Chimney Swifts suffer from fewer chimneys. Scott Burnet leads Lehigh Valley Audubon Society’s effort to help.

What is the problem

Chimney Swifts spend most of their life on the wing. But even they need to nest and, during migration, roost. Historically, large hollow trees served this function. But as large trees became rarer, chimneys replaced them. Today, even chimneys are becoming rarer as they are capped or taken down. This contributes to the Chimney Swift population falling. BirdLife International states that between 1966 to 2007 the population came down by 90% in Canada and 50% the USA. Counting survey blocks in the PA breeding bird atlas with confirmed nests, the numbers are down by more than 50% between the 1980s and 2000s.

What has been done

Existing chimneys need to be saved. Chimney Swifts do remember chimneys from year to year so keeping traditional roost sites available is important. And that has happened. LVAS has helped secure assurances that the chimney at Muhlenberg College will remain. Same thing with the 200 year old chimney at Lehigh Parkway. Both nice places to witness flocks of swifts swirl in right before sunset.

To reverse the negative trends that is not enough. New chimneys are needed. Hence we have towers that only serve Chimney Swifts.

Scott Burnet and his team of volunteers have so far built four towers in the Lehigh Valley. Starting in 2012 Scott built his first tower by his garage. In 2013 and 2014 two towers came up around Lake Muhlenberg. One tower on the island and the other on Cedar Beach. You might have seen the information kiosk around the one at Cedar Beach. This year one tower is coming up at Lehigh Gap Nature Center and another in Mertztown, Longswamp Township.

All these efforts have now started to bear fruit. The first nests have been confirmed in the Cedar Beach tower.

How to build

Building a tower takes both expertise and money. It quickly becomes apparent that without experience managing construction projects and a rich network of contacts, towers remain a dream. Challenges include getting permission to build, negotiating access to equipment, identifying price worthy material, and finding volunteers. And not least, having the grit to synchronize all the pieces. We are lucky to have such a person in Scott. Hearing Scott describe his kayak trips with ladders and swinging 60lb tower sections while balancing on a 10ft ladder in the dark just reinforces that image.

Thank you

LVAS has many to thank in addition to Scott.

  • James Hardie Corporation contributed siding material

  • Dries Lumber helps with material

  • Dan Kunkle’s group Color of Nature has volunteered many hours of work

  • Friends of Allentown Parks and Karen El Chaar has helped with funding and assistance

  • Lynn Serfass has helped with funding

  • And many volunteers have contributed to this success

What is next?

More towers will come up and you can help. Look for LVAS emails, facebook posts, and Meetup events where you can volunteer. You can also donate money via our website. If you prefer, you can earmark your donation to tower construction.

LVAS Chimney Swift towers now proven to be used by the species for nesting

Scott Burnet (LVAS Habitat Committee Chairman), and his wife Linda Shankweiler (LVAS Social Committee Chair) discovered two Chimney Swift nests on 8/27/16, in the LVAS swift tower located just east of Cedar Beach pool in Cedar Creek Parkway, near Lake Muhlenberg. Today marked the first internal inspection of this tower, since it was completed in fall of 2014. Single birds had been observed entering the tower during the day, both during breeding season last spring and this spring as well. It was hoped that nesting had occurred, but today's discovery of actual nests provides physical evidence. As a follow up, Scott and Linda plan to do an inspection of the tower on the island at the lake tomorrow morning (8/28). This will be the first internal inspection of this tower since the causeway to the island was removed two years ago. Access is now only possible via boat, and with permission from the Allentown Parks Dept. It is hoped that similar findings will be made there also, as swifts have been observed entering that structure during nesting season over the past few years since that tower was finished in late summer of 2013.
