Courtship Feeding and Mating Rituals in Terns

In many different groups of birds the male feeds the female during courtship or incubation. In nearly all birds it is the male which feeds the female. Courtship feeding is a common behavior that cements the pair-bond between mated birds also nutritional importance to the female at the time when she is forming eggs. The male offers a tidbit of food to the female, sometimes at the nest site if it has already been chosen. Courtship feeding is most pronounced, and often most exciting to watch behavior.

In most cases of courtship feeding, the female adopts an attitude and calls almost identical with those of a young bird begging food from its parents, and the male puts food into the female’s mouth. In some birds, the male simply collects the food in his beak and then presents it to the female; in others, notably in some bird groups, the male regurgitates the food to the female, as he also does when feeding the young. While this is the normal procedure there are a few variations. Thus in gulls, the male regurgitates the food on to the ground in front of the female, and the female then swallows it.

Saunders's Tern (Sternula saundersi)

In Terns, presentation of food is often preceded by a ceremonial flight or Pose. In many species in which courtship feeding occurs, the male also feeds the female on or near the nest during incubation. Hence, at this stage of the breeding cycle, the food may have real significance.

Courtship feeding is frequently seen in terns. For instance, in an effort to lure females to their territories in the nesting area, a male Saunders’s Tern carries a fish around the breeding colony and displays it to prospective mates. After a pair bond is formed, during the “honeymoon period” the male tern actually feeds the female, and soon thereafter they begin to copulate. During the following five to ten days, both sexes feed themselves, but the male also frequently feeds the increasingly dependent female. For the few days prior to egg laying the female is fed almost exclusively by the male, but this activity declines rapidly as the second and third eggs are laid.

Caspian Terns(Hydroprogne caspia) exhibit a great amount of parental care. Both adults incubate the eggs and feed and care for chicks. during early stages of egg-laying, males continue to feed females, while they lay and incubate eggs, as a courtsip acitivity. When attempting to obtain mate, unpaired males and females display the following sequence of behavior: Male captures fish and flies toward group of terns on ground, giving Fish Call and performing Fish-Bending display often several times in succession. Unpaired females on ground respond by taking flight and following male as he performs Fish Flight, also known as Low Flight: circling and flying low (10–20 m) over colony. Observations of marked terns indicate that other males and paired females whose mates are not present also join chase. After passing over standing birds up to a dozen or more times, fish carrier often lands near them, joined by pursuers. Alternatively, male lands next to lone individual (usually female) standing on edge of group. Carrying fish crosswise in bill, he approaches her and makes bowing movement with head. Female responds by ignoring male, attempting to steal fish, or initiating precopulatory behavior. Often, female actively solicits fish by begging in Hunched-Posture: Stoops low and horizontally, plumage sleeked, with neck retracted, Head-tossing from horizontal upwards. Early in season, males are hesitant to relinquish fish, and few initial interactions end with male feeding fish to female. Males may arrive with fish and perform Fish Flight many times during the day with different females. If repeated with same bird, male gradually decreases time spent performing display until he lands next to female and feeds her fish with no hesitation. Copulation often follows courtship-feeding. Males performing Low Flight and females pursuing males often visit several different colony sites per day until they acquire a mate.
