally low because they haven’t eaten all night. Vociferous singing takes strength and impressive command of its breathing and beak dexterity.

This deters competitors for the food sources it has found there. If the song is heard over a wider area, the bird is effectively broadening its territory. The further the song travels, the more other birds are likely to hear it – including great numbers of potential mates. Birds want to communicate to as many other birds as possible Some studies show, however, that the sound can be carried just as far later in the day as in the early morning. In this case, singing as early as possible, when acoustics are best, would be the most effective way for a bird to deliver its message. This is ideal for the bird because its purpose in singing is to communicate the location of its territory and to attract a mate. The air is usually still and colder than later in the day when the sun has risen.įor a long time it was thought that this cooler air is more dense and will carry sound further. In the period before dawn, it is not only quiet but the air conditions mean that sound will travel further. Which makes most sense to you when you think about the birds you see and hear?

When birds perceive it to be daytime, they begin their activities. Like human eyes, though, diurnal birds’ eyes do not function in the day so they sleep at night and need the daylight to move around. This makes it seem like they wake up extra early. The actual time of sunrise and the amount of light will vary from season to season.īirds’ eyes are able to see ultraviolet light and so they detect the sun’s rays before humans are able to. ![]() There are a few theories about the reasons why birds wake up so early.īirds’ body clocks prompt them to get up about an hour before sunrise, when it is starting to get light.
