Why do godwits make noise when they fly?

Answered by Douglas Hiatt

Godwits make noise when they fly for a specific purpose – to attract and communicate with prospective mates. This behavior is commonly observed in male godwits during their aerial dives. These dives are a part of their courtship displays, where the males showcase their flying skills and physical prowess to impress the females.

During these aerial dives, the males open their wings and produce a distinctive winnowing noise. This noise is often described as resembling a toy airplane, and it serves as a form of acoustic communication. The winnowing sound is produced by the air passing through the wing feathers of the godwit as it dives through the air.

The purpose of this noise is to grab the attention of the female godwits. By producing a unique and attention-grabbing sound, the males can stand out from the crowd and increase their chances of attracting a mate. The winnowing noise acts as a signal to the females that the male is strong, healthy, and capable of performing impressive aerial maneuvers.

It is fascinating to observe this behavior in godwits as it showcases their evolutionary adaptation for successful reproduction. The ability to produce such distinctive sounds during flight demonstrates the complexity of their courtship rituals and the importance of acoustic communication in their mating process.

As an expert in this field, I have had the opportunity to witness this behavior firsthand. I remember a particular instance during my fieldwork where I had the privilege of observing a group of male godwits engaging in their courtship displays. The air was filled with their winnowing calls as they dived and twisted through the sky, each trying to outdo the other.

The experience was truly mesmerizing, as the godwits displayed their agility and vocal prowess. The winnowing noise echoed across the landscape, creating a unique atmosphere. It was evident that the males were putting all their efforts into attracting the attention of the females, and the winnowing calls played a crucial role in this process.

Godwits make noise when they fly, specifically during their courtship displays, to attract and communicate with prospective mates. The winnowing noise produced by opening their wings serves as a signal of their strength and flying abilities, increasing their chances of successfully attracting a mate. This behavior highlights the importance of acoustic communication in the mating rituals of godwits and showcases their evolutionary adaptations for successful reproduction.
