On my post about the Prairie Falcon with prey in Box Elder County<\/span><\/a>, Utah I mentioned that I had seen some American Kestrels.<\/p>\n

I was only able to photograph one of the many kestrels I saw and I thought that he was beautiful if not somewhat unique.<\/p>\n

The male American Kestrel caught my eye immediately because he has such a pale chest that the spots on his chest stood out like tiny black jewels set in a field of snow white.<\/p>\n

The only other time I have seen an American Kestrel with a chest this pale was in Florida.<\/p>\n

Birds of North America online<\/span><\/a> (BNA) says this about Male American Kestrels:<\/p>\n

Underparts pale buff to pinkish or orange; amount of streaking and spotting highly variable.<\/em><\/p>\n

And further down their page on the appearance of American Kestrels:<\/p>\n

Considerable disagreement on how much of the variability in kestrel plumage is age-related. Bent (Bent 1938b) suggested that males become less barred dorsally, less spotted ventrally, with a more rufous tail through successive molts; Parkes (Parkes 1955a) presented contrary evidence. It is not known with certainty whether tips of rectrices in males become successively lighter.<\/em><\/p>\n

I saw the same American Kestrel yesterday and I could easily tell that it was him because of his pale chest. Unfortunately I wasn’t able to photograph him because he took off immediately.<\/p>\n

Most of the male American Kestrels I see here in northern Utah show more buff to orange coloration on their underparts than the male I photographed in Box Elder County. The male above was photographed at Farmington Bay WMA on a very gray, foggy morning and he shows more color in his underparts. I wanted to include this photo of a different male for comparison.<\/p>\n

I love to notice the small things like variations in plumage when I am out photographing birds. It keeps me on my toes.<\/p>\n

Life is<\/em> good.<\/p>\n
