For example, overnight on April 24, the answer was 963,500 birds. Migrating birds can fly as high as 10,000 feet — or as low as 100 feet. This app was created by the Cornell Lab of Ornithology.

To celebrate this spring migration, our Lycoming County Audubon chapter is getting into full swing with its annual spring bird walks. These walks are open to the public and are appropriate for new or experienced birders, and kids are always welcome.

This local audubon chapter is known for its friendliness to new birders, so give them a try. They also have loaner binoculars for both adults and kids and field guides to speed up learning about birds.

If fortunate, on the bird walks, you might see magnificently colorful birds such as the scarlet tanager or red-winged blackbird.

Below is more detail about some of the spring Audubon bird walks:

• May 2: A walk in a wooded area of Grampian Hills, right in town. You might expect to see woodpeckers or newly returning warblers.

• May 16: A walk on Skyline Drive, which is an old paved road now closed to vehicles. The sloped walk gently ascends Bald Eagle Mountain.

• May 22: A kid-friendly walk at RPANA in South Williamsport to explore birds and wildflowers. This walk is sponsored by the James V. Brown Library, and registration is required by visiting their website. The event is free and begins at 10 a.m.

• May 30: A walk in Farrandsville, Clinton County, for more advanced birders. In this unique landscape, one can expect to see more unusual birds, especially less common warblers such as the Louisiana Waterthrush, Northern Parula, Cerulean and Worm-eating warblers as well as Scarlet Tanagers and Hermit Thrush. Note: This walk may be cancelled so check the website for updates before making the trip.

• June 6: The Therapy Brewing business (outside Pennsdale) also turns out to be a birdy place. Join audubon for a bird walk led by the property owners. After the walk, the group will return to the brewery for refreshments.

• June 13: For a truly unique birding experience, this event visits an Amish farm near Jersey Shore where large numbers of purple martins nest annually. For many years, this Amish family has had steady success convincing purple martins to return to the family’s condominium bird houses. This event begins at 6:30 p.m. and is not to be missed

Detailed driving directions and descriptions of each bird walk can be found easily by visiting the Audubon website: LycomingAudubon.org. Most of these walks begin at 8 a.m. and no registration is required.
