Fifty-four
years ago H and I had been hiking a scenic trail in northcentral
Pennsylvania and camped near a small spring on the edge of the
Allegheny Plateau. We’d settled in and were asleep in our sleeping
bags when we were jolted awake by a call that’s been described as
“Who cooks for you, who cooks for you ALL!” sounding from right
above our tent.
The
origin of the nighttime
racket that woke us was a barred owl (Strix
varia)
calling to another barred owl that answered from a distance. The
back-and-forth calls continued for quite a while until our overhead
neighbor moved on.
Barred
owls favor forests of large trees, with a
mix of hardwoods and conifers near streams, wetlands or wooded swamps, there they feed on small mammals, birds, reptiles and
amphibians – and
even earthworms –
To
produce the future generations
of barred owls, the birds nest in a variety of locations – they sometimes use the abandoned nest of a hawk or crow (which they line with
conifer twigs), but prefer a large tree cavity or nest box –
Some barred owls are surprisingly tolerant of humans, remaining perched on
a limb and not flying off at the first sign of a person. A
friend who rehabilitated injured birds from ducks to eagles always
said that owls are stupid. That may or may not be true, but they’re
certainly not as mentally capable as ravens or crows.
Barred
owls range from southern Canada to the Gulf of Mexico and have
recently extended their range to the west coast where they
out-compete and sometimes hybridize with the smaller, related and
endangered spotted owl.
Barred
owls tend to be sedentary, not traveling much once they’ve
established a territory, and do not migrate. They’re also long-lived, there’s a
record of one living more than 26 years in the wild.
The
birds hunt at night where their superb hearing enables them to detect prey moving amid fallen leaves or beneath snow.
Daytime is spent roosting on a
tree limb, often that of a conifer, or in tree cavities; they apparently mate for life and both birds
of a mated pair often roost in close proximity.
Forests of large old trees are becoming scarce, and big trees with large cavities are especially uncommon in managed forests – where will the barred owls go?
