The Green Kingfisher (Chloroceryle americana) is the smallest of the three different Kingfisher species found in the United States. The male Green Kingfisher has a broad, rusty coloured band covering its breast which often features some green spotting on the flanks. The female tends to feature buff-white colouring on her underparts which is broken by two green chest bands – the two bands help to differentiate her from other kingfisher species. The green of the Green Kingfisher may vary from an oily dark-green to a rich hunter-green.
