These plants begin life as epiphytes, when their seeds, often bird-dispersed, germinate in crevices atop other trees. These seedlings grow their roots downward and envelop the host tree while also growing upward to reach into the sunlight zone above the canopy. An original support tree can sometimes die, so that the Strangler Fig becomes a "columnar tree" with a hollow central core. (Wikipedia)
Its common name is popularly thought to derive from the crest of long quill-like feathers, lending the bird the appearance of a secretary with quill pens tucked behind his or her ear, as was once common practice. A more recent hypothesis is that "secretary" is borrowed from a French corruption of the Arabic saqr-et-tair or "hunter-bird". (Wikipedia)
The long legs, which increases the bird’s height to around 1.3 m tall, help him catching his favourite prey: snakes.
