【November 30 2016】If these two cattle egrets really are having a spat, it’s likely over which one has the best insect-eating spot on the zebra’s back. The common name for these birds comes from their penchant for standing atop cattle, zebras, antelope, and even rhinoceroses, so they can gobble up the flies, ticks, and other pests the larger animal attracts. This Burchell’s zebra may not be delighted about the squabble on its back, but it’s a small price to pay for steady pest control.Explore breathtaking Gallery from the HuluTrip homepage over the past 5 years..
