Adapted for the Night Owls
differ from other birds in having soft, frayed edges to their flight feathers
which allows them to fly in silence and capture prey undetected. All have acute
hearing and enormous eyes, which provide excellent vision in low light. Most
owls are also extremely well-camouflaged so that they can remain undetected
when roosting quietly during the day.
All owls lay their eggs in cavities, on the ground
or in a nest built by another bird, as it is obviously impossible for a
nocturnal bird to gather nesting material of any kind. All owls lay pure white
eggs and these are seldom left unattended - the incubating adult always sits
tight, sometimes even to the point of allowing itself to be picked up by a
human researcher. Some owls can be very aggressive, however, and a European
Tawny Owl was responsible for the removal of renowned bird photographer Eric
Hoskings eye several years ago! Spotted Eagle Owls can likewise be very
defensive over their young and will not hesitate to dive-bomb and strike an
unwary bird-watcher.
In this short feature, we take a look at just four
of the species that make the African night so wondrous . . .
The Cosmopolitan Barn Owl The Barn Owl
is one of the most widespread birds in the world, with populations on all
continents and on many remote oceanic islands. It is able to breed prolificly
in years when its rodent prey is abundant (often following above average
rainfall) with a record clutch of 19 eggs having been recorded; these owls
frequently occupy the nest of the Hamerkop, much to the annoyance and agitation
of the hard-working builders! (two such nests are under observation by CCAfrica
guides at Ngala Game Lodge in South Africa and Matetsi Water Lodge in
Zimbabwe). The eerie screech of this ghostly-white owl is certainly a sound to
send a shiver down the spine of the uninitiated, but it is a harmless - and in
fact very useful bird, as far as people are concerned, for it helps to
control the numbers of rats and mice.
