Vocal exercises also help male birds better impress females with their songs during the day.
As noise pollution increases, light pollution usually does too. So, increased light from growing cities can also cause birds to start chirping earlier. Researchers used to believe that birds sang in the morning because the cooler temperatures carried their voices farther. After running tests, they discovered that their voices went just as far in the morning as the afternoon. However, increased noise pollution does explain why morning might be the best time to sing.
Early morning singing also acts as a sort of competition between males. A male bird wants to sing as loud and clear as possible to show female birds that he’s a stronger, more healthy bird than his rivals. Morning chirping is usually the loudest and most frequent in the spring. This is when most bird species start breeding.
However, when each bird starts singing depends on the species. Some birds start an hour or 2 before sunrise, while others wait until the morning is closer. Birds usually stop chirping once the sun rises over the horizon. The bright light signals to them that it’s time to start their day. The dawn chorus is so popular among birders that there is an international day to celebrate it! On the first Sunday in May, bird enthusiasts wake up extra early to listen to and witness the beautiful birdsong.
If you want to attract more birds into your yard, it’s super easy! Just research the types of birds native to your area and provide them with a suitable birdhouse and seed. Adding a birdbath to your yard is another simple way to invite more songbirds into your yard.
