Black Noddy

Anous minutus melanogenys
Black noddy

Black noddies’ forehead and crown are grayish white, extending back on the head. Their forked tail is slightly grey and the remaining plumage is brown with black legs and feet. They appear blacker than the brown noddy and have a longer, thinner bill and whiter cap with straighter demarcation at lores than the brown noddy.

Courtship consists of head nodding and fish transfers. Extensive nests are built in trees with grasses, leaves, and twigs. Old nests are sometimes renovated and reused. On Midway, noddies have adapted to nesting in tall ironwood trees (Casuarina equisetfolia). Nesting occurs throughout the year on Midway, with peak activity in January, February and July and August. In the absence of ironwood trees, noddies nest in naupaka (Scaevola sericea) and beach heliotrope (Tournefortia argentea) shrubs in the Northwestern Hawaiian Islands. One speckled egg is laid. Incubation lasts approximately 36 days. Incubation shifts average about one half day.

Chicks are brooded for several days after hatching with feedings approximately once every 11 hours. After about three weeks adults spend little time with chicks, except for feeding. Chicks are fed regurgitated fish or whole fish as they get older. Fledging occurs approximately 36 days after hatching. Post-fledging feeding continues for several weeks.
