The Java sparrow (also known as the weaver bird) is a small songbird that is typically a flocking bird in its natural habitat. The following are some behaviors that Java sparrows may exhibit before laying eggs:
Changes in reproductive behavior :
Breeding behavior between males and females can change. Males may begin to sing more frequently, dance, or perform other eye-catching acts to attract females; while females may begin to search for suitable locations to lay their eggs.
Nest building behavior :
Female birds may exhibit nest-finding behavior, which includes searching for and selecting suitable materials for nest building.
Materials for finding a nest :
Female birds will exhibit behavior of searching for nest decorations, such as leaves, twigs, and other soft materials.
Mining behavior :
If it is a terrestrial munia, the female may exhibit nest-digging behavior, searching for a suitable location to lay her eggs.
Changes in appetite :
Some female birds may experience an increase or decrease in appetite before laying eggs. This behavioral change may be related to their body preparing for egg laying.
Warning behavior :
To protect their nests and prepare for egg-laying, Java sparrows may become more alert and react more strongly to disturbances.
These pre-egg-laying behaviors can vary depending on the environment, individual characteristics, and season. They reflect the unique behavioral patterns of Java sparrows during the breeding season, indicating that they are preparing for the arrival of their offspring. If you are raising Java sparrows or are interested in their breeding behavior, close observation of these behaviors can help you better understand the reproductive behavioral characteristics of Java sparrows.
