The arrival of the rainy season has awakened all life on the grassland. This year's rainfall has been abundant. After several heavy rains, not only the grass grows vigorously, but also the migrating herds return to the delta. The permanent residents of this grassland, a large number of people walking - Lewen Mobile Caterpillars like the net live on the ground, make a living by eating grass, and can crawl freely on the ground. Generally, they appear on a large scale every ten years or so. Herbivores don't like them. The caterpillars will compete with them for food, but the insect-eating birds are very happy. The amazing number of army insects means that they will not have to worry about food in a short time.
This kind of caterpillar that swaggers around on the ground and grass stems is much easier to catch than the bugs hiding in the soil. Of course, it tastes great too.
Many birds living on the grassland come to this feast.
The big long-legged stork and some smaller birds are catching marching insects in the grass. Although they also like to follow the vultures to pick up or snatch carrion, they also like to catch prey themselves. Their big mouths are very flexible to pick up the soft caterpillars, throw them lightly, and swallow them into their mouths. For storks, army insects are too small and they need to eat constantly to satisfy their appetite. However, you never need to worry about food during the rainy season. The nests of the Quelea are also an important source of food for the storks. Seed-eating queleas live in groups and like to build nests close together. In the trees where the Qualea finches live, you can always see hundreds or even thousands of bird nests woven from grass and small branches, densely packed together. The little quelea lives inside. The only thing the stork has to do is to stand on the branch, maintain its balance, then lower its head and use its long beak to take the chick out of the nest.
The whole process is like a free buffet.
