The Imporatance of Various Environments Surrounding a Tidal Flat to Conserve the Endangered Waterfowls in the East Asian-Australasian Flyway

SDGs

Waterfowls in Asia are decreasing due to the degradation of habitat. Although protecting main coastal wetlands is significant, the importance of surrounding environments like paddy fields and reservoirs for waterfowls are scarcely known. Therefore, this research investigated how two kinds of spoonbills use different environments near Imazu tidal flat. The result was that spoonbills use the tidal flat and other sites such as reservoirs, artificial creeks and so on for different purposes. This result implies that the conservation of central coastal wetland is not enough for waterfowls, but we should reconsider the importance of surrounding environments for waterfowls.

Very good ecological observation! Can you discussed the feature of the behavior by a place?

Comment

Thank you for your comment. There is a pattern of spoonbills' behaviors. -The sites of "tidal flat", "artificial creek between paddy fields", and "river" were used for foraging. -The sites of "colony" (trees near the tidal flat for egrets) and "reservoir" was mainly used for resting(sleeping) -"paddy field" was also used for resting, but the rate of sleeping is lower than the other sites, but the rate of loafing is higher, which implies they may temporarily rest after the foraging in creeks. They clearly use several sites for different purposes and it may be because a tidal flat fluctuates due to the sea movements, so they cannot depend on only tidal flats.
