Semi-collared kingfishers are solitary and usually live alone on branches or rocks near the water, hunting for food, mainly Nile herring, crabs, frogs, and insects, and even catching butterflies in flight. He sits and waits for a long time to catch the bass, and when he spots a fish, he dives after it. When a kingfisher plunges into the water, it can also maintain excellent vision because its eyes can quickly adjust the contrast in the Angle of view caused by the light in the water. So the fishing ability is very strong.

Semi-collared kingfishers generally nest on river banks, the size of the nest and the behavior of the adult bird is very similar to that of the common kingfisher, usually digging vertical burrows in the bank, and the nest overhangs plants to conceal the opening. The entrance is not very high, so some birds often drown in the rising water. Usually 3-4 eggs are laid, and both sexes hatch together. But only the females feed the chicks. The young may stay in the nest for about 27 days and soon be able to fly. Egg laying varies from region to region: from January to May and October in Tanzania, from July to March in Zimbabwe and from September to October in Zambia.1388ed8aa61ea8d34899236f9a0a304e241f5891_九雷图片转换器.jpg
