The 'End of the Day' winning image was taken by Majed AlZa'abi from Kuwait who, along with the top prize, earns the title of 'Bird Photographer of the Year 2020.' Majed's image was also the winner of the Best Portrait category. The top title of 'Bird Photographer of the Year 2020' carries a £5,000 cash prize. Waterfalls are amazing places for photography, with a variety of wildlife sometimes framed by rainbows caused by the mist of the cascades. In Iguazú's unique environment, the 'swifts of the falls' find the perfect shelter for breeding.

"This Northern Hawk-owl spent several hours in the top of the tree, looking over the winter landscape for food," the photographer explains. "As I realized the bird was very bold and fearless, I carefully launched my drone and approached it very slowly. The owl did not react, and allowed the drone to hover reasonably close."

The photographer of the photo above explains that this is a frequent sight in Kaziranga National Park during late winter, when every year forest officials set the grassland alight, patch by patch. The practice is an element of habitat management. The grasslands support a large number of herbivores, ranging from Indian Hog Deer to the Vulnerable Indian (or Greater One-horned) Rhinoceros. Tall grasses start to dry off by January, which reduces their nutritional value. Burning the grasses allowsd new, nutritious grasses to grow. The practice also arrests the successional process whereby grassland eventually becomes forest, a process that is known to have increased thanks to vegetation mapping surveys of India. Kaziranga is divided into approximately 30 blocks based on various features, such as vegetation and natural topography. Each block is burned one by one and patch by patch. "During the burning, a plethora of birds congregate near the site to eat insects that are driven out by the fire," the photographer notes. "We had stopped near one such burning site when we spotted a huge congregation of Indian Rollers. Here, a roller can be seen sitting on a pole waiting for the right moment to grab a bite."
