Weaver bird essay in English for 5th standard
Answers
Answer:
Weaver bird nests are extraordinary structures.
Most individual nests are cylindrical in shape, with downward-facing, narrow entrances that are usually situated over or next to water.
Ensuring that the entrance faces downwards and is as narrow as possible deters thieves and potential predators. Some nests even have a long tube, extending the entrance further beneath the nest body.
Having selected a good location for his nest, the weaver bird starts to loop and weave strands of grass or strips of leaves around the ends of one or two branches in a tree. Having created a looped basis for the nest body, the weaver bird then builds the hollow body before adding the tubular entrance last.
The males are the main weavers, leaving the females with the responsibility of selecting their breeding-partner. They do this based on the location, design and relative comfort of the nest which ensures the good genetic quality for the father of her offspring alongside a safe home for her eggs.

The nests provide a more consistent environment for sociable weavers who inhabit an area whose climate can see a fluctuation of extremes. Protected from the intense heat of the day and sometimes brisk night-time temperatures, sociable weavers can raise their young and ride out extreme weather in relative comfort, all the time safe in the knowledge that they are surrounded by members of their own species. However, despite this "safety in numbers" it has been found that nest raiding can be quite high with up to 80% of young not making it to adulthood.
