Have
you ever heard a trilling or clicking noise at night? Or maybe a high pitched
whinnying or a screech? You might have just heard the call of an Eastern Screech Owl.
They are capable of making a large variety of sounds, the three most common of which
are a monotonic trill (the pitch doesn't change), a high whinny that descends
in pitch, and a loud clicking that they make with their beaks. These sounds can
be heard most commonly during the night, but they can be heard during the day
as well if a group of small birds start to mob the owl. You might not see the
owl at first though.
Eastern
Screech Owls have a very good camouflage. Red and gray are the two different morphs of color they come in, although grey is far more prominent among the owls. A
brown-ish color is also becoming more common for the birds and can make it
difficult to tell the difference between the red and grey morphs of color.
Their plumage (feathers) is made specifically to help them blend in with their
surroundings and you might just skip over them if you don’t look close enough.
Camouflage is a major advantage for the small owl, because while it is a hunter
and doesn't need its prey to see it, Screech-Owls are also between six and ten
inches long, which makes them prey for larger birds. Here at the Nature Center,
we have two Screech Owls; one red morph, and one grey. This way, you are able to compare
the two and see their size. The wingspan of these beautiful birds is anywhere
from nineteen to twenty-four inches, but they only weigh between four and eight
ounces, which leads to very small hatchlings.
Baby
Screech Owls hatch with their eyes closed, which leaves them very vulnerable
for the first part of their life. They usually come in clutches between two and
six, and are as white as the eggs they hatched from. Screech Owl eggs are
almost perfectly circular and are usually just over an inch in diameter. These
eggs hatch after about thirty days and the babies are fully dependent on their
parents for food for up to ten weeks after they begin learning how to fly. At
this point they are called fledglings and the most common way for them to learn
to fly is for the young owl to jump out of the nest and onto the ground before
trying to hop and flutter its way back to the top. It’s not uncommon for hikers
to find baby owls in the woods and think that they are abandoned, which is not usually the case. If you find a baby owl in the woods, chances are that
it’s learning how to fly, and its parents will be most happy if you just leave
the fledgling alone so that it can climb back up to its nest and tell its
siblings about the adventure it just had. Learning to fly is a slow and tedious
lesson for the young owls, but it is what gives them the ability to hunt. This
gives them independence and once the skill is fairly mastered, they begin
traveling farther and farther away from the nest, until they are living on
their own and ready to start a family. Screech Owls are usually monogamous,
which means that they only have mate in their lives. There have, however, been
cases in which a male would have two different mates at different times, but
that is rare. Chances are, if you see an owl family in the woods, the parents
will be together for the rest of their lives.
Eastern
Screech Owls are native to all of Ohio and can be found almost everywhere east
of the Rocky Mountains. They prefer areas with tree coverage, and tree cavities
or nesting boxes are absolutely essential because they do not build their own
nests. These small owls live and breed very well in or near farmland and suburban
areas, which Ohio has plenty of, because of the abundance of small rodents,
invertebrates (which include earthworms, crayfish, frogs, and insects), and
small birds. They have even been known to prey upon bats, which is highly
impressive given that bats are extremely agile flyers. These small birds of
prey are one of the most successful owls in Ohio and are the most common owls in
our state. Its ability to adapt to human influence and broad diet are but a few
of the reasons. So, next time you take an evening hike, listen carefully, and
you might just be surprised by what you hear.

personal contact with local naturalists and personal experiences) is this

Feel free to click on the link and navigate the page
to verify my facts and expand on things that I didn't include, or to hear each
of the calls of the Screech Owls that are described in the first paragraph
along with several others. If you want to see one of these beautiful birds up close and in person, come stop by Gorman Nature Center. We will also answer any questions you have to the best of our knowledge both on here and in person.
Do you have any pictures of Screech Owls? If you have
any (either taken in the wild or here at Gorman Nature Center), I would love to
see them. Feel free to email me the picture (gncintern@gmail.com) and I will post it on this blog (with your permission and name to give you the credit).
Also, are there any animals native to Ohio that you
are interested in or want to know more about? Leave a comment to help me decide
what my next topic will be.
Thank you for reading!!
