Third Search for Eagles, 11 March 2012
The third 2012 Dr. S. Marie Kuhnen Memorial Field Trip, Search for Eagles took place in the Delaware Valley Sunday, March 11, 2012 from 8:00 a.m. to 4:30 p.m. with nine participants. The temperature at the start was 32 degrees and at the finish doubled to 64 degrees. It was a clear gorgeous day. The day began with watching feeder birds at the Pocono Environmental Education Center (PEEC) that included Dark-eyed Junco, Black-capped Chickadee, Tufted Titmouse, and Fox Sparrow among others. We logged 147 miles in the Delaware Water Gap National Recreation Area and Upper Delaware Scenic River from PEEC. The trip concluded at the headwaters of the Lackawaxen River.
Jack Padalino, president emeritus of PEEC and the Brandwein Institute, a partner with the National Park Service, led the search that included seeing 39 species of birds with 12 Bald Eagles (BE), 7 adults and 5 immature birds.
The first raptor of the day was a Red-tailed Hawk perched west of Route 209 at the Heller Farm. At the Bushkill Access in the Delaware Water Gap National Recreation Area were Song and Lincoln’s Sparrows, 2 Common Mergansers, 25 Canada Geese and 2 Mallards. The first BE, an adult was seen on the New Jersey side of the river flying over a corn field. About 5 minutes later the adult was joined by an immature BE. A Sharp-shinned Hawk was spotted perched above the entrance to the access.
A Red-bellied Woodpecker was at the Eshbacks Boat Launch. No eagles at the Dingmans Ferry Access; however, Common Mergansers and a flock of Dark-eyed Juncos greeted us. Blackbirds including Red-wings, Rusty, and Common Grackles were flying around the Dingmans Bridge.
I have been unable to monitor the BE nest near mile marker 17 on Route 209 because the highway is closed to traffic due to storm damage and construction on the Raymondskilll Creek bridge. This nest has been active for at least the past five years.
The nine of us rendezvoused at the Callahan House, headquarters of the Brandwein Institute. Our third BE of the day was an adult seen flying down stream along the Sawkill Creek and over the historic Callahan House where our group was watching feeder birds. We added White-throated Sparrow.
At Milford Beach another adult BE soared above us soon after we watched a Red-shouldered Hawk lift itself high above us on a thermal current. A heterospecific flock of over 800 Blackbirds, Red-wings, Rustys, and Common Grackles flew above us from the PA to NJ side of the river. Well in the distance north of us were two skeins of Canada Geese of about 500.
An adult BE was in the Milford nest that has recently been reconstructed. Last year the nest crashed to the ground and the BEs began immediately constructing a new nest on the north side of the creek.
Our next BE was seen flying over the nest, above the ridge at the westbound lane of I 84 opposite the Kittatinny Camp Ground. As we were watching a perched Red-tailed Hawk two Common Ravens performed above us. Next we watched the perched RT fly above the ridge with talons extended. It was joined by another RT. Both birds remained in the air together for a few minutes then left it to soar overhead. We were hoping for the RTs to do their courtship display, locking talons and tumbling through the air. In addition to the two Red-tailed Hawks, and a Turkey Vulture were Ravens soaring above the ridge.
On our way to the Riverview Restaurant we were treated to 7 RTs along the way.
At the Riverview Restaurant near where PA, NJ, and NY converge 50 Ring-billed Gulls were present as were Common Mergansers and Mallards but no eagles. Along the shore where we were standing was a group of Canada Geese with 3 Killdeer.
We enjoyed a rest stop at the Pennsylvania Welcome Center where we viewed an Eagle Institute exhibit and a diorama of the Roebling Bridge
No eagles were seen from the Eddy Pond Resort overlook; however, we were greeted by Common Mergansers, 50 Canada Geese, Mallards, and 300 Ring-billed Gulls.
By Noon we were at the Hawks Nest historical marker. Great vista with 2 Ravens, An immature BE, 3 RT, and 4 TVs.
At the Pond Eddy nest sight in a White Pine on the PA side of the river we saw an adult BE in the nest. Driving north to Pond Eddy we had a RT high above the ridge and an adult BE dropped behind the trees on the PA side of the river.
As we crossed the bridge approaching the Mongaup Reservoir Observation Blind we searched upstream for BEs to no avail, there were none.
There were no eagles to be seen along Plank Road or from the Rio Reservoir Dam. This was the first time this eagle search season that no BEs were seen on the Mongaup – Rio loop. We returned to the Delaware and traveled upriver. As we passed Pond Eddy again we had a RT high above us as well as an immature BE. The BE was still in the nest.
No eagles were at Minisink Ford observation blind; however, a RT put on a display above us.
The Eagle Institute is where a video of area eagles is screened and where brochures, newsletters, and information about eagles is made available to visitors. There is a gift shop and the Institute is open weekends; however, the Institute was closed for the season.
Approaching the confluence of the Lackawaxen and Dellaware Rivers opposite the Zane Grey Museum an immature BE was flying along side. An adult BE was spotted in the distance upriver. High above us was a skein of 50 Snow Geese, difficult to spot, but still a treat as was the 20 Tree Swallows.
At the confluence of the Lackawaxen and Delaware rivers above us on the north side of the river is an active BE nest. We were able to locate the nest with a BE in it.
No BEs were seen as we traveled upstream along the Lackawaxen and concluded our field trip at 4:30 p.m. but were able to see one more RT as we returned to Milford.
Eagle observation data that we collect is shared with members of the Sussex County Bird Club, Eagle Institute, and Hawk Migration Association of North America HMANA.
An Eagle identification field guide and a “Search for Eagles” hand-out was provided for participants by the Paul F-Brandwein Institute. Join us in the future to Search For Eagles. Four searches will be planned next season: December 2012, January 2013, February 2013, and March 2013.
