Goliath Heron Ardea goliath

http://www.kenyabirds.org.uk/goliath.htm

An unmistakable Heron - with an overall length of between 4 to 5 feet this really is a huge bird! In flight it has a slow and rather ponderous look and, unlike some other herons, its legs are not held horizontallly (see the picture above). The only similar species is the purple heron, which is much smaller. Breeds at lakes Baringo and Naivasha and also the Mara River. One of the best place to see it is probably Lake Baringo where they can regularly be seen fishing around the Lake Shores...
