Habitat

The Magnificent frigatebirds are normally found in marine, tropical saltwater and terrestrial habitats. They love building their nests using twigs.

Magnificent frigatebirds live in colonies. One colony is likely to occupy around 500 meter-stretches along the shoreline. Barbuda is a small island in the Caribbean where as many as 2500 of these birds found in pairs can be seen. This is the home of the largest colony of magnificent frigatebirds.

Description

The males are rather different from females in terms of appearance. Males are entirely black only that their inner secondaries are brown especially on each side of the upper wing. Then of course, there is the gular pouch which is red in color and which is inflatable. If you are very keen, you will notice a purple gloss mainly on the forehead. On the region of the neck, you will notice a green gloss. The same case applies to the upper wing. They have legs that are black in color. In a few species, they have a grayish hue.

Female Magnificent frigatebirds are entirely black except for white markings their wings and chest. Their feet and legs are either pink or flesh-colored. The females lack the gular sac. The females are almost 15 per cent larger compared to their male counterparts. Young female magnificent frigatebirds have a white head. The chest also has shades of white but the rest of the body is completely black. Their bills have a light bluish hue. The same case applies to the feet and legs. This makes these birds look magnificent in the real sense of the word.

The heads of females are so distinct that you can easily identify them from a distance. They have forked tails, which are also easy to identify. When these females are soaring at high altitudes along coastlines, their silhouettes are very easy to make out. The hooked bill is the most distinguishing feature for this bird.
