We often hear of Spireites coming to the Proact from around the world, but not many of them fly themselves to the home of Chesterfield FC.
The rare crag martin, which has attracted bird watchers from around the country to the town in the last two weeks, and having seemed to have found a place to stay in the crooked spire, has now spread it's wings to come to the home of the Spireites.
Not put off by Saturday's loss to Oldham Athletic, both the bird, a large number of watchers and our own club photographer Tina Jenner were at the Proact on Sunday to catch a sighting of the bird, which usually resides in Southern Europe.
"I wasn't planning to come along and try to take photos of it, but I drove past the Proact on Sunday and saw lots of people out with binoculars so I stopped and asked them what they were up to.
"I rushed home, picked up my camera and rushed back to the ground, where I spent three hours waiting and then taking pictures of the bird."
And after a rain-sodden afternoon doing her day job on Saturday and taking photos of the likes of Ian Evatt and Lee Novak, Tina's patience was rewarded with the crag martin image you can see above.
"There was a function in the main stand so the stadium security guard thought the crag martin was probably in the East Stand somewhere where is was quieter.
"After a couple of hours it came out and flew around the pitch. I got some blurry photos as it flew low by the grass and then as it swooped up and down I got the photos with the floodlights, and I think I'm the only person who managed to capture the rare bird and the stadium that way.
"It was a funny way to spend my Sunday - especially after all the wet weather on Saturday and just wanting to be nice and dry inside for the rest of weekend!"
