Large fish-eating birds called ospreys will be the center of attention on Aug. 7.

That’s the day the Division of Wildlife Resource’s Watchable
Wildlife program will host a free field trip to see the birds.

The field trip will be held in Summit County.

With their five-foot wing span, the ospreys will be easy to see. And
if you attend the field trip, you might even see some turkey vultures
and great blue herons, says Bob Walters, Watchable Wildlife coordinator
for the DWR.

To participate in the field trip, meet at the Rockport Reservoir dam
from 6 to 7 p.m.

To reach Rockport, travel on Interstate 80 to Wanship. Then exit the
freeway and travel south on state Route 32 to the dam observation site.

From the dam, participants will follow Walters in their own vehicles to
viewing sites in and near Coalville, Wanship and Rockport State Park.

If you’d like to join the field trip at one of the viewing sites,
please call Walters at (801) 209-5326 to make arrangements.

What you’ll see

Walters will have some binoculars and spotting scopes available, but if
you have your own, he encourages you to bring them.

You’ll see osprey pairs and their young during the trip. Walters
says each pair had one to three young, or eyases, this spring.

While there’s a chance you’ll see the ospreys fly, it’s more
likely you’ll watch them as they feed and exercise their wings while
on their nests. Sometimes three feet or taller in height, the nests
themselves are something to see.

“The nests start looking like chimneys,” Waters says. “Sometimes
I think they’d rather build nests than fish. It’s just
incredible.”

During the trip, Walters will also point out waters you can visit at a
later time to witness the spectacular feet-first ‘plunge dive’ of
the osprey. Ospreys make these out-of-the-air dives to snatch fish that
are swimming under the surface of the water.

Walters says ospreys are highly specialized to capture fish. Their
outer toe is reversible, and their talons are covered with sharp hooks
on the lower surface that allow them to grasp slippery fish in the
water.

Walters calls the osprey’s plunge dive ”one of the true spectacles
of nature.”
