I have done the pigeons in the sunflower fields outside of Pretoria. I did one day of wingshooting after I'd gotten my animals. The shooting is constant and the pigeons generally flew just above the sunflowers. About head high. As soon as they saw me the aerial acrobatics were amazing. Very difficult shooting buy also very fun. I was shooting about the 10th of May last year. The sunflowers were drying but had not been harvested. The shooting reminded me of the videos I've seen of grouse shooting on the moors. But the birds do crazy maneuvers as they pass.
