Want to learn how to identify trees? On Sunday, November 20th come out for a hike with the DOC as we learn the secrets to tree identification. We will hike in and out for a total of 2 miles at an average pace over easy terrain off RT 325 on state game lands. Meet at the Holy Spirit Duncannon Center at 9:00 am. to carpool or alternately at 9:30 am. at the intersection of RT 225 and RT 325 (parking area – 40.38867,-76.94168). Call Paul at 648-8226 or email firstname.lastname@example.org to register. For precaution purposes wear something orange.
This summer the Duncannon Outdoor Club planned a boating trip. Eight brave boaters tackled a very rough Susquehanna River from Marysville to West Fairview. High winds and water nearly swamped us as we headed from Blue Mountain Outfitters to the river left. The ledges and rocks were not visible due to the high water and whitecaps caused by the ever roaring wind. This resulted in one of the canoes capsizing, but other than a sudden dunking everything turned out okay. Once in between the islands the winds were dissipated and we were able to relax a little. All in all everyone had a great time, asking, “Can we do this again?”
When sheltered by the islands, we floated by Wade Island being careful to keep our voices down due to the nesting colonies of the endangered Great White Egrets, Black-Capped-Night Herons and the ever increasing, invading Double-crested Cormorants. Wade Island is a designated Pennsylvania Audubon Important Bird Area and is not open to the public, but can be observed by boat.
Many people are not aware that the Great White Egret is endangered, because they are a common sight in our area. However, there are only two nesting sites in PA. A small colony in York County on the Kiwanis Lake and the largest colony which inhabits Wade Island.
The Black-Crowned-Night Heron is also endangered and more illusive then the Great White Egret. Unfortunately the colonies of both these species have declined and continue to do so due to loss of habitat, water pollution, and nesting site disturbances. Such is the case of the Cormorant colony which has disturbed the nesting site, taking prime nesting spots, and damaging habitat on Wade Island by sheer numbers and nesting habits.
Cormorants used to be rare in this area, but have increased greatly in numbers over the years. It is believed that their increasing numbers are a result of expanding fish hatcheries in the south and a larger number of small fish in the Great Lakes. Cormorants nest high in trees or on the ground of islands. On Wade Island they take prime nesting habitat in trees limiting the sites for the Great White Egret and Black-Crowned-Night Heron. Feces fall in large amounts on those below and kills trees and herbaceous growth on the island. Cormorants also damage the trees when they collect nesting material. This was evident in our trip as we passed the island. This is unfortunate for the Great White Heron and Black-Crowned-Night Heron since they nest only in the trees. When all the trees die, the Cormorants are known to nest on the ground.
In 2006, 2011, 2012 and 2013 a number of Cormorants were culled by marksmen under the direction of the Pennsylvania Game Commission and the U.S Department of Agriculture’s Wildlife Services. The chart below shows the results. Note the decrease in Great White Egrets (red) and Black-Crowned-Night Herons (blue) as the population of Double-Crested Cormorants (green) increased. Gaining Information regarding future culling was attempted from various sources without success.
Some people feel that we should not cull the Cormorants and let Mother Nature take her course. Others disagree believing that mankind made the changes responsible for the increasing number of these birds, and it is mankind who must remediate the results of their actions. What do you think?

On March 12th the Duncannon Outdoor Club went to the Middle Creek Wildlife Management Area to witness the migrating Tundra Swans and Snow Geese. Middle Creek Is an important way station providing food and rest for waterfowl flying to northern breeding sites. The warmer weather triggered an earlier migration, so we were lucky to see thousands of Snow Geese. The Tundra Swans were visible only through binoculars, since they had settled down far across the lake.
After taking pictures and observing the birds and the many people observing them, we headed to the Visitor’s Center to begin our hike along a series of trails. We started at the Conservation Trail to Spicebush Trail, up Valley View Trail, down Horseshoe Trail, to Middle Creek Trail, up Elders Run Trail, back to Conservation Trail to the Visitor’s Center for a total of six plus miles. The two climbs required some effort, but lunch after the first climb re-energized us for further challenges.
We could not believe that horses could traverse down the section of Horseshoe Trail which was nothing more than a narrow, steep, deep ditch down the mountain. Horseshoe tracks confirmed that it was possible. On the Conservation Trail we were lucky to see a vernal pool, a temporary pool of surface water, full of Wood Frog and Jefferson Salamander eggs, an early sign of spring.
As with every DOC event we had an outdoor educational theme. The theme for our event was Snow Geese and Tundra Swans so we had a brief presentation before starting our hike. First we reviewed the four major flyways in North America: the Atlantic Flyway (commonly known as the Kittatinny Ridge in the Harrisburg area), the Mississippi Flyway, the Central Flyway, and the Pacific Flyway.
(Please note that the Kittatinny Ridge is being threatened by development. Refer to Kittatinny Ridge for further information on this topic and to find what you can do to save the ridge.)
The Tundra Swans use mostly the Pacific and Atlantic Flyways to reach Northern Canada and the Northern and Western edges of Alaska breeding areas. They leave their wintering areas at their lowest weight relying heavily on way stations like Middle Creek and the lower Susquehanna. When winter approaches, the Tundra Swans east of Point Hope Alaska winter on the Atlantic Coast flying 4,000 miles. Swans south of Point Hope follow the Pacific flyway to their wintering areas along the Pacific Coast.
Tundra Swans have black beaks, faces, and legs. There are small yellow spots in front of their eyes. Holding their necks in a straight position differentiates them from the Mute Swans, a feral or domestic non-native species, which hold their necks in an “S” position.
The Mute Swans are easy to tell apart from Tundra Swans, because they have an orange bill with a black knob at the base. This non-native species is very aggressive, taking and defending a half square mile as its territory. It is a very aggressive bird and will hiss, stare, hit with the wrists of its wings and attack humans. This behavior and a voracious appetite disturbs local ecosystems displacing native species like the Tundra Swan.
Tundra Swans are dabblers used to eating animal matter and nipping off submerged aquatic plants as deep as three feet below the surface. However, due to vanishing wetlands they have begun to feed on agricultural fields. Nipping off the tops of plants and eating seeds left behind after the harvest.
Tundra Swans build their nests out of grasses, sedge, mosses, and lichens on the ground in a place providing good visibility. Their territory covers a half square mile, but does not seem to impact the local ecosystem as negatively as the Mute Swans. Tundra Swan babies, called cygnets, are born with their eyes open and are in the water 12 hours after they pip the shell. They are light gray in color, are brooded by the parents for about a week, and are ready to fly after two or three months.
