Asian Koel in courtship feeding

 - 

In Asian Koel courtship, the male presents the female with food, specifically ripe fruit, as part of their courtship display. This behavior, known as courtship feeding, is a common practice in many bird species and may play a role in strengthening the pair bond and providing extra nutrition to the female during egg formation.

Courtship feeding is when a male bird gives food to a female bird as part of their courtship ritual.

 It's most common when courtship is over, and can be a valuable source of nutrients for the female. 

When does courtship feeding occur? 

During egg formation, during laying, and during incubation. 

What's the purpose of courtship feeding?

To provide nutrients for the female. 

The Yellow-vented Bulbul (Pycnonotus goiavier analis) is the most common bird in my backyard. Its bubbly call is a wake-up sound in our parks and gardens

The yellow-vented bulbul eats berries and small fruits. It also sips nectar, nibbles on young shoots, and consumes some insects.

Hornbill Courtship feeding - dating

A male bird offers food to his mate

Courtship feeding is a misnomer. It describes behavior when a male bird offers food to his mate, but it occurs most frequently when actual courtship is over. Most courtship feeding occurs during egg formation, laying, and incubation and can provide a valuable source of nutrients for females. 

(From the British Trust for Ornithology)

The Malaysian pied hornbill is common in my backyard. A pair of males and females fly low and make a loud call. This adaptable species feeds on figs, palm fruits, guava, papaya, rambutan, and wild fruits from nearby plantation.

Malaysian pied hornbill. (Anthracoceros albirostris)

When a male bird offers food to his mate, it's called courtship feeding. It's a common behavior during egg formation, laying, and incubation. Why it happens Courtship: In spring, male birds may offer food to attract a female and establish a pair bond. Nutrition: The food can provide a valuable source of nutrients for the female, especially when she's incubating eggs and can't forage for herself. Promise: The male may be promising to help feed the nestlings. (From Generative AI)
