Long-Tailed Widowbird
These South African birds are named for their almost all black
coloring and, of course, their extremely long tail. The tail of the
males can be over 16 inches long, which is more than twice their body
length.

Royal Flycatcher
There are 4 species of royal flycatchers all with the “royal
crown” which is generally only on display during courtship rituals and
competitions with other males. Usually the crest is lying flat but opens
up like a fan.
