Hagstrum knew that homing pigeons could hear sounds as low as 0.05 hertz, low enough to pick up infrasounds that were down around 0.1 or 0.2 hertz. So he decided to map out what these low-frequency sound waves would have looked like on an average day, and on the days when the pigeons could home correctly from Jersey Hill.
He found that due to atmospheric conditions and local terrain, Jersey Hill normally sits in a sound shadow in relation to the Cornell loft. Little to none of the infrasounds from the area around the loft reached Jersey Hill except on one day when changing wind patterns and temperature inversions permitted.
That happened to match a day when the Cornell pigeons had no problem returning home.
"I could see how the topography was affecting the sound and how the weather was affecting the sound [transmission]," Hagstrum said. "It started to explain all these mysteries."
The terrain between the loft and Jersey Hill, combined with normal atmospheric conditions, bounced infrasounds up and over these areas.
Some infrasound would still reach Castor Hill, but due to nearby hills and valleys, the sound waves approached from the west and southwest, even though the Cornell loft is situated south-southwest of Castor Hill.
Records show that younger, inexperienced pigeons released at Castor Hill would sometimes fly west while older birds headed southwest, presumably following infrasounds from their loft.
Hagstrum's model found that infrasound normally arrived at the Weedsport site from the south. But one day of abnormal weather conditions, combined with a local river valley, resulted in infrasound that arrived at Weedsport from the Cornell loft from the southeast.
The 3 birds arrived this morning in Aurora, Colorado safe and sound. Thanks. We'll do business again!!

Hello there, My name is Mike and live in Az, I had racing pigeons when I was young and now Im not young haha 61, Semi retired and determined to move to a place where I can fly birds again, want to get my grandkids involved. Anyway as a kid I flew some Sions and really enjoyed your website. When Im ready would love to get a few Sions again and see how they do. Any advice for an old newbie? lol
Hey Donnie, Saw your Birds on Ipigeon and must say, those are some Beautiful Heitzmans. They are very true to what I called the real thing. Beautiful Hansennes as well. Take Care, Chuck
Hi
I have placed the pigeon recieved from you recently in a priority express shipment back to you in same box recieved. Bird was beautiful and healthy but we realized it’s nature is such that it needs to fly and be a racing pigeon. We can’t offer that life to it and realize it was a mistake to try this based on our situation
Bird has had not been outside and has been confined indoors in isolation since recieved.
Please give it the home it deserves.
Appreciate the care you took getting it to us!!!
Need some color on my team. Had some sion couple years ago when i had a partner who sick and could not care for his own birds. He liked sions so i bought some from you on pigeonauction.com. We alot of fun his sions against my team .He has since past on. His family called me and thanked me for letting fly with me he really looked forward race day. HE WON EVERY WEEK
