Cf. \u201cAtlantic Booby\u201d.<\/em><\/strong>\u00a0 \u201cAtlantic\u201d and \u201cForster\u2019s\u201d Boobies are extremely similar but rarely if ever overlap.\u00a0 \u201cAtlantic\u201d is known only from the Atlantic Ocean and \u201cForster\u2019s\u201d is known only from the Indian and Pacific Oceans, but both are highly mobile and could occur nearly anywhere.<\/p>

Male \u201cAtlantic\u201d and \u201cForster\u2019s\u201d have approximately the same plumage but are fairly easy to distinguish by the color of their facial skin: orange on \u201cAtlantic\u201d versus dark-blue on \u201cForster\u2019s\u201d.\u00a0 Their foot color also differs: orangish-yellow on \u201cAtlantic\u201d versus greenish-yellow on \u201cForster\u2019s\u201d.<\/p>

Even with clear, high-resolution images, female Brown Boobies are not always assignable to a particular form.\u00a0 To distinguish female \u201cAtlantic\u201d and \u201cForster\u2019s\u201d, the key features are the coloration of the bill, facial skin, and feet:<\/p>

Bill Color:<\/u>\u00a0 Female \u201cAtlantic\u201d has a consistently pinkish bill, whereas \u201cForster\u2019s\u201d tends to appear more yellowish or ivory, but sometimes has a pinkish hue.<\/p>

Facial Skin and Foot Color:<\/u>\u00a0 Female \u201cAtlantic\u201d has pure yellow facial skin and feet, whereas \u201cForster\u2019s\u201d appears closer to white or greenish-yellow.<\/p>

Immatures appear to be indistinguishable until they begin to show a distinctive aspect of their adult coloration\u2014such as the paler facial plumage of male \u201cBrewster\u2019s\u201d or \u201cAtlantic\u2019s\u201d yellower feet.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
