Completely. Really, birds are the messengers and communicators of nature and we've actually abused that in the past for our own means. For example, messenger pigeons.
In the morning, their sounds and calls are what helps call for dawn and for the animals to begin waking, for others (nocturnal) to begin sleeping. They do similar in late evening.
Then, if there is ever danger, say like a bush fire in the distance, them flying above squawking etc signals "danger" to other animals.
Birds are amazing animals and have some awesome personality. When I spend time in nature sometimes there will be birds that gather to where I am and start singing, sometimes they'll fly near me etc. They are really fun animals and interesting to observe. Every single bird has an individual call, like a fingerprint, and their different calls tell about different events. Hell, some bird species base their mating call off of their whole life story up until that point, then the female bird interprets that story and chooses a mate based on how good their story is.
