Waterfowl Migration Update

Join us in celebrating the snow goose migration in Pennsylvania. This live stream from Willow Point at Middle Creek Wildlife Management Area in Lancaster County is brought to you by the Pennsylvania Game Commission and HDOnTap. The best times to view snow geese on the lake are sunrise (before they leave to feed in neighboring fields) and sunset (as they return from feeding to roost). Other species of waterfowl including tundra swans, Canada geese, and many species of ducks can be viewed throughout the day. Learn more about the snow geese migration at Middle Creek in this webinar. Enjoy! And remember, nature can be difficult to watch.

View periodic estimates of the numbers of various waterfowl visiting and annual summaries below the live feed.



ADVISORY: Please note that these numbers are estimates and subject to rapid and dramatic change. Major weather events including snow and freezing temperatures can quickly impact the number of birds that can be found at Middle Creek. These updates are submitted by Lauren Ferreri, Middle Creek manager.

MIGRATION BACKGROUND: The period that annually attracts the most birds, and visitors, remains late winter. During this timeframe, large numbers of migrating waterfowl normally appear. In recent years, more than 100,000 snow geese, 10,000 tundra swans, 10,000 Canada geese, and a wide variety of ducks have stopped at Middle Creek while pushing north to their breeding grounds. It's also a great place to see northern harriers, or "marsh hawks," nesting and immature bald eagles, and more common creatures such as white-tailed deer and red-tailed hawks.

There are many variables that determine the arrival of migrating waterfowl. The most significant is icing. When the ice on the main impoundment thaws to create areas of open water, the birds begin to arrive. Snow cover on the surrounding agricultural fields also influences the arrival waterfowl because it can limit access to the waste grains these birds depend on for food. Therefore, areas of open water and limited or no snow cover on adjacent fields strongly influence Middle Creek's drawing and holding power for migrants.

Many of the migrants that come to Middle Creek winter south of Pennsylvania and usually begin to push north in conjunction with spring thaw. During extreme winters with a late thaw, however, there's always a chance waterfowl will fly over Middle Creek, or stop only briefly. Timing is critical for migration and nesting.

Exactly when birds arrive can be difficult to predict. Generally, the birds, when conditions permit, begin to arrive in late February or early March. For those planning a trip to Middle Creek, the first weekend in March would be a good time to visit. A map of the area is available at the Visitors Center, as are the latest updates and bird sightings. Make sure to bring along binoculars, and field guide to help identify some of the birds you'll see. Warm clothes also an important consideration if you plan to drive with your windows open. A camera also is usually worth taking, because sometimes tremendous photo opportunities arise at Middle Creek.

After stopping by the Center, visitors follow the self-guided driving tour to Stop #1, located at the lower end of the lake. This is normally an excellent site to view tundra swans. Another suggestion would be to hike to Willow Point. At dusk or dawn, this provides the best vantage for snow geese. To fully appreciate Middle Creek, a drive through the interior on the Tour Road shouldn't be missed. Weather and driving conditions permitting, the Tour Road will open March 1. A significant portion of the interior remains Propagation Area where entry is prohibited. It is because of the Propagation Area that waterfowl are attracted to Middle Creek. Within these areas, the habitat and lack of human disturbance remain the primary reason why Middle Creek has become such a vital stop to migrating waterfowl.
