judging by the hundred or so tree-top nesting females.
Egrets dance, sing, and nest, on trees with formidable thorns, to keep less talented predators away.
I found this recording on you tube of the egret’s most peculiar courtship song. It is much louder in person with many birds courting, dancing and singing, at the same time. ( Thank you Kim DeGiulio Goecke, who I do not know, who accurately recorded their songs):
Cheers to you from the dancing and singing tree-top birds~
